【三輪山麓「纏向」にやって来た王権 大和歴史証言-12】



桜井市立埋蔵文化財センターでの展示パネルの一文要旨。
〜<マキムクの時代>
弥生時代を通じて活発な活動が繰り広げられていた拠点集落では、
2世紀末から3世紀初頭になると環濠が埋め立てられ、
集落の規模も小さくハッキリしなくなることがわかっています。
このような集落構造の変化は、それまでの弥生社会の枠組みが崩れたことを
あらわすとともに、新たな古墳時代の幕開けを告げると考えられています。
●弥生集落が衰退・廃絶に向かうちょうどその頃、
これらと入れ替わりに出現するのが纏向遺跡です。●
土器の形式では庄内0式期(3世紀初頭)と呼ばれる時期に当たり、
弥生時代には集落が無かった場所に突如として径約1kmという
巨大な「マチ」が出現したのです。
それはそれまでの農耕的色彩の強い弥生時代集落のような自然発生的な
ものではなく、きわめて強い政治的な意図のもとに作り上げられた
「マチ」であると考えられています。〜

おお、であります。
少なくとも考古的発掘事実からはこのような推論が確定している、と。
そしてそうした事跡は記紀の記述では10代崇神帝に擬せられるという。
以下、Wikiの「崇神天皇」の条から要旨引用。
〜即位3年、三輪山西麓の瑞籬宮(みずかきのみや)に都を移した。
即位5年、疫病が流行し人口の半ばが失われた。祭祀で疫病を治めようとした天皇は
翌年に天照大神と倭大国魂神を宮中の外に出すことにした。
天照大神は豊鍬入姫命に託し(現在の三輪山麓の)檜原神社に祀らせた。
即位7年「朕の世になり災害が多い。亀卜にて見極めよう」と詔して、
八百万神を集めて占った。すると倭迹迹日百襲姫命に大物主神が乗り移って
自分を祀るよう託宣した。そのままに祭祀を行ったが霊験がなかった。
そこで天皇は沐浴斎戒し「願わくば夢に教えて神恩を示してほしい」
と祈った。するとその夜の夢に一人の貴人が現れ自ら大物主神と称して
「もし我が子の大田田根子を以って我を祭れば平安となる」と告げた。
そこで大物主神の子孫・大田田根子が探し出され大物主神を祭る神主となった。
三輪山を神体とする大神神社の創始。すると疫病は終息し五穀豊穣となった。〜


2世紀末から3世紀初頭という年代は飛鳥時代からは200年以上前。
また文中にある「倭迹迹日百襲姫命」とは箸墓古墳の被葬者。
また、大物主神とは出雲系の国造りの神・大国主神の異称とされる。
このような記紀の記述と考古的発掘成果を踏まえれば、
この纏向遺跡は、飛鳥以前の王都の痕跡であると考えられて不思議ではない。
住宅をライフワークにしてきた人間としては日本の「マチ」始原説は、響く。
飛鳥宮ですら深い迷宮のように思えていたことからすると
その底深さに慄くばかりではありますが、いまのところ
こうした推論について否定しうる根拠を見いだせないでいます。
歴史のひとつの興味深い推論だと思わせられますね。・・・

Kingship that came to “Makimuku” at the foot of Mt. Miwa, Yamato Historical Testimony-12
In the 10th Emperor Sujin’s relics, he “moved the capital to the western foot of Miwa Mountain. He founded the Izumo-derived Ookami Shrine in hopes of remedying plague and disease. Fusion of myth and archaeological excavation. The fusion of mythology and archaeological excavation.

Abstract of a sentence from an exhibition panel at the Sakurai Municipal Center for Archaeological and Cultural Properties.
~The Makimuku Period
The base village, which had been active throughout the Yayoi period, was filled up with a moat encircling the village from the late 2nd to the early 3rd century.
In the late 2nd to early 3rd century, the moat encircling the village was filled in, and the size of the settlement became smaller and less clearly defined.
In the late 2nd to early 3rd century, the moat encircling the settlement was filled in, and the settlement scale became small and indistinct.
Such a change in settlement structure indicates that the framework of Yayoi society had collapsed.
This change in settlement structure is thought to indicate the collapse of the previous framework of Yayoi society and the beginning of a new Kofun period.
Just as the Yayoi settlements were beginning to decline and die out, the Kofun period was beginning to emerge in their place.
The Makimuku ruins appeared in place of the Yayoi settlements that were declining and dying out. The pottery type is Shonai 0.
The pottery forms of the site correspond to the Shonai 0-period (early 3rd century), which is considered to mark the beginning of the Yayoi period.
A huge “Machi” of about 1 km in diameter suddenly appeared in a place where there had been no settlements in the Yayoi period.
A huge “Machi” of about 1 km in diameter suddenly appeared in a place where there had been no settlements in the Yayoi period.
It was not a spontaneous emergence like the settlements of the Yayoi period, which had a strong agricultural flavor, but rather an extremely strong political intention.
but rather a “Machi” that was created with a very strong political agenda.
It is believed to be a “Machi” created with a very strong political agenda. 〜Oh.

Oh, yes.
At least, such an inference is confirmed by archaeological excavations.
And the Chronicler’s description of such an event is said to be the 10th emperor of the Chronicles.
The following is a summary quote from the article “Emperor Sojin” in Wiki.
〜In the third year of his reign, he moved his capital to the palace of Mizukakinomiya at the western foot of Miwa Mountain.
In the 5th year of his accession, an epidemic caused the loss of half of the population. The emperor tried to cure the plague with rituals.
The following year, he decided to remove the deities Amaterasu and Wakatonokotama from the palace.
He entrusted Amaterasu to Toyohuenirihime no Mikoto and had her enshrined at Hinohara Shrine (at the foot of present-day Miwa Mountain).
In the 7th year of his accession to the throne, he said, “In my reign, there have been many disasters. I shall use kameutsu (divination by tortoises) to determine the cause.
He gathered the eight million gods and divined their fortunes. Then, the deity Omononushi took over and enshrined himself in the deity.
and commanded that he be worshipped. He performed the ritual as it was, but it did not produce any miraculous results.
The emperor then bathed and prayed, “I wish you would teach me in my dreams and show me the favor of the gods.
The emperor bathed and prayed, “I wish you would show me your divine favor in my dreams. Then, in a dream that night, a nobleman appeared to him, calling himself the deity Omotonushi.
If you worship me with my son Otadaneko, you will be at peace.
Ootadeneko, a descendant of Omotonushi, was found and became the deity who worshipped Omotonushi.
He became the founder of Ogami-no-sha Shrine, with Mount Miwa as its sacred body. The plague ended and the harvest was bountiful. 〜From the end of the 2nd to the beginning of the 3rd century

The late 2nd to early 3rd century is more than 200 years before the Asuka period.
The “Wajaku-no-Hyakuso no Mikoto” in the text refers to a person buried in the tomb of Chopstick Tomb.
Also, “Ohmononushi” is said to be a variant of “Okuninushi,” the god of nation-building of the Izumo lineage.
Based on the descriptions in the Chronicles and the archaeological findings, the
It is not surprising that the Makimuku site is thought to be a trace of a pre-Asuka royal capital.
As a person who has made housing his life’s work, the theory of the origin of “Machi” in Japan resonates with me.
Given the fact that even the Asuka Palace seemed like a deep labyrinth
I can only shudder at the depths of the labyrinth, but at the moment I have no
I have not been able to find any evidence to deny this theory.
It is an interesting theory of history. The fusion of mythology and archaeological excavation.

【纏向王権の象徴建築 大和歴史証言-11】




飛鳥の探訪から始めたブログ連載ですが、纏向にスピンアウトしてきたので、
「大和歴史証言」とこっそりタイトルを遷移させました(笑)。
こちらの方は飛鳥の時代よりもさらに遡った時代相ということになる。
橿原考古研究所による考古発掘の活発化から、
この三輪山の麓の桜井市には桜井市立埋蔵文化財センターが設立され
さらに桜井市纒向学研究センターという研究組織まで作られている。
〜<日本国家と日本文化の原像を解明するためのキーワード>
桜井市とその周辺に広がる、磯城、山辺、磐余の地域は、飛鳥に繋がる
日本国家誕生の舞台です。とくに纒向遺跡はヤマト王権の大王都が最初に置かれた場所とされ、
まさにその出発点にあたります。
纒向遺跡とその周辺地域の調査と研究を充実させ、そこからこの国の成り立ちや
歴史、文化の原像を解明するための横断的な「学」それが「纒向学」の骨子です。〜
というように高らかに宣言される趣旨がHPに書かれている。
そのような宣言の契機になったのが、模型のような建築遺構の発掘。

昭和46年に始まる纏向遺跡調査でも全国に驚きを持って報道された建築群。
展示で模型復元されているのはBCDという3つの建築。
写真のいちばん左手のBは東西2間南北3間。柱穴は遠景と隅丸方形で直系50-60cm。
柱の痕跡が残っていたものもあり直系20cmの木材利用か。
写真真ん中のCは東西1間南北3間。柱穴は円形と楕円形で径70-80cm。
「近接棟持柱」と呼ばれる柱が壁よりも外側にあった。
伊勢神宮などにこの都合6本の柱構造建物は類似例が見られる。
そしてもっとも大きなDは想像復元では入母屋が採用されている。
東西4間南北4間だけれど長さに違いがあって、
東西12.4m 南北19.2mという大型建築になっている。
見た瞬間に既視体験に襲われ、飛鳥浄御原宮の「エビノコ郭」を類推した。

こちらの写真は橿原考古博物館展示の復元模型。
入母屋構造で、建築に「縁」が回されていて手すりが据えられている。
そして束柱によって建物は地上から浮き上がったようにデザインされている。
その縁に向かって3つの階段が装置されている。
いかにも日本的王権威信建築といえる佇まい。

考古的発掘調査に基づいて復元が試みられて
古代建築の知見なども集中されてこういう形態の建築とされた。
そうするとこの王権とはなんであったのか、というテーマが浮上してくる。
飛鳥の宮に先行する王権の所在地域としての纏向の証拠とされる。
そうですね、ナゾの古代史の時代にわれわれを導いていってくれる。

Symbolic Architecture of the Makimuku Kingship Yamato Historical Testimony-11
The Yamato Kingdom of Japan preceded Asuka. The remains of its prestige architecture existed at the Makimuku site. The site is expected to bring us closer to the riddle of ancient history. …

I started this blog series with an exploration of Asuka, but since it has spun out into a coherent series
I secretly transitioned the title to “Yamato Historical Testimony” (laugh).
This one is a period phase that goes back even further than the Asuka period.
Since the Kashihara Archaeological Institute of Kashihara has been active in archaeological excavation, we have been able to find
Sakurai Municipal Center for Archaeological Properties was established in Sakurai City at the foot of this Miwasan Mountain, and
The Sakurai Municipal Center for Buried Cultural Properties was established in Sakurai City at the foot of Mt.
〜<The key word to elucidate the original image of the Japanese nation and Japanese culture.
Sakurai City and the surrounding areas of Isogi, Yamabe, and Panyo are the birthplace of the Japanese nation
The area surrounding Sakurai City is the stage of the birth of the Japanese nation, which is connected to Asuka. In particular, the site of the Makimuku Ruins is believed to be the first location of the great capital of the Yamato Kingdom, and is the very starting point of the Yamato Kingdom.
It is the very starting point of the Yamato Kingdom.
We will continue to research and study the site and the surrounding area, and
The framework of “Garakko-gaku” is a cross-disciplinary “study” to elucidate the origins, history, and culture of the country from there. 〜The “study of the ancient ruins” is the essence of the “study of the ancient ruins.
The website of the museum states the purpose of this declaration in such a high manner.
What triggered such a declaration was the excavation of architectural remains like a model.

The architectural group was reported with surprise throughout the country during the investigation of the Makimuku ruins that began in 1971.
The three architectural models in the exhibition are the BCD.
B, on the leftmost side of the photo, measures 2 ken (east-west) by 2 ken (north-south) by 3 ken. Pillar holes are 50-60 cm straight in the distant view and rounded corner square.
Some traces of pillars remained in the holes, suggesting that they were made of wood measuring 20 cm in the straight direction.
Photo C in the middle is 1 east-west to 3 north-south to 1 west-east to 3 north-south. The pillar holes are circular or elliptical and 70-80 cm in diameter.
The columns, called “proximity munemochibashira,” were located outside the walls.
Similar examples of this six-pillar structure can be seen at the Ise Jingu Shrine and other shrines.
The largest D in the reconstructed building is an irimoya, or a gabled roof.
The length of the building is different, though it is 4 ken (east-west 4 ken, north-south 4 ken).
It is a large building, measuring 12.4 m east to west and 19.2 m north to south.
The moment I saw it, I had a déjà vu experience and thought of the “Ebinoko-kaku” of the Asuka Jomihara Palace.

The photo here is a restored model exhibited at the Archaeological Museum of Kashihara, Nara Prefecture.
It has an irimoya (gabled) structure, with an “edge” around the building and a railing.
The building is designed to rise above the ground by means of the support pillars.
Three staircases are set toward the edge of the building.
The appearance of the building is very Japanese in its prestige and prestige of royal authority.

The restoration of the building was attempted based on archaeological excavations.
The restoration was attempted based on archaeological excavations, and the knowledge of ancient architecture was concentrated to create this type of architecture.
This raises the theme of what this royal authority was.
It is said that this is evidence of the Makimuku area as the location of the royal authority that preceded Asuka’s palace.
Yes, it leads us to the age of mysterious ancient history.

【纏向〜まきむく遺跡スピンアウト 飛鳥歴史証言-10】



奈良盆地での歴史探検というのはまるで迷宮。
そこここで奥行きの深い事跡が発見されて深くとらわれる。
たぶん今後の最大の楽しみになっていくことは間違いがない。
そういう先達、飛鳥の万葉館のボランティアの方に遭遇。
つたない歴史探検ですがいろいろな現地での最新情報をお教え戴いた。

大神神社の麓の箸墓古墳は、宮内庁から「大市墓」として
第7代孝霊天皇皇女の倭迹迹日百襲姫命の墓に治定されている。
また笠井新也氏の研究以来、邪馬台国の女王卑弥呼の墓とする学説がある。
百襲姫の陰部に箸が突き刺さり絶命したことが名前の由来。〜以上Wiki引用。
そしてこの周辺の「纏向遺跡群」からは飛鳥よりも古い時代の発掘が
相次いできているというご案内をいただいたのです。


地図や航空写真で示すような位置関係にあるのが三輪山・大神神社と箸墓古墳。
飛鳥宮からは北東へ9.7kmの距離という位置関係。
飛鳥の都、乙巳の変を考えれば645年前後。
一方で箸墓古墳は、宮内庁発表を踏まえると孝霊天皇死亡年が紀元前215年。
そして三輪山の大神神社の伝承もそういった時期と重なる。
なにしろ、大神神社は出雲系の祭神伝説を持ち自然崇拝として
いまでも三輪山本体をご神体としている神社。
まぁこういった神話の類はそのまま信じるわけにはいかないけれど
しかし社会としてのある事情を伝えている部分があるのだと思います。
現代はそれを考古的に丹念に「掘り出す」ことが可能にもなってきている。
先述のご案内は、そうした考古発掘がこの遺跡で相次いできて
飛鳥の地との相関関係で興味深い展開になってきているという次第。

遠く北海道にいると歴史とは考古と一体のものが常識。
明治以前の言葉を持たない人間痕跡と丹念に向き合う中で
生々しいいのちの痕跡が出現していくというダイナミズム。
そういう現代的合理主義によって歴史が採掘されていくことは喜ばしい。
ひたすら物証を求めていくことで想像力を深めて
現実の「モノ」と真摯に向き合って事実を解明していく。
そういう手法で飛鳥の地、奈良盆地にスポットを当てていく。
どちらかというと「文献主義」が歴史学の基本とされてきたけれど、
やはり考古的発掘は紛れもない事実をあきらかにしていく。
北海道人にもわかりやすい考古事実解明はすばらしいと思っています。
ということで、桜井市立埋蔵文化財センターでの纏向遺跡探究。
どっぷりと浸りきっておりました。まだその余韻の中にいます(笑)。
たぶんこういった興奮ってDNA的な部分での刺激のような気がする。

Asuka Historical Testimony – 10] Spin out of Makimuku Ruins
The reality of the Nara Basin in the period even older than Asuka. Deep into the area around Oomiwa Shrine and Chopstick Tomb, where a series of archaeological discoveries have been made. …

Historical exploration in the Nara Basin is like a labyrinth.
Here and there, deep traces of history are discovered, and we are deeply caught up in the mystery.
I am sure that this will probably be my greatest pleasure in the future.
I met a volunteer from the Manyokan Museum in Asuka.
He gave me the latest information about the area, despite my poor historical exploration.

The Chopstick Tomb Tumulus at the foot of the Ojinja Shrine has been designated by the Imperial Household Agency as the “Oichi Tomb” by the 7th Emperor Koryo.
The tomb is designated by the Imperial Household Agency as the tomb of the 7th Emperor Koryo’s daughter, Wajaku-no-Hyakuso-mikoto.
Since the research of Mr. Shinya Kasai, there is a theory that it is the tomb of Himiko, the Queen of Yamataikoku.
The name comes from the fact that a chopstick pierced Princess Hyakusohime’s pubic region, causing her to die. 〜The above is a quote from Wiki.
And, there have been a series of excavations from the “Mukai ruins” in the vicinity of the site that date back to a period older than that of Asuka.
The “Makimuku ruins” in this area have been excavated one after another in the period older than Asuka.
As shown in the map and aerial photographs, the Miwasan-Okami Shrine and the Chopstick Tomb Tumulus are located in the same position.
The location is 9.7 km northeast of Asuka Palace.
Asuka’s capital, around the year 645 considering the Otsumi Incident.
On the other hand, according to the announcement by the Imperial Household Agency, Emperor Koryo died in 215 B.C. The tomb is located 9.7 km northeast of the Asuka Palace.
The legend of the Ogami Shrine on Mount Miwa also coincides with such a period.
The legend of Ookami Shrine is based on the Izumo lineage, which is a form of nature worship.
The shrine is still a Shinto shrine with the main body of Miwa as its deity.
Well, we cannot believe in these myths as they are.
But I believe that they convey a certain situation as a society.
Today, it is possible to archaeologically and painstakingly “dig out” such information.
The aforementioned information is based on the fact that such archaeological excavations have been carried out one after another at this site.
The above-mentioned information is based on the fact that such archaeological excavations have been carried out one after another at this site, and that interesting developments are taking place in correlation with Asuka.

When you are far away in Hokkaido, it is common knowledge that history is an integral part of archaeology.
In the course of painstakingly confronting the traces of human beings who did not have words before the Meiji period
The dynamism of the emergence of fresh traces of life.
I am glad that history is being mined by such modern rationalism.
We deepen our imagination by relentlessly seeking for physical evidence.
We are sincerely confronting the real “things” to clarify the facts.
This is how we spotlight the Asuka area and the Nara Basin.
Although “literalism” has been considered the basis of historical studies, archaeological excavations are still an indisputable part of it.
However, archaeological excavation reveals undeniable facts.
I think it is wonderful that archaeological facts are revealed in a way that can be easily understood by the people of Hokkaido.
So, I explored the Sumamukai Ruins at the Sakurai Municipal Archaeological Center.
I was fully immersed in the experience. I am still in the aftermath of that (laugh).
I think this kind of excitement is probably stimulated by our DNA.

【史跡「飛鳥宮跡(板蓋宮)」 飛鳥歴史証言-9】



昭和47年に「史跡・伝飛鳥板蓋宮跡」として史跡指定された地域は
平成28年10月に名称が史跡「飛鳥宮跡」と変更された。
日本書紀などでは推古天皇から持統天皇に至る7世紀の約100年間、
歴代天皇の宮が次々と飛鳥の地に造営されたと記されている。
昭和34年以来、橿原考古学研究所の発掘調査が続けられてきた。
宮の中心部分は東西約158m、南北約197mの長方形区画(内郭)で
区画の内側では大規模な掘立柱建物や石敷き広場などを発見。
この銘板の置かれた位置のすぐ左手に内郭北東側の建物の柱配置・井戸を
復元しているものです。
この内郭を囲むように建物や柱列、石組み溝などが営まれていて、
それらを「外郭」と呼んでいます。
内郭の東南側にはエビノコ大殿とされる大規模な掘立柱建物を中心にする
区画が存在することも確認されています。
これらの遺構は斉明天皇の「後飛鳥岡本宮」および天武持統天皇の
「飛鳥浄御原宮」などに相当するものと考えられている。〜以上、銘文より。

のちの藤原京や平城京などは東アジア世界との交流、相克が
激しさを増していった国際情勢を踏まえて、
いかにも都城にふさわしい「都市建設」が意図されていったけれど、
それ以前の王宮とは、天皇の居館を中心にした必要十分な構成。
これまで紹介してきた池工房や飛鳥寺とも指呼の間で数百メートルの位置。
現在、この宮跡に来て見ると周辺は水田地帯が広がっていて
また、当初は石敷きと区割りの石が史跡指定当時は明確だったのが
やがて草深くなってきていると見受けられる。
印象で言えば、非常に素朴な権力機構の遺構と感じられる。
仁徳帝が民の家から煙が上がっていない様子を見て節約に励んだという故事が
素直に受け止め可能なようにも思える。
石で踏み固めた権力痕跡がやがて田んぼになり草に覆われて
いかにも牧歌的な風景に還元されている平和な様子。

こういう風景に佇んでいると、
日本の原初の王権は本来この程度であったものが、
東アジアの超大国・唐が出現したことでそれへの外交対応、独立維持が
この国の権力機構の進展に非常に大きな要因だったとわかる。
現実に半島の動乱の政治・軍事情勢〜白村江戦争の結果、
百済の遺民が大挙日本に帰化して、唐の強大を身を以て知ったかれらが
亡命したこの日本の王権を強化することに必死だった。
そういった歴史の見方に強く同意したくなる。
中国の強権はつねに半島地域に対して剥き出しの暴力性を示し
列島社会はその脅威に備えた対応をしてきたのだと。
その安全保障的行動原理から律令と仏教を積極的に受け入れたという展開。
日本史の底流にこういう国際関係論があったことがわかる。
海を挟んでいることから幸いにして大陸的男系DNA根絶やし大量殺戮からは
歴史的に逃れられてきたとのが歴史の実相なのでしょう。
日本人の「平和意識」というものの原点なのかも知れませんね。

Asuka Palace Site (Itabukinomiya)” Asuka Historical Testimony-9
A land with vigorous natural resilience. The central area of power is quickly reduced to a landscape of rice paddies and grass. It is a landscape of the origin of Japan’s pacifism. …

The area designated as a historic site in 1972 as “Historic Site, Den Asuka Itabukinomiya-gū Ato” was
The name was changed to “Asuka Palace Site” in October, 2008.
According to the Nihon Shoki (Chronicles of Japan) and other records, the palaces of successive emperors were located one after another for about 100 years in the 7th century from Emperor Suiko to Emperor Jito.
The Chronicles of Japan and other documents state that the palaces of successive emperors were built one after another in Asuka during the 100 years of the 7th century from Emperor Suiko to Emperor Jito.
Since 1959, the Archaeological Institute of Kashihara has continued excavations.
The central part of the palace is a rectangular section (inner wall) measuring approximately 158 m east to west and 197 m north to south.
A large dugout pillar building and a stone-paved plaza were found inside the inner wall.
The pillar layout of the building on the northeast side of the inner wall and the well are restored to the immediate left of the location where this nameplate is placed.
This is a restoration of the well and the pillar layout of the building on the northeast side of the inner wall.
The buildings, rows of pillars, and masonry ditches surrounding the inner wall are called the “outer wall.
These are called the “outer wall.
On the southeast side of the inner wall, there is a large hottate-bashira building, which is believed to be the Ebinoko-daiden.
These remains are the remains of the Saimei Tenmangu Shrine.
These remains are related to the “Go-Asuka Okamoto Palace” of Emperor Saimei and the “Asuka Kiyomihara Palace” of Emperor Temmu Mochito.
These remains are thought to correspond to the “Asuka Jomihara Palace” of Emperor Saimei and the “Asuka Jomihara Palace” of Emperor Temmu Jito. 〜The above is from the inscription.

The Fujiwara-kyo and Heijo-kyo Capital later became the center of international
The Fujiwara-kyo and Heijo-kyo Capital were built as “cities” that were suitable for a capital city in light of the international situation
The later Fujiwara-kyo and Heijo-kyo were intended to be “city-builders” that would be suitable for a capital city, but
The royal palaces of the earlier period were composed of a necessary and sufficient structure with the emperor’s residence at the center.
It is located within a few hundred meters from Ikegakobo and Asukadera, which we have introduced so far.
When we come to this palace site today, we see that the surrounding area is covered with rice paddies.
In addition, the stone pavement and ward stones were clear at the time of the initial designation as a historic site.
It can be seen that the grass is eventually becoming deeper and deeper.
In terms of impression, it seems to be the remains of a very simple power structure.
The legend that Emperor Nintoku saw no smoke rising from the houses of his people and encouraged them to save money seems to me to be a story that can be accepted honestly.
The traces of power stamped out with stones are still there.
The traces of power trampled with stones eventually turned into rice paddies and covered with grass.
The peaceful scene is reduced to a pastoral landscape.

Standing in such a landscape
I am reminded that Japan’s original kingship was originally only this small, and that the Tang Dynasty, the superpower of East Asia, was a great power.
The emergence of the Tang Dynasty, the superpower of East Asia, and its diplomatic response to the Tang Dynasty, as well as the maintenance of independence, were very important in the development of the country’s power structure.
The emergence of the Tang Dynasty, the superpower of East Asia, was an extremely important factor in the development of the country’s power structure.
In reality, the political and military situation on the peninsula was in turmoil, and as a result of the Baekchon River War
The Baekje people were naturalized in Japan in great numbers, and they learned firsthand of the might of the Tang Dynasty.
They were desperate to strengthen their royal power in exile in Japan.
I am inclined to strongly agree with this view of history.
Chinese power has always shown itself to be openly violent toward the peninsular region, and island societies were prepared for the threat.
The archipelagic societies have responded to this threat.
The security principle of the Japanese government led to its active acceptance of the Ritsuryo Code and Buddhism.
It is clear that this kind of theory of international relations was at the bottom of Japanese history.
Fortunately, the fact that Japan is located on the other side of the sea has historically allowed it to escape the continental eradication of its male DNA and the genocide of its people.
The reality of history is that Japan has historically escaped genocide by eradicating continental male DNA.
This may be the origin of the Japanese sense of peace.

【関東梅雨明け宣言後、北海道にエゾ梅雨?】


昨日は久しぶりのアース21札幌での例会・現場見学会。
たっぷりと5件の現場を見学することができました。
そのうち完成間近で内装もほぼ終わっている現場は1件だけで
その他は構造と断熱段階のものが多かった。
やはりリアルに現場での寸法感覚を確認しながら見るのは
刺激感が全然違う。
感染症での閉塞状況を体験して、やはり人間感受性の多様性、
感覚がリフレッシュされて反応しているのがわかる。

ということでしたが、札幌はここのところ雨続き。
バスでの移動は「密を避ける」ということで回避して
各自のクルマでの移動でしたが、それでもときどき豪雨状態で
一時は全身が雨まみれに。
どうやら関東地区が梅雨明け宣言したあとの梅雨雲が一気に北上し
写真のような雨雲状態のようです。
北海道は梅雨がない、というのが長い民族的記憶で、
北国のさわやかな初夏というのが「天国に一番近い」季節の印象だった。
それがいまや、全国の梅雨を全部集めたような天候であります。
一方で東京・関東は数日間高温が続いているようですね。
そこに電力の逼迫状況があって連日「節電」令のような状況が続いている。
熱中症による搬送が急増しているとも言われている。

象徴的な局面が否応なくやってきているように思える。
なにより安定的な電力は高度に発展した社会では不可欠な要素。

After Kanto declared the end of the rainy season, Hokkaido is experiencing the Ezo rainy season?
Sapporo is like the peak of the rainy season. Kanto is in the midst of saving electricity all at once. Aggressive Russia and energy crisis, what will be the will of the people? …

Yesterday was the first meeting and site tour at Earth21 Sapporo in a long time.
We were able to visit a total of five sites.
Of these, only one site was nearing completion and the interior was almost finished.
The rest were in the structural and insulation stages.
After all, it is a totally different and stimulating experience to see a real site while confirming the dimensions of the building.
The sense of stimulation is totally different.
Experiencing the blockage situation caused by the infection, I could see the diversity of human sensitivities and
I could see that people’s senses were refreshed and reacted to the situation.

But it has been raining in Sapporo for a while now.
We avoided traveling by bus to “avoid the density.
We avoided traveling by bus to “avoid density” and took our own cars, but it was still raining heavily at times.
But even so, it was still raining heavily at times, and at one point our bodies were covered with rain.
It seems that after the rainy season was declared over in the Kanto area, the rainy clouds moved northward at once.
The rain clouds are like the ones in the picture.
My long national memory is that there is no rainy season in Hokkaido.
The impression of a refreshing early summer in northern Japan was that it was the season “closest to heaven.
Now the weather is like a collection of all the rainy seasons in Japan.
Meanwhile, Tokyo and Kanto seem to be experiencing high temperatures for several days.
There is a tight power supply situation there, and the situation is like a “power-saving” decree every day.
It is said that the number of people being transported to hospitals due to heat stroke is increasing rapidly.
There is also an election going on at the same time that must reflect the will of the people.
It seems that a symbolic phase is inevitably coming.
Above all, stable electric power is an essential element in a highly developed society.
The unprecedented situation of Russia’s invasion of Ukraine
The unprecedented invasion of Ukraine by Russia is accentuating the global energy crisis.
Security and energy issues are the most important issues in modern society.
What kind of voting behavior will the Japanese people take as they choose their future?
I believe that we are at a turning point of considerable magnitude, and it is manifesting itself in this way.

But rain is a godsend to nature.
The colorful flowers are a feast for the eyes.
Well, it’s been raining all morning today.
Now I am wondering what to do about my walk.
So, we have temporarily taken a break from our serial theme project today.

【アマルガム中毒を乗り越え大仏鍍金 飛鳥歴史証言-8】



飛鳥の時代のひとつの終焉のカタチは
東大寺大仏の開眼、造立ということだったように思う。
日本という国家、その共同幻想の基軸となった大きな柱は
鎮護国家思想であり、国内諸国に国分寺を建立し
奈良にはその中枢として東大寺を建立することでその思想の完成とした。
さらにその国家大方針の中核が大仏だったのでしょう。
後の世で鎌倉にも大仏が作られたのは、律令国家とは別思想の
武家政権としての中心軸と考え、先例に倣ったのだと思える。
この奈良大仏の造立・鍍金事業は草創期国家にとって想像を絶する大事業。

752年に造立されたもので当時の鋳金工芸の粋を集めたわが国最大の鋳仏であり、
世界でも類例をみない。そして現代の工業技術への多くの啓示が秘められている。
多湿な風土をもつわが国で戦火に2度も見舞われながら腐食現象が起きていない。
これは建立当時の先人の技術“焼付け金メッキ”が行なわれたからといわれる。
大仏を造ったのは百済亡命者・国骨富の孫、国中真麻呂大仏師。
そして大鋳師・高市真国、高市真麻呂の家来の技術者など延べ42万3,000余人、
役夫218万人を使って大仏本体鋳造3年、組立てに2年、仕上げと塗金に6年、
計11年の歳月を費してやっと完成している。
高さ16m余、幅約12m、重さ112.5tという巨大さで蓮華座に坐っている。
752年(天平勝宝4)4月9日に大仏開眼会が挙行されて完成を祝ったが
鍍金メッキ作業はその後から5年掛けて行われたとされる。
「塗練金4,187両1分4銖、為滅金25,134両2分銖、右具奉。
金4,187両を水銀に溶かしアマルガムとしたもの25,224両を仏体に塗った。
金と水銀を1:5の比率で混合しアマルガムとした。
アマルガムによる金メッキが始まってから塗金仕事をする人々に病気が流行した。
この不思議な病気の原因はまさに「水銀中毒」。
蒸発する水銀を吸うことでの中毒と真相をつきとめた大仏師・国中公麻呂は、
東大寺の良弁僧上とともに毒ガスマスクを工夫して病気発生を予防した。
科学技術の進歩は公害が付きもので、これを克服しなければ進歩はない。
<東京都鍍金工業組合「奈良の大仏と表面処理」より要旨>

唐という強権国家の登場の危機的な東アジア世界情勢を受けて
必死に近代国家建設に取り組んだこの時期の歴史が生々しく立ち上ってくる。
奈良期は疫病や地震などの災害が多発したと言われる。
この大仏鍍金での公害発生などは極めつけの災禍と思われる。
悩んだ聖武帝は自ら発願した大仏造立でありながら転々と遷都を繰り返している。
しかしこういう「工業発展」の取り組みがその後の日本社会の高度化に
どれほどの貢献をしたか、計り知れないものがあると思う。

[Overcoming Amalgam Poisoning and Plating the Great Buddha Asuka Historical Testimony-8
The mixture of gold and mercury struck the workers as pollution. The “Jingo-no-Kokoku” of hardship. Emperor Shomu must have been deeply distressed. …

One way to end the Asuka period was the opening and construction of the Great Buddha at Todaiji Temple.
The great statue of Buddha at Todaiji Temple was the end of the Asuka period.
The major pillar that served as the basis of the common illusion of the nation of Japan was the idea of a “shin-governed state.
The main pillar of the Japanese nation, the basis of its common illusion, was the idea of a nation that would protect and defend the nation.
The idea was completed with the construction of the Todaiji Temple in Nara, which served as the center of the nation.
Furthermore, the core of this national policy was probably the Great Buddha.
The reason why the Daibutsu was also built in Kamakura in the later period was because of the idea of the central axis as a warrior government, which was a different idea from the Ritsuryo State.
The reason why the Daibutsu was also built in Kamakura in the later period seems to be that it was considered as the central axis of the samurai government and followed the precedent.
The construction and gilding of the Great Buddha in Nara was an unimaginably large undertaking for the pioneer state.

Built in 752, it is the largest cast Buddha in Japan, the culmination of the best of the metal casting craftsmanship of the time, and is unparalleled in the world.
It is also unparalleled in the world. It is also a revelation to modern industrial technology.
In Japan, which has a humid climate, the Buddha was twice exposed to war and fire, yet has not experienced any corrosion.
It is said that this is due to the excellent “baking gold plating” technique used by the predecessors when the statue was built.
The Great Buddha was built by the great Buddhist priest Kuninaka Manamaro, grandson of the Baekje exile Kokkotomi.
The Great Buddha Master Kuninaka Manamaro, grandson of the Baekje exile Kunikotsufu, built the Great Buddha, and a total of more than 423,000 people, including the great castor Koichi Makoku, Koichi Manamaro’s retainers and technicians.
It took a total of 11 years, including 3 years for casting, 2 years for assembly, 6 years for finishing and lacquering, and 2.18 million workers.
It took a total of 11 years to complete the construction.
It is 16 meters high, 12 meters wide, and weighs 112.5 tons, and sits on a lotus throne.
The completion of the statue was celebrated with an opening ceremony on April 9, 752 (Tempyo-shoho 4).
The gilding and plating work is said to have been carried out over the next five years.
The gold was plated with 4,187 gold pieces and 25,134 gold pieces.
The 25,224 kyos of gold (4,187 kyos) dissolved in mercury to form an amalgam was applied to the body of the Buddha.
Gold and mercury were mixed in a ratio of 1:5 to make an amalgam.
After the amalgam gold plating process began, there was an epidemic of illness among those who worked in the gold plating industry.
The cause of this mysterious disease was precisely “mercury poisoning.
Kuninaka Koumaro, a great Buddhist priest, discovered that the poisoning was caused by inhaling evaporating mercury.
Together with the monk Ryoben of Todaiji Temple, he devised today’s poison gas masks to prevent the outbreak of the disease.
Scientific and technological progress is accompanied by pollution, which must be overcome before progress can be made.

In response to the critical world situation in East Asia with the emergence of the powerful Tang Dynasty
The history of this period, in which people desperately worked to build a modern state, comes vividly to the fore.
The Nara period is said to have been rife with plagues, earthquakes, and other disasters.
The pollution caused by the plating of the Great Buddha is considered to be the most serious disaster.
Emperor Shomu, who was troubled by the disaster, repeatedly relocated the capital from one place to another, even though he himself had initiated the construction of the Great Buddha.
However, it is difficult to say how much this kind of “industrial development” contributed to the subsequent advancement of Japanese society.
I think it is immeasurable how much these “industrial development” efforts contributed to the subsequent advancement of Japanese society.

ふだんは正直に自分の気持ちを表せない人間でも、
ああいった形式の中ではごく自然に表出させられる。
「どうせ、はないちもんめなんだから、思い切って・・・」
人間社会が考えた子孫繁栄維持のたぐいまれな知恵なのだろうと思う。
口に出して言って見ると相手の表情がそのときクローズアップされて
「あ、まんざらでも無いのか、やった!」という展開(笑)。
さまざまな楽器の演奏というのも、その雰囲気作りだともいえる。
万葉集という「歌」の基本はこうした相聞文化。

[Utagaki and Performing Arts, Male-Female Love Culture Asuka Historical Testimony-7
◎◎-chan wanting “Hanaichimonme” collective hearing and confession. This is a human culture that is all about the survival of offspring. The origin of the entertainment that accompanies it. …

Utagaki is a place where men and women meet based on human nature and the instinct to preserve the species.
Naturally, it is a place where universal human patterns are expressed.
Throughout our long history, human beings have created opportunities for encounters as part of their culture.
The Manyoshu is said to have been founded on the basis of such “song” culture.
Songs were originally meant to be sung aloud and accompanied by a verse.
The form of “aibun” has the element of primitive confession.
In “Hanaichimonme,” the confession, “I want ◎◎chan,” is sung to the rhythm of the group’s musical accompaniment.
In the rhythm of the group’s musical accompaniment and the cheering of their voices
The formal culture of the song is to express one’s feelings honestly and without hesitation.
Even people who normally cannot express their feelings honestly
In such a formality, people who normally cannot express their feelings honestly are able to do so naturally.
In this way, the song is a formality that allows people who normally cannot express their feelings honestly to do so.
I think this is a unique wisdom of human society to maintain the prosperity of offspring.
When you say it out loud, the expression on the other person’s face comes into focus, and you can see that he or she is not surprised.
“Oh, so they’re not satisfied, huh? (laughs).
The playing of various musical instruments can also be said to create such an atmosphere.
The basis of the poetry of the Manyoshu is the culture of “sōmon,” or “hearing and hearing again.
In the Japanese communicative form, the rhythm of the five-seven-five syllable form was naturally normative.
The rhythm of the five-seven-five syllables is a natural norm in the Japanese communication system, but even before it was written down, it was still used to create a certain atmosphere.
Even before the Japanese language was written, this sense of rhyme and rhythm must have been important.
It must have had a strong appeal deep in the psyche of the Japanese people.
The Japanese have long been neighboring societies.
In Shihbaoshan, Yunnan Province, China, there are still songagaki, a traditional form of seeking a marriage partner.
Men and women exchange passionate impromptu songs for several hours.
The Tong people of Guizhou Province, China, use a riddle-like singing contest to determine the personality and knowledge of the other person.
The Tong people of Guizhou Province, China, have a tradition of singing songs that at first resemble riddles to determine the personality and knowledge of the other person.
When the person they are interested in is decided, they sing a song of oath.

It is said that the “performing arts” originated at these “utagaki” gatherings.
Utagaki became the prototype of the “city” as a place for human interaction.
As the performing arts developed, they diversified and became more sophisticated, giving rise to specialized “entertainers” with advanced skills and techniques.
The development of the performing arts also gave birth to specialized “entertainers” with sophisticated and advanced skills.
In the poetry preserved in the Manyoshu (Anthology of Myriad Leaves), scroll 16, there is a song about the “Deer Dance” as a Shinto ritual art, as well as a song that describes the appearance of crabs and deer.
In addition to the ancient performing arts of the Japanese archipelago, there are also songs about the celebration of festivals accompanied by gestures that imitate crabs and deer.
In addition to the ancient performing arts of the societies of the Japanese archipelago, the performing arts of the peninsula and the continent were also handed down.
The third photo shows a performance of the “Gigaku” from the Wu Dynasty in China, which is said to have been performed at the opening ceremony of the Great Buddha in Nara.
This exhibit at the Manyo Culture Museum shows “Gigaku” from the Chinese province of Wu.
The reality of the Asuka and Manyo periods of human social culture as entertainment.
In Japan, the “city formation” progressed in earnest from Asuka to Nara.

Food Culture and Ingredients at the Time of Manyo Asuka Historical Testimony-6
Trading fruits and vegetables in an exchange-type commerce. The V-sign is telling the price or inviting laughter? …

One of the pleasures of museum exhibits is that the “historical research” is reproduced in a visible form.
Although superficial political upheavals are studied in detail, the “way of life” of the general populace is not so easily reproduced.
but it is difficult to reproduce the “way of life” of ordinary people.
Is it a bit of a fetish to focus on such things?
The photo shows the diorama exhibit in the basement of the Nara Prefecture Complex of Manyo Culture Museum.
This is the kind of thing that makes me fall in love with it (laughs).

The setting of this diorama is a place of “Utagaki – song and music.
An old man sells vegetables, fruits, and produce, and a woman buys them.
What is surprising is that among the products traded, the sizes of “apples” and “radishes,” which are easy to understand, are very different from those of today.
The size of the apples and daikon radishes, which are easily recognizable, are quite different from those of today.
The apple is represented as a nut almost the size of a chestnut.
It seems as if it would fit in one’s mouth in one bite.
It may lack a little bit of crunchiness, but this is an interesting texture to enjoy.
However, it is an interesting texture to enjoy.
There are also some citrus-like fruits on sale, although I cannot identify the variety.
An old merchant holds up a daikon radish and introduces it to us, but we can’t help but wonder if it is a carrot.
They are so big that one might think, “Is this a carrot?
After one serving of grated daikon, it would be gone in about one serving.
It is a cute size. I wonder if grating machines are widely used in Japan.
Since they are small, they are sold in sets of 5-6 daikon grated in bundles.
I think this is how much they were usually sold for family use.
The “long green onions” displayed next to them are not much different from daikon radish.
It is remembered that they were mostly used as “condiments” for food.
The old man’s store specializes in fruits and vegetables, but fish is sold exclusively by hawkers.
Fish would have been transported to the inland Yamato Basin by river transportation, but this kind of street sales would not be able to maintain freshness.
However, the issue of maintaining freshness must have been a problem for this type of street vendor.
Beside the old man was a sturdy-looking jute bag.
The old man was flanked by sturdy burlap sacks, into which produce for sale was packed.
The street-level store was built in combination with the mushiro that made up the store’s facade.

こうした状況を受けて建築業界の「世論」がどう反応していくのか、
依然として感染症による他者非難の暴風圧があるなかでは
自由闊達な意見交換機会が再開されるまでに至っていない。
本来、国の基準更新はもっと自由な対話環境が必要ではないかとは思う。
まぁしかし、現実はこのように進行しているので対応して行く必要がある。

寒冷地では自由往来も限定され住宅関係の団体ミーティングも
ようやく6月くらいから萌芽的に再開してきている。
北海道でも来週にアース21の例会がリアルとZoomのハイブリッド開催。
新住協札幌支部の会合も「現場見学会」のみ先週開催というところ。
当然、省エネ等級更新、最上位等級7についての
自由な意見交換もまだ聞くことが出来ない。
そんななか、新住協関西支部の6月の勉強会が開催されて
久しぶりに鎌田紀彦代表理事の講演を聴講することができた。
今回の等級7基準について、それに対応する断熱手法を検討するもの。
関西支部での勉強会なので基本的には温暖地域での対応法が検討されていた。
ただ、わたし的には寒冷地1〜2地域での断熱手法に当然興味を持っていた。
徹頭徹尾、図表と数式による講演でしたが、
そのなかで寒冷地に示されていたのは図のような外壁構成。
案の上ではありますが、北海道では壁厚300mm超というのが対応法になる。
断熱材の厚みで210+100mmで、その外側に外装が施される想定。
壁厚は普通に考えれば350mm超になっていく。
単純に4間四方の16坪平面の住宅を想定すると、おおむね3坪面積相当の
断熱壁ということになる。比例で言えば100:18.75の比率。
パッシブハウスというドイツ主唱の基準は北海道ではほぼ無理筋と
一顧だにされなくなった。それが寒冷地住宅市場の常識的反応。
少なくとも都市環境・狭小敷地化が進行する最大消費地域・札幌で
外壁占有率が2割近いというのは現実的ではないという市場反応です。
人間は外壁をつくるために家を建てるのではない。
たのしく暮らすために家を建てるのであって、基準のためではない。
また鎌田先生の講演ではこの基準対応のコストアップが
かなり大幅にならざるを得ず、ユーザーの支持が得られるかどうか、
といった提起もされていた。課題の最先端地域そのもの。

温暖地の住宅性能を向上させる基準誘導には意味がある。
いま北海道で普通に建てられている断熱仕様の住宅を温暖地で建てれば
最高等級7は容易に実現する。寒冷地市場が先導して実現のコスト合理性もある。
しかし一方で、寒冷地域のユーザーはこの新基準にどう反応していくか、
かなり視界不透明ではないかという印象を持った次第。・・・

New Energy Conservation Standard, Highest Grade 7, Now in Cold Regions?
The cold region housing market has pioneered energy-saving insulation methods and achieved cost reductions through mass construction. Now, with the Grade 7 standard, we are once again at the “cutting edge of the issue. …

Amidst the social blockage caused by infectious diseases and the lack of normal communication
The Ministry of Land, Infrastructure, Transport and Tourism (MLIT) has announced new energy conservation grade standards
The Ministry of Land, Infrastructure, Transport and Tourism (MLIT) has announced new energy efficiency rating levels 6 and 7, which were also passed by the Diet.
How will “public opinion” in the building industry react to this situation?
With the storm pressure of blaming others due to infectious diseases still in place, it is difficult to know how the public will react.
The opportunity for a free and vigorous exchange of opinions has not yet resumed.
In essence, I think that the renewal of national standards requires a more liberal environment for dialogue.
Well, however, the reality is that this is the way things are progressing, and we need to deal with it.

In cold climates, free traffic is limited and housing-related group meetings are not being held.
Finally, meetings of housing-related organizations have begun to sprout from around June.
In Hokkaido, the Earth 21 meeting will be held next week as a hybrid of real and Zoom.
The Shinjyukyo Sapporo Chapter also held a “site tour” only last week.
Naturally, the free exchange of opinions on the renewal of the energy efficiency rating, the highest rating of 7, has yet to take place.
The New Jyukyo Kansai Branch is also holding a hybrid meeting of real life and Zoom.
In the meantime, the June study meeting of the Shinjyukyo Kansai Branch was held.
I was able to listen to a lecture by Representative Director Norihiko Kamata for the first time in a while.
The lecture was about the new Grade 7 standard and the corresponding heat insulation methods.
Since it was a study session of the Kansai Branch, basically the methods to be used in warm regions were discussed.
However, I was naturally interested in the insulation methods for the first two cold regions.
The lecture was based entirely on charts and mathematical formulas.
In the lecture, he showed the exterior wall configuration for cold regions as shown in the figure.
Although it is just a suggestion, in Hokkaido, the corresponding method is to have a wall thickness of over 300 mm.
It is assumed that the thickness of the insulation is 210 + 100 mm, and the exterior is applied on the outside of the insulation.
The wall thickness would normally be over 350mm.
Assuming a simple 4-ken square 16 tsubo flat house, this means that the insulation wall is equivalent to an area of approximately 3 tsubo.
It means that the insulation wall is equivalent to about 3 tsubo area. The ratio is 100:18.75.
The German standard of “passive house” is now considered to be almost impossible in Hokkaido.
The German standard of “Passive House” is no longer considered a viable option in Hokkaido. This is the common-sense reaction of the cold-region housing market.
At least in Sapporo, the largest consumption area in Japan, where the urban environment and small lot sizes are progressing, the percentage of exterior walls occupied by houses is close to 20%.
The market reaction is that an exterior wall occupancy rate of nearly 20% is unrealistic, at least in Sapporo, the largest consumption area in Japan, where urban environments and small lot sizes are progressively being developed.
People do not build houses to build exterior walls.
They build houses to live happily, not for the sake of standards.
In addition, Dr. Kamada’s speech showed that the cost increase to comply with this standard would have to be quite large, and that the support of users would be very important.
The cost increase to comply with this standard would have to be quite large, and he wondered whether he would be able to gain the support of users.
The area itself is at the forefront of the issue. The region itself is at the forefront of the issue.

It is meaningful to induce standards that improve housing performance in warmer regions.
If houses with insulation specifications that are commonly built in Hokkaido are built in warmer regions, it is easy to achieve the highest grade 7.
the highest grade 7 can be easily achieved. The cold-region market is leading the way, and there is cost rationality in achieving this.
On the other hand, however, I have the impression that users in cold regions may not be so sure about how they will react to the new standard.
I have the impression that the market in cold regions is not very clear. …

Asuka Historical Testimony – 5] “Blacksmithing Workshop,” a Technological Force at the Beginning of the Nation
Metalworking “industrialization” was essential for a nation to grow into an archipelagic society. Resources and energy are the universal historical factors of mankind. …

Yesterday, I considered the Asuka Great Buddha, a concrete metalworking artifact and its production.
The progress and development of a civilization is
The progress and development of a civilization is driven by something unusual and sparkling as a catalyst.
In the Asuka period, the original period of the Japanese nation, Buddhism played a leading role in the “modernization idea.
Buddhism was the one that “stuck” in the hearts of the 8 million nature-worshipping peoples.
In the extreme, the role played by Buddhist statues and metalwork is immeasurable.
In contrast to the local power that existed in each region of the archipelago as eight million people, the central power structure
The technical power of metalworking functioned as an immediate power to control and subjugate them as a central power structure.
The metalworking technology must have functioned as an immediate power to control and subjugate them as a central power structure.
In order to show off their legitimacy, the local authorities had to
It was a necessary incentive for each regional power to make its strong ties to the central
This must have been a necessary motive.

The photo is from the exhibition at the Nara Prefecture Complex of Manyo Man’yo Culture Museum, which stands on top of the Ikegakobo site.
From the Asuka Pond Studio site, gold grains, gold leaf, silver fragments, and other items that appear to have been melted down into gold and silver were found.
The crucible in which the gold and silver were melted was found at the Asuka Pond Studio site, confirming the processing of gold and silver.
Glass, which was thought to be jade, was also excavated.

The excavation of the crucibles suggests that a large amount of gold and silver was handled.
What is silver, gold, and jade, but a treasure so great, that it may be passed on to a child?
This famous poem by Yamakami Imura may be evidence that he was familiar with the production process in Asuka.
At that time, gold was not produced domestically, but was brought to Japan via Korea.
Silver may have been domestically produced.
Ironware began to be used in Japan from the Yayoi period. They were introduced from the continent and peninsula.
They were widespread throughout the country during the Kofun period.
Paddy field cultivation probably started in the beginning by looking for “Ashiwara no Nakatsu” (the middle of Ashiwara).
Gradually, the best sites in such natural conditions were exhausted.
After that, the land was expanded to areas where cultivation and civil engineering with iron tools were indispensable.
As they did so, more powerful skis and spears became a necessity.
Among the iron artifacts excavated at the Asukaike workshop, the most frequently found item was a spike.
Other basic building materials include kasugai, chisels, taganes, and sword hammers.
The emergence of reinforcing hardware for joints, which exceeded the limits of the previous method of weaving and binding wood fibers, led to the development of the construction method.
The emergence of reinforcing hardware for joints that exceeded the limits of the wood-fiber weave-and-bind method led to the realization of larger, multi-layered buildings.
Since iron was not produced in the archipelago, the maintenance of interests on the Korean peninsula was an essential “life force” for the kingship of the archipelago.
This became an indispensable “lifeline” for the royalty in the archipelago, and eventually became a foreshadowing motive for direct involvement, such as the invasion of the Hakuchon River.
This became a foreshadowing motive for direct involvement.
Later, iron mines began to be developed in the San’in region, and
The discovery of mineral deposits in various parts of the country, and at the same time, the large amount of forest resources surrounded by the sea
biomass resources essential for iron production. Since then
By the end of the Edo period, almost all the mountains in the country were developed to the extent that they were turned into “bald mountains.
The Edo Shogunate frequently issued decrees to protect forests, such as the “Maeyama (mountain retaining)” ordinance.
In the end, these resource-energy transitions can be said to have played a leading role in Japanese history.

The same is true of human history in general.
In archipelagic societies, architecture developed not from stone but from wood.
However, the increasing size and mass production of architecture during the Nara period led to the depletion of natural resources, and the development of wooden architecture in the early Kamakura period led to the development of the Great Buddha in Nara.
The large size and mass production of buildings during the Nara period (710-794) led to the depletion of resources, and the reconstruction of the Great Buddha Hall in Nara in the early Kamakura period (1185-1333) required the use of timber from Yamaguchi Prefecture.
Asuka Ike Kobo is the starting point of metalworking, industry, and architecture in Japan.
The Asuka Pond Studio vividly conveys the conditions of the early days of metalworking, industry, and architecture in Japan.
