昨日は新住協北海道の数年ぶりのリアル地区大会。
18-19の両日日程が組まれていましたがわたしは別件での先約があって
18日はどうしてもムリで、19日もここ１年以上取り組んできた業務の中締め。
やむなく欠席の予定でしたが、昨日の朝、わが家周辺の「発寒川緑地」散歩中に
ご近所住まいの道総研理事・鈴木大隆さんとバッタリ。
・・・って、なぜか氏の愛犬との相性がいいのか、不思議と出会う（笑）。
で、日中は鎌田紀彦先生との「対論」が日程予定されているのも知っていたので
「いや〜、きょうはお疲れさまです・・・」となにげにあいさつ。
そこから相性のいいイヌと連れだって散歩会議。
わたしは鈴木さんが座長を務められている北海道の「北方型住宅」諮問会議の
メンバーとしてながく参加させていただいているご縁もあるので
今回の「北方型住宅ZERO」の策定にあたっての企画経緯なども情報共有しています。
鎌田先生が領導される新住協という日本の住宅性能運動の中核と、
きょうがその最初の接点になる、ということでの心理的な微妙な緊張感。
とくに鈴木さんは鎌田紀彦先生の弟子という立場とはいえ、
同じ「住宅性能」論領域では立場的に意見に違いが出てくることもある。
そうした部分が伝わってきて、そうか、と頓悟しまして、
わたしは先約の会合についてはスタッフに任せることにして
急遽、新住協大会に参加してみることにした次第です。
まぁ別になにができるわけでもないけれど、場合によっては憎まれ役くらいは
お鉢が回ってくるかも知れないというところ（笑）。

ということで案の定、鈴木さんの講演中から鎌田先生からの「質問」多数。
それも日本の住宅性能の推移の核心に迫る論議内容。
また鈴木さんから建築行政のたくさんの背景的情報などもあって、
師弟の間のかなり白熱した論議内容が開示されていました。
「これはちょっと住宅工務店向けの内容を超えているのでは・・・」と
わたしとしては興味津々の部分でもあったのですが、急遽申し込んだので
席は一番最後の方で語尾が正確には聞き取れませんでした、としておきます。
しかし論議は白熱したけれど、２枚の図で示したナカミ、
具体的に２枚目の鎌田先生の北海道の住宅のミライとして示したエネルギー目標と
３枚目の「北方型住宅ZERO」のポイント制という制度設計について
ハッキリとした方向性の同意一致が確認されたと思います。
鎌田先生からは各ポイント制の詳細内容については吟味が必要だけれど
先生自身もかねてからユーザー理解も含めてポイント制が
いちばんわかりやすく実践的だという判断が示されていました。
これはReplan誌面での連載記事でもかねてからそのような記述が表現されています。

ということで論議内容の概要の概要みたいですが（笑）
やがて新住協北海道支部から内容の詳細解説が発出されることを期待します。
あ、ときどき前振りでわたしの名前が使われた程度で
「実はあいつが悪い」みたいな展開は辛うじて免れホッといたしました（笑）。

Norihiko Kamada – Hirotaka Suzuki Dialogue
A dialogue between two people who are at the core of improving housing performance in Japan. Beyond a heated debate, the two men move on to resonate with the framework of “Northern-style housing ZERO”. Norihiko Kamada

Yesterday was the first real regional convention of Shinjyukyo Hokkaido in several years.
The schedule was set for the 18th and 19th, but I was unable to attend on the 18th due to other commitments.
I was unable to attend on the 18th due to other commitments, and on the 19th, I had to close out the work I have been doing for more than a year.
I had no choice but to miss the meeting, but yesterday morning, while taking a walk in the Hassamu River greenbelt near my house, I met a friend of mine who lives in the neighborhood, the president of the Hokkaido General Assembly.
I bumped into Mr. Hirotaka Suzuki, Director of the Hokkaido Research Institute, who lives in the neighborhood.
I wondered why he and his dog were so compatible with each other (laugh).
I knew that he was scheduled to have a “discussion” with Dr. Norihiko Kamata during the day, so I said to him, “Oh no, I’m so tired today.
I casually greeted him by saying, “Well, thank you for your hard work today….
From there, I went for a walking meeting with my dog, with whom I have a good rapport.
I have been a member of the Advisory Council for “Northern-style Housing” in Hokkaido, chaired by Mr. Suzuki.
I have been a member of the Hokkaido “Northern Housing” Advisory Council, chaired by Mr. Suzuki, for a long time.
I also share information about the planning process of the “Northern Style Housing ZERO” project.
Today is the first point of contact between the core of the Japanese housing performance movement, Shinjyukyo, led by Mr. Kamata, and the “Northern Housing ZERO” project.
I felt a subtle psychological tension because today is the first point of contact with the core of the Japanese housing performance movement, the New Jyukyo, which is led by Mr. Kamata.
Especially, Mr. Suzuki, even though he is a disciple of Dr. Norihiko Kamata.
Although Mr. Suzuki is a disciple of Mr. Norihiko Kamata, there are differences of opinion in the same area of “housing performance” from a standpoint.
I was able to get a sense of this, and I am glad to hear it.
I decided to leave the matter of the meeting to my staff.
I decided to attend the New Residential Association Convention.
Well, it’s not that I can do anything, but I might be asked to play a role
I was not really able to do anything, but I might be asked to play a role in some cases (laugh).

As expected, Mr. Kamata asked many questions during Mr. Suzuki’s lecture.
The content of the discussion went right to the heart of the transition of housing performance in Japan.
Mr. Suzuki also provided a lot of background information on building administration.
The content of the heated discussion between master and disciple was disclosed.
I was curious about some of the content, saying, “This is a bit beyond the scope of a residential construction company…”
I was also very interested in the discussion, but I had to rush to attend the meeting.
However, since I had to rush to attend the meeting, I was seated at the very end of the table and could not hear the end of each word correctly.
The discussion was heated, but I could not understand what was going on in the Nakami shown in the two diagrams.
Specifically, the energy target shown by Dr. Kamata on the second page as “Mirai” for housing in Hokkaido, and the energy target on the third page as “Northern-style housing” for housing in the northern region.
The third one is the point system design of “Northern-style house ZERO”.
I believe that we were able to confirm a clear agreement on the direction of the project.
Dr. Kamata said that although the details of each point system need to be examined, he himself has long been aware of the importance of users’ understanding.
However, Dr. Kamada himself has long been of the opinion that the point system, including user understanding, is the easiest and most practical to understand.
Dr. Kamata himself has long expressed his judgment that the point system is the easiest to understand and the most practical, including the understanding of users.
This has also been expressed for some time in his serial articles in Replan magazine.

So this sounds like an overview of the content of the discussion (laughs).
I hope that the Hokkaido branch of Shinjyukyo will soon issue a detailed explanation of the contents.
I hope that the Hokkaido Branch of the New Jyukyo will soon issue a detailed explanation of the contents.
I am relieved that I was not used as a preface to the article, and that I was not used in any way that would make it sound like “Actually, it was his fault” (laugh).

いろいろと論議の多い公共放送NHKであります。
国鉄は民営化されたけれど、もっと巨大な問題組織であるNHK、
あるいは国民共有財である電波利用を許認可で得ているに過ぎない民間放送が
さまざまな問題を起こしているのに既存メディアではスルーされている問題。
菅政権ではそうした改革が進む方向性が示されていたけれど
いまの政権からは、どういう政策を実現したいのか見えてこない。・・・

というところですが、個人的にはNHKのBSのニッチテーマ番組は好き（笑）。
民間ではコスパが悪く放送できない興味深い番組が放送されることがある。
先日カミさんが「きっと面白いと言いそうだから」と録画していてくれた番組。
「松下奈緒 聖徳太子1400年への旅」という番組で9/28に放送されていた。
先日法隆寺宮大工・西岡常一さんの弟子・小川三夫氏の講演取材を書きましたが
法隆寺古建築についての時代背景や存続してきた状況の掘り起こしテーマ。
ということでチェックして見たら非常に面白い内容に触れていた。
なんと、千年を超える世界最古の木造建築として歴世の改修履歴があり
小屋組の補強として今で言う「プレカット規格材」が使われていたと言う内容。
法隆寺は飛鳥時代、聖徳太子が建立した本格的国家公共事業・仏教建築。
四天王寺や飛鳥寺などが火災被害で後世に建て替えられたのに対して
創建間もなく一度火災消失したけれどその時点での再建以降、
今日まで世界最古の歴史を刻んできている、日本人のこころのシンボル。
このように長い歴史を刻んできたのにはそれこそ歴世の大工たちの
心魂を傾けた存続努力があったことは誰にもわかる道理。
考えて見ると法隆寺というのは建築「リフォーム」の象徴とも言える。
現代のリフォームはひたすら世界共通デザインに帰依しているけれど
日本の匠たちは原形デザインにリスペクトするこころを持ち続けてきた。
先日聞いていた小川三夫氏の講演でも、長期時間的荷重を受けて構造補強を
繰り返してきた様子をお話しされていたけれど、
聖徳太子没後、国家建築から一民間建築になっていた段階で維持管理には
ひと筋ではない苦難の経緯もあったとされていた。
今回の番組では、奈良期以降に施された構造補強の解析が説明され
26×21cmの統一的規格材が小屋裏各所に使用されている状況の活写。
番組では、創建時には各部位の材もそれぞれ独自の太さ・厚みの材が使われたが
法隆寺の経済的困窮を反映して規格材が使われていたのでは、という視点構成。
しかしわたし的には、構造補強材であり各部位での微妙な劣化変位を調整するには
一定寸法の部材の方が大工側としては合理的だったのではないかと思えた。
どうやって強度補強するかと考えたとき、
部材は一定寸法の方が現場対応しやすいのではないかと思えたのですね。
法隆寺宮大工も1400年間にはいろいろな「工夫」を考えたに違いない。
小川さんの言では大工の数だけ、手法に違いは出る、
要は木組みのクセを読み、最適な手法を発見するのが肝要ということではないか。
規格材という発想もむしろ合理主義と構造強化現場対応を表現している。

先人の「合理主義」の実証が垣間見えたようで、
非常に面白く拝見していた。・・・もうちょっと合理的にはして欲しいけれど
わたし、NHK料金はきちんと納入しております（笑）。

Horyu-ji Temple Pre-cut Lumber Used to Reinforce Timber Framing
A symbol of proud architectural renovation. The use of standardized dimensions was adopted for economic reasons, but the unification of lumber is rational for structural reinforcement. …

NHK is a highly controversial public broadcaster.
The Japanese National Railways (JNR) has been privatized, but NHK, an even larger problematic organization, or private broadcasting, which is merely licensed to use the public’s common property, the airwaves, is not.
Or private broadcasters who only have a license to use the public’s common property, the airwaves, are causing all sorts of problems that are not being addressed by the existing media.
The Kan administration is making progress in such reforms.
The Kan administration showed a direction for such reforms, but the current administration has not yet realized what policies are needed.
The current administration does not seem to have a clear idea of what kind of policies it wants to achieve. I am not sure what kind of policies the current administration is trying to achieve.

Personally, I like NHK’s BS niche theme programs (laugh).
Sometimes they broadcast interesting programs that cannot be aired in the private sector due to poor cost performance.
The other day, my wife recorded a program that she thought I would find interesting.
It was called “Nao Matsushita: A Journey to the 1,400th Anniversary of Prince Shotoku” and was broadcast on September 28.
The other day, I wrote about a lecture by Mitsuo Ogawa, a pupil of Tsunekazu Nishioka, a carpenter of Horyuji Temple.
The theme of the program is to dig up the historical background and the situation that has survived about the ancient architecture of Horyuji Temple.
So I checked it out and saw that it touched on a very interesting subject.
To my surprise, there is a history of renovation in successive generations as the world’s oldest wooden building over 1,000 years old
The content said that “pre-cut standard lumber,” as it is called today, was used to reinforce the hut assembly.
Horyu-ji Temple was built by Prince Shotoku during the Asuka period (710-794), and was a full-scale national public works and Buddhist architecture.
While Shitennoji Temple and Asukadera Temple were rebuilt in later periods due to fire damage, Horyuji Temple was destroyed by fire once soon after its construction.
The temple was destroyed by fire shortly after its construction, but since its reconstruction at that time, it has been the oldest building in the world to this day.
It is a symbol of the spirit of the Japanese people.
The reason for this long history is due to the efforts of successive generations of carpenters who have devoted their hearts and souls to the preservation of the temple.
The reason why Horyu-ji Temple has carved out such a long history is obvious to anyone who knows.
Horyu-ji Temple is a symbol of architectural “renovation.
Modern renovation has been relying solely on universal design.
Japanese craftsmen have kept the spirit of respect for the original design.
In a lecture given by Mitsuo Ogawa the other day, he talked about how he has repeatedly reinforced the structure under long-term loads.
He also talked about how he repeatedly reinforced the structure under long-term loads.
After the death of Prince Shotoku, the building was transformed from a national building to a private building.
However, after the death of Prince Shotoku, the building was transformed from a national building to a private one, and there were some difficulties in its maintenance.
In this program, an analysis of the structural reinforcement applied after the Nara period was explained.
The program also showed the use of 26 x 21 cm standardized lumber in various parts of the back of the building.
The program also explains that at the time of construction, each part of the building was made of its own thickness and thickness, but that this was not the case at the time of Horyuji’s economic hardship.
However, I think that the standardized lumber may have been used to reflect the economic difficulties of Horyuji Temple.
However, in my opinion, it is better to use a material of a certain size for structural reinforcement and to adjust for subtle deterioration and displacement in each part of the structure.
I think it would have been more reasonable for the carpenters to use members with fixed dimensions.
When I thought about how to strengthen and reinforce the structure
I thought that it would be easier to deal with the members of a certain size at the site.
The carpenters of the Horyuji Palace must have thought of various “devices” during the 1,400 years of their construction.
Mr. Ogawa says that as many carpenters as there are, there will be differences in their methods.
In short, it is important to read the peculiarities of woodworking and find the most appropriate method.
The idea of standardized lumber is also an expression of rationalism and on-site response to structural reinforcement.

It seemed as if I caught a glimpse of a demonstration of our predecessors’ “rationalism.
It was very interesting to watch. I wish they would be a little more rational, but…
I have been paying my NHK bill properly (laugh).

昨日今日２日間は北海道が会場になっての国の住宅月間の中央イベント開催。
その一環としての岩見沢市での大工技能関連の催事に取材参加。
さきに「削ろう会」を見学して来ましたが、こちら詳細は明日以降に。
夕方からは鵤工舎・小川三夫氏講演・対談会に参加していました。
氏は、法隆寺宮大工・西岡常一さんの弟子。
西岡氏は法隆寺の昭和の改修工事に取り組んでいたが、
工法を巡って国の諮問機関「建築工学博士」たちから構造補強のために
金物補強すべきであるという方針指示を受けた際に
「打ち首にされても、そんなことはできない」とその方針を拒否したとされる。
いわば魂の部分でのその「正嫡」と言える存在が小川氏。
お話しからはまさに西岡さんの魂魄を身を以て受け継いでいる気迫が伝わる。
「宮大工は社寺仏閣専門であり、家を建てる家大工とは流れが違う」
「しかし、手業・魂魄としては同じ」というのが氏の考え。
北海道で家大工として技術の存続継承に強い思いを持つみなさんが参集された。

木と向き合って体で関わっていく大工仕事は内語しながらの営為。
体技としての大工技能については当方には素養は無く
その精神性の部分を共有するよう内語で翻訳しながら対話していた。
自分たちのそれぞれの仕事領域で経験する内語と比較しながら、
働くということの本質について対語することになるのが自然でしょう。
体技習得とは労働基準法みたいな社会制度とはモノサシが違う。
心得という本質部分ではそうであることは伝わってくる。
そしてそれは「日本のものづくり」の本質部分の解析でもあると思われた。
いま日本の円安が進行しているけれど、ある意味では
世界の資本主義からのサインとして世界の製造業の中心に
日本が復活すべきであると後押しされているようにも思える。
事実、いろいろな企業分野で日本に製造拠点を復元させる動きがある。
半導体の製造拠点が九州に作られたり、アイリスオーヤマが中国から撤退して
日本国内で製造ラインを再構築するという発表。
自動車企業でも中国の生産ラインをまったく区分けしてその他の世界で
生産ラインを独自に生成する取り組みが活発に展開してきている。
報道される事象をはるかに超えてこうした動きは加速しているのだろう。
戦後日本の復興はものづくり製造業が世界の需要の追い風を受けたものだった。
そういう現在認識のなかで小川氏の講演・対談は視点価値があると思われた。
課題はたくさんある。
会場からの声では「ひとづくり」教育現場での現状に絶望した悲嘆的発言も。
しかし、わたし的には日本の大工体技伝統に象徴される魂魄のコアな部分が
社会全体に根付いていることを信じたいと思います。
魂魄の部分でのものづくりパワーは
日本人の意識の底流に根強くあり続けていると信じて取り組んでいくしかない。

労働基準法のような枠組みは受容した上で、魂魄は根太く継承していく。
そう考えていくことで世界の中で「ものづくり大国・日本」は生き残れる。
そんな内語・期待感を反芻しながら帰路に着いていた。

What is the “Inheritance of Physical Skill”? Lecture and discussion by Mitsuo Ogawa, a member of the Japanese Manufacturing Industry]
The current depreciation of the yen is a tailwind for Japan’s manufacturing industry. In fact, the manufacturing industry is making a comeback in many business fields. Let us consider the spirit of monozukuri. ……

Yesterday and today, Hokkaido was the venue for the central event of the national housing month.
As part of the event, I covered a carpentry-related event in Iwamizawa City.
I visited the “Shirouki-ro-kai” (cutting workshop) earlier, but I will give you more details tomorrow.
In the evening, I attended a lecture and discussion with Mitsuo Ogawa of Ikaruga Kosha.
Mr. Ogawa is a disciple of Tsunekazu Nishioka, the master carpenter of Horyuji Temple.
Mr. Nishioka was working on the Showa renovation of Horyuji Temple.
He was working on the renovation of Horyuji Temple in the Showa period (1926-1989), when he received a directive from the national advisory body for structural reinforcement from “doctors of architectural engineering.
When he was instructed by the government’s advisory body, “architectural engineering doctors,” to reinforce the structure with metal reinforcement, Nishioka said
He is said to have rejected this policy, saying, “Even if I am beheaded, I cannot do such a thing.
Mr. Ogawa is the “legitimate heir” of Mr. Nishioka’s soul, so to speak.
His speech conveys the spirit of Mr. Nishioka, who has inherited his spirit and soul through his own body.
He said, “Shrine carpenters specialize in shrines, temples, and Buddhist temples, which is different from the process of house carpenters who build houses.
However, the handiwork and spirit of the carpenters are the same.
The participants were all carpenters in Hokkaido who have a strong desire to continue their skills as house carpenters.

Carpentry, which involves facing the wood with one’s body, is an activity done while speaking internally.
I have no background in carpentry skills as a physical skill.
We were talking to each other, translating in our own language so that we could share the spirituality of the work.
We were comparing the internal language of our own work with the internal language we experienced in our respective fields of work.
It would be natural to have a dialogue about the nature of work.
Physical skill acquisition is not the same thing as a social system like the Labor Standards Act.
It is conveyed that it is so in the essential part of “Kokoro Gakushu”.
And it seems to be an analysis of the essence of “Japanese monozukuri.
The yen is weakening in Japan, but in a sense, it is a sign from the world capitalism that the world’s manufacturing system is not the same as Japan’s.
It is a sign from the world capitalism that Japan should revive its position at the center of the world’s manufacturing industry.
Japan should revive its position as the center of the world’s manufacturing industry.
In fact, there is a movement to restore manufacturing bases in Japan in various business fields.
There have been announcements that semiconductor manufacturing facilities will be built in Kyushu, that Iris Okayama will withdraw from China and rebuild its manufacturing lines in Japan, and so on.
Iris Okayama has announced that it will withdraw from China and rebuild its manufacturing line in Japan.
Automobile companies are also moving to create their own production lines in other parts of the world by completely separating their production lines in China from the rest of the world.
The trend is far beyond what is reported in the media.
These developments are probably accelerating far beyond what is reported in the media.
Japan’s postwar revival was a result of the manufacturing industry benefiting from a tailwind of global demand.
In this context, I thought Mr. Ogawa’s lecture and discussion were worthwhile.
There are many issues to be addressed.
Some in the audience expressed despair over the current state of “human resource development” in the field of education.
However, I would like to believe that the core of the spirit symbolized by the Japanese carpentry tradition has taken root in the society as a whole.
I would like to believe that the core of the spirit and soul symbolized by the Japanese carpentry tradition has taken root in the society as a whole.
The power of monozukuri in the spirit of the soul is
We have no choice but to work on it, believing that it continues to be deeply rooted in the undercurrent of the Japanese people’s consciousness.

While accepting a framework such as the Labor Standards Law, the spirit of monozukuri must be passed on from generation to generation.
By thinking in this way, “Japan, a manufacturing powerhouse,” can survive in the world.
I was on my way back home, ruminating on such internal words and expectations.

日本列島に残る旧石器時代人の痕跡・遺跡からの時代相探索。
時間にして37,000年前から縄文開始の約13,000年前まで
25,000年間くらいの時代相が相当する。
人間の世代更新をおおまかに20才として考えれば、1,250世代。
ジオラマのような親子の知恵の継承が不断に行われ続けた。
石器へのさまざまな工夫をもって人類は生き抜いてきた。
ちょうど子どもが石に向かって鋭利な注意力を向けている様子。
それを見つめる父親の表情になんともいえない感情がこもっている。

「この石、こんなふうに割れるんだ。この断面なら、こう使えるかなぁ」
「ようやくこいつも石器の向上に注意を持ち始めたか・・・」

石に向かって自分たちの生き方を進歩させる工夫を凝らす。
もっとも普遍的に存在する利器としての石を
道具にしていくという飛躍とその発展ぶりにこそ、
人類進化のさまざまな「要素」が発現していったのでしょう。
その要素が「止揚」されて現代世界にまで技術痕跡として繋がっている。
これは確実に存在した歴史事実。
イラスト表現では「直接打撃・間接打撃・押圧剥離」という技術手法解説。
人間という動物種が知恵というものを進化させたルーツ。
生き延びてくる中でいっときも休むことなく繰り返された営為。
「その割れ方はな、こうやればできるんだぞ」
「そうなんだ、でもこうやったらもっと良くないかなぁ、父ちゃん」
「おお、そういうのもアリだなぁ・・・」
たぶん進化のプロセスはこういう会話からだったのだろう。
こういう親子対話が1,250世代にわたって繰り返された結果、
進化プロセスが飽和沸点を超えて、時代画期として縄文の世が始まった。

道具を使ってより暮らしやすい環境を現実世界で実現する。
それまでの動物種にはみられない特殊な発展が人類だけに可能になった。
この石器の進化は同時代的に世界各地で進行して
やがてカミソリ状の鋭利な石器を組み合わせる細石刃文化に極まっていく。
石器時代の「最先端技術」。
この文化はシベリア・中国北部・朝鮮半島・日本列島と周辺全域に広がった。
列島での嚆矢は25,000年前頃、大陸と地続きだった北海道にやってきた。
以降その文化は広く日本列島に伝播していったとされる。
発展に当たって北海道白滝村地域の世界最高レベルの純度の黒曜石が
最高の原料とされ、その発掘生産のための社会組織的痕跡まで見られる。
「これメッチャいいべや〜、みんな欲しがるに違いない」
「こりゃぁ発掘の専門組織や、製品化の場所も必要だな・・・」
というような分業化の痕跡が見られるのだという。
世界規模での情報共有が相当の速度で伝わったことが推認される。
まさに道具の進化は情報交流の進化ももたらしたのだろう。
先人たちの生き抜く知恵に圧倒される。・・・

The History of Human Evolution in Stone Tools: The 37,000-Year History of the Japanese Archipelago – 9
The Stone Age’s most advanced technology, the “fine stone blade culture. Optimization of use brings about social development. Wide-area distribution and the development of information technology also progressed. The Stone Age

A search for chronological phases from the traces and remains of Paleolithic man in the Japanese archipelago.
From 37,000 years ago in time to about 13,000 years ago at the start of the Jomon period.
This corresponds to a period of about 25,000 years.
If we assume that the human generation renewal is roughly 20 years old, it is 1,250 generations.
Like a diorama, the wisdom of parents and children continued to be passed down from generation to generation.
Humans have survived through various innovations in stone tools.
A child is just turning his sharp attention toward a stone.
The father’s expression as he gazes at the child is filled with indescribable emotion.

The father’s face is filled with indescribable emotion as he looks at the stone. I wonder if this section can be used like this.
Finally, he is beginning to pay attention to the improvement of stone tools…”

They devise ways to advance their own way of life toward the stone.
The stone as the most universally existing useful tool.
The leap of turning stone into a tool and its development is what
The elements of human evolution were expressed in the leap and development of using stone as a tool.
These elements have been “sublimated” and connected to the modern world as technological traces.
This is a historical fact that has certainly existed.
In the illustration, the technical technique of “direct blow, indirect blow, and pressure peeling” is explained.
The roots of the evolution of wisdom in the animal species called human beings.
An activity that has been repeated without a moment’s pause in the course of survival.
You can do that cracking by doing it like this.
“Yes, but wouldn’t it be better this way, Dad?”
“Oh, that’s a good idea…”
Perhaps the evolutionary process began with these conversations.
After 1,250 generations of this kind of parent-child dialogue, the evolutionary process has reached a saturation boiling point.
The evolutionary process reached a saturation boiling point, and the Jomon period began.

We use tools to create a more comfortable living environment in the real world.
This special development, not seen in previous animal species, was possible only for humans.
This evolution of stone tools proceeded contemporaneously in various parts of the world.
This evolution of stone tools progressed contemporaneously in many parts of the world, eventually culminating in the fine stone blade culture, which combined razor-sharp stone tools.
This was the “cutting edge technology” of the Stone Age.
This culture spread throughout Siberia, northern China, the Korean peninsula, the Japanese archipelago, and surrounding areas.
The first pioneering example of this culture in the archipelago came to Hokkaido, which was connected to the continent around 25,000 years ago.
Since then, the culture is believed to have spread widely throughout the Japanese archipelago.
The world’s purest obsidian from the Shirataki Village area of Hokkaido was considered the best raw material for the development of the culture.
The obsidian found in the Shirataki Village area of Hokkaido was considered to be the best raw material, and there are even traces of the social organization that was involved in its excavation and production.
This is so good, everyone will want it.
“This is great, everyone will want it…” “We need an organization specializing in excavation and a place to commercialize it…”
We need an organization specializing in excavation and a place to commercialize the product….
It can be inferred that information sharing on a global scale was transmitted at a considerable speed.
The evolution of tools must have brought about the evolution of information exchange.
I am overwhelmed by the wisdom of our ancestors to survive. The wisdom of our ancestors to survive is overwhelming.

石器時代は動物の狩猟が基本生業であり、生産物確保手段。
日本列島各地にたくさんの遺跡が遺され、
社会としては集落もあり、それぞれの間での交易も活発に展開した。
しかし基本生業が狩猟である以上、その社会密度は対象の絶対数に依存する。
日本旧石器学会が2010年に集計した遺跡データベースによると、日本列島では
旧石器時代と縄文時代草創期の遺跡/文化層の総計は16771。内訳としては
旧石器時代14542と縄文時代草創期2526となる。 重複文化層を１遺跡として
遺跡単位で数えると旧石器時代遺跡が10150、縄文時代草創期遺跡が2432。
およそ22,000年期間の旧石器、13,000年期間の縄文と考えれば、
遺跡の数自体は旧石器遺跡の数は多いと言える。
しかし社会的生産手段の人口維持力を考えれば、集住に適した縄文と
より広域展開が必要だった旧石器というように対比できるのだろう。
現代人はすでにこういう狩猟の経験知、能力を喪失しているが、
たぶんまったく違う能力に「止揚」されて保持しているのだろう。

イラストとジオラマで槍投げでの捕獲と落とし穴猟を比較して考えて見る。
槍での捕獲というのは確率的にどうなのだろうかと思われる。
射手の腕という非科学的な要素で生産効率が左右されざるを得ない。
また獲物の側でも、なんどか危地を脱すると経験知が向上して
より対人類で安全側行動に学習していく可能性が高いと思われる。
「こないだ、仲間がやられたから、もっと注意しよう」と。
一方で落とし穴猟については、より計画的な狩猟が可能だったように思える。


図で示されているように獲物動物の群を人間集団が追い込んで
定置的に待ち伏せすることで、生産効率は高まったのではないか。
またあきらかに個人技の世界から集団知能の世界に地平が変化した。
より戦略的、計画的な知能発達が促進されたのではと思われる。
このあたりの社会的経緯について説明開示されてはいなかった。
言ってみれば「だましのテクニック」だが、こういう動物心理を見抜いて
それを先回りしてコントロールする「工夫」は同時に
対人関係へも応用利用されていったことが容易に考えられる。
社会を操作する知的快感・悪だくみに目覚めるきっかけとして機能したかも。

まぁ、この間37,000年だから類としての知能向上、DNA進化がどれほどかは
よくわからない。しかし現生人類史から言えば半分程度の時間ではある。
この間でどのように進化したのか、その内容はぜひ確認したいと思う。
現生人類の出アフリカはおおむね7-8万年前とされるけれど、
それと対比してもこの列島での経験知蓄積は相当長期だと言えるのでしょう。
そして進化の過程に日本列島の地域性ということも大きく関与した可能性。
一方で、人類は交易を通して相当広範囲に進化を共有したと考えられる。
現実に黒曜石のような鋭利で利用性の高い素材は広範囲に流通した。
そうした情報共有には具体的には「分業」のような機能が働いたかどうか、
交易者というような存在が専門的に知恵の共有に役立ったか。
どんどんと疑問と興味の規模が拡大して止まらない（笑）。・・・

Throwing Spears and Pitfalls The 37,000-Year History of the Japanese Archipelago – 7
The evolution of technology in the Stone Age occupation of hunting. Pitfall hunting brought advanced “deception” techniques and became the basis of “psychological manipulation” technology? …….

In the Stone Age, hunting animals was the basic livelihood and means of securing products.
Many archaeological sites have been found throughout the Japanese archipelago.
There are many archaeological sites throughout the Japanese archipelago, and as a society, there were settlements, and trade between them developed actively.
However, since hunting is the basic occupation, the social density of the society depends on the absolute number of the target population.
According to the archaeological site database compiled by the Paleolithic Society of Japan in 2010, in the Japanese archipelago
The total number of Paleolithic and Pioneer Jomon Period sites/cultural strata is 16771, broken down as follows.
Paleolithic 14542 and Jomon Period 2526. If the overlapping cultural layers are counted as one site, the total number of sites per cultural layer is
The Paleolithic period is 10150 sites and the Jomon period is 2432 sites.
If we consider the Paleolithic period of approximately 22,000 years and the Jomon period of 13,000 years, then the number of sites itself is about the same as the number of Paleolithic sites.
The number of Paleolithic sites itself can be said to be large.
However, considering the ability of the social means of production to sustain a population, the Jomon, which was suited to residential concentration
The Jomon, however, had a social means of production and population maintenance, and the Paleolithic required a wider area of development.

Modern humans have already lost the ability and experience to hunt.
Perhaps they have been “sublimated” into a completely different ability and retained.
Let’s compare spear-throwing and pitfall hunting in the illustration and diorama.
One wonders about the probability of capture by spear.
The production efficiency must be affected by the unscientific factor of the archer’s skill.
Also, on the part of the prey, if it escapes from danger several times, its experiential knowledge will improve, and it will be more likely to act on the safe side with humans.
It is highly likely that the prey will learn to behave more humanely and safely.
The other day, one of my friends got hit, so I’ll be more careful.
On the other hand, for pitfall hunting, it seems that more systematic hunting was possible.
As shown in the figure, a group of humans could drive a group of prey animals into a herd and ambush them in a fixed position.
The production efficiency may have been enhanced by the fixed ambush of a group of prey animals as shown in the figure.
Also, clearly, the horizon has changed from a world of individual skill to a world of collective intelligence.
This may have promoted more strategic and systematic development of intelligence.
The social background of this change was not explained or disclosed.
It is a “trick technique,” if you will.
and controlling it in advance is also applied to interpersonal relationships.
It is easy to imagine that this kind of “ingenuity” to detect and control animal psychology was applied to interpersonal relationships as well.
It may have served as an opportunity to awaken to the intellectual pleasure of social manipulation and deception.

Well, it has been 37,000 years, so I am not sure how much we have improved our intelligence as a species, or how much our DNA has evolved.
I am not sure. However, it is about half of the time in the history of the present human species.
I would like to see how we have evolved during this period.
Although it is said that the first humans appeared in Africa about 70,000 to 80,000 years ago, the history of the present human species is still very different from that of the past.
In contrast to this, the accumulation of empirical knowledge in this archipelago is quite long.
The regional nature of the Japanese archipelago may also have played a significant role in the evolutionary process.
On the other hand, humans are thought to have shared their evolution over a fairly wide area through trade.
In fact, sharp and highly useful materials such as obsidian were distributed over a wide area.
I wonder whether such information sharing involved a specific “division of labor” function.
Did such entities as traders help to share wisdom in a specialized way?
The scale of my questions and interests keeps growing and growing, and I can’t stop (laughs). …
