Wandering through the 400-year-old ancestral lands of \u201cIri no\u201d in Kawachi, Higashihiroshima City…
\nGuided by a Hiroshima Prefecture regional historian who rigorously scrutinized the materials, and focusing on local \u201cinsights\u201d and observations. The precision of this flesh-and-blood chronological exploration gradually deepens…<\/p>\n

Lately, I’ve been preoccupied with the full-scale snow removal emergency mode triggered by the heavy snowfall (lol), but I’ve been steadily progressing with the in-depth research for the \u201cFour Hundred Years of Life’s Resume\u201d series. This is a different dimension of historical inquiry compared to the nationwide narratives of Nobunaga, Hideyoshi, and Ieyasu\u2014a new frontier, so to speak, of \u201ccommoners’ history\u201d where you can feel the flesh and blood.
\n\u3000Since my last blog post (January 6th: [Homestead: Irino \u2013 Ancestors Return After 210 Years, Descendants After 420 Years]), I’ve continued reviewing various documents about the ancestral homestead. Among these, I have carefully referenced information from Mr. Kosuke Nishimukai, a renowned researcher of Sanyo regional history (then employed as a researcher at the Hiroshima Prefectural Archives), as well as field investigation and oral history information from Mr. Sadayoshi Chika of the Kawachi Town Board of Education, which includes my ancestral home, Irino. ~ Significant findings from my second brother’s research. ~
\n\u3000As a member of my generation, I have been conducting genealogical research based on records written by my sixth-generation ancestor (referred to as the sixth-generation progenitor) who visited our ancestral home, Irino, and documented the deeds of his grandfather, three generations prior, who served as a \u201cSokumyaku\u201d (administrative official) for the Hiroshima Asano Domain.
\n\u3000What has recently struck me as I’ve pursued this research is the persistent presence of \u201ckakuchi\u201d (enclosed plots) in this area. Stone walls resembling castle ramparts exist at the base of locations passed down as family burial grounds, and an old Edo-period place name, \u201cKita-no-Kakuchi,\u201d remains preserved.
\nThe photo above shows the stone wall at that base. The photo below is Wakayama Castle in Kishu, which I visited several years ago. It shows the \u201cTakaishigaki\u201d (High Stone Wall), attributed to the warlord Todo Takatora, renowned for his castle-building skills from the Sengoku period to the early Edo period. I have absolutely no knowledge of civil engineering. However, even to my untrained eye, the very bottom section of the top photo, which shows a modern \u201cstone wall,\u201d appears to have a different construction style from the stone wall, and I can’t help but feel a similarity to the \u201cTakaishigaki.\u201d<\/p>\n

\u3000This photo is from Google Maps. You can clearly see the embankments firmly constructed along the tributary of the Irino River flowing from the mountainous area in the far right background through the ancestral lands of Irino. The family lineage known as \u201cKakiji,\u201d who settled here from Kishu on slightly elevated ground, possessed a certain level of technical skill and knowledge in river and civil engineering management. It is conceivable that the Asano clan, transferred to Hiroshima as part of a domain transfer, strategically placed this lineage in this key location, anticipating potential flood damage. This also aligns with the salt field civil engineering techniques that would become relevant in later periods.
\n\u3000This led me to infer that my family lineage was placed here as \u201cadministrators\u201d precisely because of the importance placed on governing and managing Irino\u2014a region that functioned as a political, economic, and military hub. It was a vital point where the ancient Sanyo Road, the most important official route connecting Dazaifu and the capital, passed through, established under the Heian period’s Ritsuryo system. It was a place of active logistics and human traffic.<\/p>\n
