Iwaoka Yakata

History

Iwaoka-yakata is thought to have been the fortified manor house of the Iwaoka Clan, a branch family of the Inukai Clan. The Iwaoka fought for the Ogasawara during the Takeda Clan invasion of the province, and at that time Iwaoka Ishimi was killed in battle. The Iwaoka would go on to fight for the Ogasawara again during their siege of Hikijō in 1582.

Visit Notes

The ruins of Iwaoka-yakata were the first stop on my impromptu "Yakata Tour" that day. Cycling, I managed to visit thirteen former yakata sites on the Azumi Plain. Not bad for leaving the house at 10:30am. Iwaoka-yakata was the first stop, located just north of the Azusa River. I was able to locate a signboard for the medieval yakata, but there were no obvious ruins. The signboard shows pictures of relics, mostly ceramics, unearthed during the construction of what I think is a small water treatment station in the Late Heisei Period. There is little information about the history of the site but the sign says that the building remains unearthed were likley a storehouse.
