InaOhniwajou (1).JPG


Ôniwajō was the residence of the Ôniwa Clan. The Ôniwa Clan are thought to have been aligned with the Suwa Clan, and they resisted the hegemonic Ogasawara Clan during the Battle of Yokokawa. The history of this site is limited though the township of Miyanoshō-gō was long inhabited and Ôniwajō, probably a yakata (fortified manor hall) site, was its centre in the medieval era. Excavations were carried out during the construction of a new community hall on the site ('Katakuri no Sato').

Visit Notes

Ôniwajō site sits in a small satellite basin of the Ina Valley, located between the towns of Tatsuno and Ono (the latter settlement is administratively divided down the middle between the municipalities of Tatsuno (Kamiina District) and Shiojiri (formerly of Higashi-Chikuma district)). The nearby train station is called Shinano-Kawashima. I have often passed by here on my way to Ina so, after failing to get a good look from the train, I knew I had to just come here for myself to see if there was anything to see of the medieval fortifications. Regrettably there is not. The terrain would lend itself to easy defence in the east where there is a cliff, but the site is now fields.
