Hadanashijou (4).JPG


Hadanashijō was constructed in 1305 by the Ao Clan who were granted a fief in the area by the Ashikaga Shogunate. In 1556 the Okudaira Clan, vassals of the Oda Clan, attacked Hadanashijō but were repelled. Ao Naganobu was the castellan at that time.

In 1560, following the battle of Okehazama, the Matsudaira Clan became hegemonic in Mikawa, and Ao Naganobu, who was not friendly to them, was forced to retire, being replaced by his heir, Ao Nobumori.

During the Mikawa Ikkō-Ikki rebellion of 1563-1564, Ao Nobumori relocated to Mutsunajō, and the Sakai Clan took over Hadanashijō. The castle is thought to have been abandoned not long after.

Visit Notes

Hadanashijō is an elevated kyokan (residential castle) ruin in Hadanashi Township, Okazaki Municipality. The ruins consist of a flattened ridge terminus with a long, 5m wide, 3m deep horikiri (trench) and dorui (berm) system on the ridge above. There is a narrow terraced band between the dorui and bailey space. There is a signboard and monument for the castle in the former bailey.
