Nishiachiwa Castle (Mikawa)

History

Nishiachiwajō was constructed around 1421 by Matsudaira Nobusue, the younger brother of Matsudaira Nobumitsu, the third sōke of the Matsudaira family. Nishiachiwajō was a satellite fortification of Iwaźujō (Iwazu Castle). Nobusue, whose small fief was worth about 35 kan (350 koku?), was succeeded by such lords as Nobuchika and Nobutoyo. It is said that Nishiachiwajō was destroyed by fire in the late Sengoku period. The castle site has been occupied by a temple since the Shōwa period.

Visit Notes

At the site of Nishiachiwajō in the small township of Nishiachiwa, Okazaki Municipality, nothing remains definitively of castle ruins, but the hill sits above surrounding rice paddies and waterways looking very defensible. To the rear of the site I found some terracing in a bamboo grove, but nothing that couldn’t’ve been carved in later times. Modification of the terrain is ongoing today, and many diggers beneath the temple which now is hosted by the castle site could be seen chipping away at the hillside. It seems a new terrace is being carved out. This had the bonus of showing the hillside quite clearly, so that the castle site was instantly recognisable, but it means that the terrain has been altered further from the time of the castle.
