Excavations point to a refuge castlethat became a lord's castle.

Ishigami Castle Site stands at the edge of a plateau where the Kuji River once meandered widely. The village records that it began as a refuge castle where local people sheltered temporarily, and that late in the Sengoku period its moats and earthworks were reworked into a lord's castle. To the south is Chosho-in, the family temple of the castle's lords.
