The castle supported the Saitō, Oda and Toyotomi clans.

Though Sadayasu supported the Toki clan, Katō Mitsuyasu, his father, supported the Saitō clan and Toyotomi Hideyoshi, who provided many of the stones for the construction of the castle.

Mitsuyasu join in the invasions of Korea, but died of illness during his trip home in 1593, putting Sadayasu in charge of construction.

At present, there is a marker designating the former location of the castle.

Though the donjon no longer exists, the moat, earthen walls and foundation stones still remain.
