Years: 1442 - 1442

Yamana Norikiyo, the shugo daimyo of Mimasaka Province in western Honshu, had in 1441 ordered his relatives to build a castle in Tsuru mountain in Tsuyama Domain, which lies along the upper Yoshii River, in the center of the Tsuyama basin to build a castle.

However, the castle will be abandoned when the Yamana clan declines after the Onin War.
