里見氏
The original Kururi Castle was a mountain-top fortification built during the Muromachi period by Takeda Nobunaga (1401–1477), and was ruled by his descendants, the Mariya clan, from 1540. With the expansion of the Satomi clan from Awa Province in the Sengoku period, the castle was taken over by Satomi Yoshitaka, who used it as his base of operations against the Hōjō clan, based at Odawara Castle. The Hōjō attempted to take Kururi unsuccessfully on a few occasions, and finally seized it in 1564. They lost it just three years later in 1567, when the Satomi regained control.
