Builtin: 1590 by Toyotomi Hideyoshi
This castle was built for only attacking Hojo clan and Odawara Castle. However, Hideyoshi, built this castle with lots of Ishigaki, the stone walls, Tenshu, the huge well for long term battle. Mt. Ishigaki was the first castle which used Ishigaki in Kanto Area. Hideyosh spend 80 days with 40,000 men to built this castle and set his headquarter. His strategy of the attacking Odawara Castle was completely surrounded and lead the internal collapse of Hojo and his soldiers. This interesting approach of Mt. Ishigaki Castle deadened the motivation of Hojo's
Hideyoshi stayed about 100 days in this castle. He brought one of his wife Yodo, and let all other samurai bring their wife at this battle field, too.
The Stone walls were Nozurazumi Style built by Anou People. They still remain in great condition even under the several times of huge earthquakes.
