From Mt. Daikan, the highest peak on the south side of Mt. Hakone’s old outer rim of the crater, the castle ruins can be seen on the upheaved part of the ridge that slopes down in the direction of Yugawara on Sagami Bay. They are said to be Sanehira Doi’s castle remains, but historical investigation has yet to make a decisive conclusion. At the foot of the mountain along Sagami Bay, however, there is so called Atami Road which connects Odawara with Izusan, Atami and Nirayama. As can be guessed from the fact that Yoritomo Minamoto raised an army in Ishibashiyama, the road seems to have been an important traffic route, in an important position, since old times, and it seems that these castle ruins had something to do with Sanehira’s connection to raising an army.
