Takeda Nobutora built Sasao Castle when he was fighting with the local warlords for control of the Kai region. It is situated in the border area between Kai and Shinano to also help prevent assistance from the Suwa who were allied with the local lords of Kai. During the time of Takeda Shingen, troops were stationed here for the same reason. After the fall of the Takeda, there were a lot of skirmishes between the Hojo and Tokugawa in this area but there are no records of Sasao Castle playing a role.
A small castle ruin located on the cliff overlooking the river valley below. From the Nagano side it's downhill to get to the castle which is basically a flatland castle but the castle on the cliff is like a mountaintop castle from valley side. It reminds me of Nagurumi Castle in that sense. On the day I went, the first bailey, on the edge of the cliff, was closed off after heavy rains due to fallen trees and the danger of further erosion.
