Said to have been built by the Kurashina clan, the actual date of construction and history are mostly unknown. The Kurashina may have been an offshoot of the Murakami, but little is known of them. When the Murakami fled Takeda Shingen in 1553, it is said that the Kurashina fled to Azumino (near Matsumoto) while the Murakami fled to Echigo (Niigata). The role of Washio Castle is unknown after this point but it was likely used by Takeda Shingen to fortify the entranceway to the large Zenkoji Plain. The Seino clan who originally fled with the Murakami to Echigo returned in 1559 and joined with the Takeda. It is thought they were given control of Washio Castle sometime around 1570. The castle was likely abandoned in 1598 when Uesugi kagekatsu moved to Aizu and the Seino joined them.
Sanada Nobuyuki's second daughter had a residence at the foot of this mountain too. Today there is a small garden and shrine where it once stood. A bit farther up the mountain was also a small temple that destroyed in a rainstorm in 1742. Given the steepness of the slope, I'm not surprised.
