The history of this site is obscure. The fort is thought to have been built by Kiso Yoshimasa in the Sengoku Period. Given its small scale, it was likely only used as a look-out position.
There is a semi-circular stone wall half way up the ridge here known as Sakurasawa-toride. "Toride" refers to a small fort. I was quite confused because the bailey is only very small, and there is no protection to the rear. I climbed further up the ridge but there's no obvious ruins up here, although it does flatten out somewhat before sweeping further up. The wall, or parapet, seems partially formed through piling, but also partially cut into bare rock. There is some terracing toward the bottom of the ridge, but this may not be related to the fort. The site is very mysterious. Due to its small scale, the fort was likely only an observation post.
