Being a former fort site, it's a place with excellent views. From the fork between the shrine route—where Princess Matsu's mountain-crossing staff is placed—and the Onnazaka route, it's 15 minutes via the shrine, and going down the Onnazaka route to Shingen-in takes under 15 minutes as well. This route has spots with better views. Also, from here you can reach Dairokuten in under 10 minutes, so I also recommend enjoying the panorama from its summit, which has even more open views. The path isn't steep and is easy to walk.

A fort that guarded the east side of Hachioji Castle; a hiking course continues from a temple called Shingen-in. From here you can also head toward Hachioji Castle. It's a place with a great view, ideal for watching enemy movements. No particular remains are left, but you can tell it was a small fort meant for surveillance.
