History

Positioned along a side ridge and connected to Ohtaniyama Fort, it may have functioned as a point of egress to the north—curiously away from the expected battlefield. It may have been intended as part of a retreat or resupply route, especially if the main route through Hayashitaniyama Fort was blocked or under attack.

See Battle of Shizugatake for more details.


Field Notes

From Tochidaniyama Fort, a side ridge leads to Kashiwadaniyama Fort, but there is no trail or signage—not even marked trees to guide the way. The route is fairly overgrown, and I found myself weaving back and forth, dodging thorny brushes and fallen trees as I followed the ridge.

At one point I nearly turned back, but trusted the terrain and eventually reached the ruins. The main bailey is clearly identifiable, as you’ll see in the photos, and the site is a worthwhile visit, if you’re prepared for a bit of off-trail adventuring.

From there, the ridge continues another 300+ meters to Ohtaniyama Fort (大谷山砦). I attempted to push forward, but the path was too choked with fallen bamboo and trees. After advancing only about 15 meters in tough conditions, I decided that climbing back through that mess going uphill wasn’t worth the risk or effort.

While most of the forts on the Mt. Gyōichi ridge are accessible via a clearly marked and maintained trail, Kashiwadaniyama and Ohtaniyama are best left to experienced hikers or those equipped with GPS and a good sense of direction.
