Yato Castle

Yato Castle is a medieval fortress site located on a ridge near Mount Yatsugatake at around 850 meters elevation. The ruins sit protected by steep cliffs and rivers on multiple sides, and excavations have uncovered many objects from when people lived and worked here.

The fortress was built during the Heian period and belonged to Henmi Kiyomitsu, an ancestor of the Takeda clan who died here in 1199. The castle was eventually abandoned as power shifted in the mountain region.

The name Yato means 'night place' and reflects the castle's remote mountain setting in local understanding. Visitors can see displayed artifacts that reveal daily life here, including imported ceramics and religious items that people used centuries ago.

The castle site is best reached on foot, with most visitors taking around 45 to 60 minutes from nearby train stations. Wear sturdy shoes and bring water, as the walk covers hilly terrain with significant elevation gain.

The fortress features an unusual defensive layout with a large moat positioned inside the rampart rather than outside. This design choice sets it apart from typical castle fortifications of that era.
