Katsunuma clan residence ruins

The fortress stands on a river terrace at 418 meters altitude along the Hikawa River, featuring earthen walls and moats on its northern and eastern sides.

The residence belonged to the Katsunuma clan, who served the Takeda family until their downfall when they were accused of betraying Takeda Shingen.

Archaeological excavations revealed 23 building foundations, including numerous ceramic items from China and local regions, showing the high status of the inhabitants.

The site contains reconstructed gates, original stone foundations, and detailed information panels explaining the layout of workshops, living quarters, and water systems.

Researchers discovered evidence of gold refining activities through the presence of melting vessels with metal residues within the fortress grounds.
