龜山城

Kameyana Castle sits on a forested hill in the Nagato region, with a shape that resembles a turtle from above. The remaining stone walls are built into the terrain, with the western section standing higher than the eastern side.

The fortress was built in 1446 by Washizu Hirotada during the Muromachi period as a defensive structure against anticipated threats. It served as an outpost controlling the coastal region from potential invaders approaching by water.

The castle grounds preserve ancient military engineering techniques through remaining stone walls that showcase traditional Japanese fortification methods.

Access is reached via a walking path between Horenji Temple and the Nagato Environmental Health Center, which passes through a cemetery. It is advisable to wear sturdy footwear, as the path can be steep and uneven in places.

The fortress was directly connected to Fukawa Castle and helped protect coastal areas from sea-based attacks. Its strategic location enabled coordinated defense across multiple strongholds in the region.
