Built on a mountain at an altitude of 362 meters, it is the site of a medieval mountain castle and the best place to view Tsuwano. You can enjoy a panoramic view of the houses at the foot of the gentle mountain and Tsuwano River flowing through it. The sight of the stone walls of the castle ruins floating in the morning mist is like a castle in the sky. I also recommend the season of autumn leaves.
There are no structures now, but the stone walls are almost perfectly preserved.

On this day, we were only able to explore a small area of the summit. We were informed that wasps had built a large nest and that it was dangerous. It is wise to heed such warnings.
