The Emerald Green Sea

There is a path from the public restroom next to the parking lot that leads down to the old Oyashirazu Tunnel, which is about 300 meters away. From there, you can take a path down to the beach, and as you descend a little, the view suddenly opens up. The clear emerald green sea is refreshing to the soul. Although the descent is steep and has a significant drop, it is worth the effort.
