Shimamawari (★3.9)
The top of the root is 6m and the bottom is 30m. The topography is like Ayers Rock in Australia sinking into the water. East, west, north and south are drop-offs. There is a small cave on the west side with a remote root. The current can be a bit swift, but it is not that strong. The tops of the roots are wide and covered with corals and anemones.
