Tobi Shima (39°12'N., 139°33'E.), a relatively flat topped island, lies about 15 miles WNW of Mi Saki. There are three hills of almost equal height; the S hill is 71m high to the tops of the trees and Tobi Shima Light is shown from the N hill. The shore of the island consists of beaches of sand and shingle, fringed by drying rocks. The island is surrounded by rocky shoals, except off its SE side. Oshaku Shima, 76m high, is the N and largest of a group of rocks and islets about 1 mile W of the S extremity of Tobi Shima. The group is almost joined to Tobi Shima by rocky shoals.
