The coast of Shikoku, from Mi Saki (34°15'N., 133°34'E.) to O jima(34°00'N., 133°22'E.), about 18 miles SW, forms a large bay with generally level sandy shores and a few steep places. Anchorage can be taken in suitable depths, about 1 mile off the coast, except in the vicinity of Mi Saki, in a bottom of mud, or mud and sand. The tidal currents are weak and there are few uneven parts in the seabed, but there are many fishing nets and seaweed cultivation grounds along the coast, some of which extend up to about 1 mile offshore.
