O-kuno Shima (34°17'N., 133°00'E.) lies N of Omi Shima, leaving a navigable width of 0.3 mile in the channel. A light is shown from the S end of the island; a beacon is shown from a drying rock at the SE end of the island. Lights are shown from several towers standing at the jetty heads of the port complex near Salzaki (34°20'N., 33°02'E.). The summit of the island is 108m high, and a large red and white pylon for overhead cables, near the summit, is very conspicuous. There are also conspicuous pylons on the N coast of Omi Shima, on the S coast of O-kuno Shima, and on the Honshu coast N of O-kuno Shima. An overhead cable, with a vertical clearance of 50m, spans the channel to the S of O-kuno Shima; another cable, with a vertical clearance of 41m, spans the channel to the N. The pylons supporting these cables are prominent.
