Ago Wan (34°17'N., 136°47'E.) is entered between Goza Saki and Meto Saki about 1.5 miles N. The bay is open W and penetrates deeply to the E; there are many branches and islets in the bay. Although the bay is protected against winds it has several dangerous rocky, oyster beds, and fixed fishing nets, all of which narrow the traffic routes and make it suitable only for small vessels with local knowledge.
