These are the waters in the vicinity of Sadogashima Island and Cape Sawasaki-bana. Near Ogi in these waters is a famous diving spot with a high level of species diversity (Awata, personal communication). The vicinity of Cape Sawasaki is habitat for the rare species of Icelinus japonicus and jawfish. In addition, due to its unique terrain it is used as a spawning grounds by various species of coastal fish. For example, it is one of the few breeding areas for Alcichthys elongatus and Aptocyclus ventricosus (Awata, personal communication). In addition, the seaweed beds in the vicinity of Cape Sawasaki are in a highly natural state (Sakurai, personal communication).
