Kozagawa

Kozagawa is a coastal town in Wakayama Prefecture, Japan. While the area is known for its access to nearby dive sites along the North Pacific, diving locally is mostly accessed via day trips from larger coastal hubs rather than a large on-site dive scene. Expect a rocky coastline and temperate water; nearby sites typically feature reef-like formations with resident fish, occasional pelagics, and deeper walls accessible from boats. With a network of local centers a short drive away, Kozagawa serves as a gateway for divers visiting central Honshu who want to combine seaside scenery with multiple dive options in the region.
