Kanagawa is an administrative region on the eastern coast of Honshu, Japan, facing the North Pacific. Diving here combines convenient access from major urban centers with offshore and coastal sites in the Philippine Sea and nearby coastal waters. Typical diving features include rocky coastlines, man-made harbor zones, and sheltered bays hosting a variety of small reef-associated species, sea grasses, and occasional pelagic activity in deeper channels. Popular cluster areas are along the Miura Peninsula, with dive centers operating from coastal towns and cities such as Miura, Zushi, and Fujisawa, plus nearby shore-based access from Yokohama. Inland freshwater bodies like Lake Hinuma offer different diving options nearby for freshwater enthusiasts. The region offers good year-round access for shore and boat dives, with water temps ranging seasonally and visibility variable by site. Suitable for recreational divers looking for easy access trips and weekend dives from the Tokyo area.
