Shima

Shima is a coastal city in Mie Prefecture, Japan, on the Kii Peninsula facing the Pacific. It acts as a gateway to the Kumano region and offers access to coastal dive sites along the Pacific coast, including coral and rocky reefs, depending on local currents. There are several dive centers nearby (within reach of Shima) that provide boat dives, equipment rental, and courses. Conditions are typically warm for the region in summer, with clear to moderate visibility and a variety of small reef fish, depending on season and site. For inland or freshwater diving, options are limited; the city’s main draw for divers remains coastal access and proximity to renowned dive areas along the central and southern Japan coast.
