Ehime

Ehime is an administrative prefecture on Shikoku Island, with a coastline facing the Seto Inland Sea and Pacific Ocean. The region offers a mix of coastal dive access from ports around Matsuyama and Uwajima, plus limited offshore options along the coast. Due to relatively shallow waters and varied habitats, diving here tends to focus on macro life, rocky shores, and local bays rather than world-class offshore reefs. Nearby Minamiuwa District provides access to more rugged coastal scenery; Ainan can serve as a polite entry point for local dives. Overall, Ehime provides modest, accessible diving for recreational divers staying in western Shikoku, with emphasis on practicality and local marine life.
