Seiyo

Seiyo in Ehime Prefecture sits on Shikoku's western coast facing the North Pacific. It’s not a major diving hub, and the local diving footprint is limited. The nearby waters are part of the Philippine Sea, with coastal conditions typical of the region. For divers, access typically centers on day trips from larger prefectural towns or nearby marine centers, rather than a city-based dive scene. If you’re exploring this area, expect modest reef- and coastal-ecosystem encounters and the chance to coordinate with nearby operators for access to local dive sites and training options in the broader region of Shikoku and Ehime.
