About Ogi Port
Ogi Port on southern Sado is a terrain-forward dive area with drop-offs, reef sections, and a marked Happy Jizo point that gives the site a clear local reference. It suits divers who want structure, marine life, and a site that changes with water movement rather than a shallow sightseeing reef. Plan on local support from the Kotoura side, conservative timing, and solid buoyancy control.
