Dive-site story
Located on the Osezaki peninsula projecting into Suruga Bay, this site serves as a cornerstone of mainland Japanese scuba diving. A hooked gravel spit creates a sheltered inner bay that remains calm even during stormy weather, transitioning from shallow gravel flats into a steep silty slope. Divers explore underwater shrines, artificial reefs, and deep muck zones celebrated for bizarre macro critters and pelagic visitors wandering in from Japan's deepest oceanic trench.

World-class macro habitat famous among underwater photographers for rare critters and deep-water visitors
Sheltered inner bay offering calm conditions when nearby open ocean sites are blown out

Seasonality
Autumn brings warm water and peak macro diversity, while winter offers the clearest water and opportunities to find deep-sea migrants ascending from the abyss.
