Freediving in Japan
Including Cape Zampa, Chichijima, and Isso Bay. On the map.
The vibe
Gliding down along vertical drop-offs or kelp forests feels intensely meditative, matching the quiet focus of coastal communities with deep maritime heritage. The warmer months provide comfortable breath-holds without heavy thermal gear slowing your descent. It remains a low-profile pursuit here, undertaken either independently or through quiet local dive outfits rather than loud resort scenes.
