About this spot

Amaushiji, located at Fukashirono Saki cape in Okinawa Prefecture, delivers consistent diving conditions throughout the year. The site sits outside marine protected areas, making access straightforward for visiting divers. Local observations document 12 distinct species, indicating a healthy ecosystem with good biodiversity for a day dive. Coral health at Amaushiji shows no stress indicators, a significant advantage in Japan's warming waters. This means the reef structure remains intact and vibrant, supporting the species that make the site worth visiting. The cape's geography creates natural shelter and current patterns that attract reef fish and larger pelagics depending on season. While specific depth and visibility data aren't widely published, the site's year-round status suggests reliable conditions without extreme seasonal swings. Community video content exists, giving divers a preview of what to expect. The modest species count should not deter you—quality beats quantity at many Japanese sites, and Amaushiji's lack of bleaching stress means what you see will be thriving.
