About this site
Futo is a small fishing harbor on the Izu Peninsula in Shizuoka Prefecture, facing the Sagami Bay coastline of central Japan. It is a long established diving area for the Tokyo region, with dive operations running boat and shore access out of the harbor itself. The site is a reef reaching a maximum depth of around 40 metres, with the shallower sections rated as suitable for beginners. Squid are regularly seen here, and divers have also reported anthias on the reef.
