About this site
Nagannu Minami (ナガンヌ南) is a boat-dive reef on the south side of Nagannu Island in the Chibishi islets, about 30 minutes from Naha, Okinawa, with a maximum depth of 18 m and an average around 10 m. The bottom slopes gently from 5 m down to around 25 m, with schools of fusiliers and purple anthias and leaf scorpionfish hiding in the scattered coral. The shallow flat areas are often used for introductory dives and courses; anemonefish, damselfish, parrotfish and scorpionfish are typical. Little current; suitable from beginner level.
