"Nagannu" in Okinawan means long - like the shape of this uninhabited island. As you can see from the picture, the lagoon surrounding this island is very large - making this a great location for banana boat rides, wakeboarding, parasailing, and other marine sports. During the summer months, many visitors get ferried out to Nagannu for fun in the sun.
As for the diving, once outside the lagoon this island drops off drastically to depth of 60 meters/190 feet. Mild currents are common, allowing for great drift diving. It is very common to see green sea turtles and large schools of blue fusillers swimming on the edge of the dropoff.
Check the map - the lagoon is massive for such a (comparatively) small island. Sorry, only Japanese descriptions. Depths in meters.
