Nazumado

Nazumado is located on the western side of the island, directly facing Hachijo Kojima. This dive site features a unique setup with ropes that assist divers in entering and exiting a walled reef that descends steeply. Divers can observe a significant population of sea turtles, which are known to approach closely without fear. In the spring, a diverse range of nudibranchs can be spotted, varying in size from small to large. The site is also home to Juuzen, a butterfly fish species endemic to Hachijo Island and the Ogasawara Islands, which can be seen as juveniles. During the spring, these fish gather to spawn, along with the rare Juuzen Tama. Additionally, Lenten sea otters, from juveniles to adults, can be observed in this area.
