Senma Coast （千間（センマ）海岸）

My favourites

The Senma Coast, on the east of Tokunoshima, is perfect for diving.
It is a vast area with numerous distinct features including caves and archways.
Highlights include coral reefs that are teeming with fish and other marine life year-round.
It is truly a top-class spot for watching fish. The area is also one of the best places to see sea turtles on the island.
Divers report roughly a 90% chance of seeing a sea turtle, and often spot several sea turtles on one dive.
