Maguroana
About Maguroana
Maguroana is a distinctive rock formation off Yomejima in the Keita archipelago, featuring a half-submerged arch-like structure with holes in the rock. Large numbers of bluefin tuna gather around and inside these holes, sometimes forming very large congregations. Offshore, divers may also encounter large schools of fish, and dolphins are frequently seen and can be observed from the surface or during dives.
