A strange rock on Yomejima, the southernmost island in the Keita archipelago, about 50 km from Chichijima. The Arc de Triomphe is half-submerged in water. Bluefin tuna congregate in the holes, sometimes as many as 100 or more.
In addition to bluefin tuna, bluefin crocodiles can often be seen. If you go offshore, you can see large schools of fish such as the blue-and-white crested woodpecker and the black-headed coral reefer. There is also a high rate of encounters with hand dolphins, which can be observed from the surface of the water or even during a dives.
