The dive site is named “Kouri Zanpo,“ which translates to “broken lingering waves“ in Okinawan dialect. This name stems from the island’s history when it once existed but was targeted by naval gunfire during the postwar U.S. military occupation, resulting in its collapse. The main attraction of this dive site is a drop-off that descends to a depth of 40 meters. Divers typically anchor on the north side of two wash rocks, allowing them to explore the Babel tower-like coral formations at the end of the drop-off. Divers can follow a route that starts in shallow water, passes through the first arch, proceeds to the second arch, and returns to shallow water. There are numerous other fascinating sights to explore, and various diving routes are available. The curtain of light filtering through the arches is a particular highlight that shouldn’t be missed!

In the past, there was a substantial population of Yaemenid fishes, but unfortunately, over the last few years, around 80% of them have perished.
