This dive site, known as "Kouri Zanpo" (broken lingering waves), has a unique history stemming from an island that collapsed due to naval gunfire during the postwar U.S. military occupation. The main attraction is a dramatic drop-off descending to 40 meters, though recreational dives typically stay within 24 meters. Divers usually anchor on the north side of two wash rocks to explore the Babel tower-like coral formations and follow a route through two fascinating arches, starting in shallow water and returning to it.
Lucky divers may encounter Napoleon wrasse, Nemuribuka (sharks), Stingrays, and Sea turtles. Commonly seen species include Smilax longfin snappers, gobies, wrasse, and butterflyfish. Seasonal rarities like Cinderella nudibranchs and shrimp add to the macro photography opportunities.
The highlight for many divers is the spectacular curtain of light that filters through the arches, creating a magical underwater ambiance. With various diving routes available and shallow areas accessible, the site is suitable for different experience levels, including freedivers and snorkelers. While no specific best time to visit is mentioned for big animals, the arches and coral formations are a year-round draw.
