About Chishi
Chishi is a boat‑only reef site on the north side of Zamami in the Kerama Islands, known for its narrow crevasse route. Divers pass through a reef fissure and enjoy the terrain-focused swim, which makes the site a favorite for those who like structure and coral scenery. It is commonly chosen in summer during southerly winds, when access is typically easier. Because the crevasse is one‑way, groups can stack up, so spacing and buoyancy control are important for a smooth pass.
