★★★★☆ Manta Ray Scramble
This dive site, located on the northwest side of Ishigaki Island, has one of the highest rates of encounters with manta rays in the world. It can be reached by boat in 10 to 15 minutes. The water depth is around 10-20m and the tide is relatively calm but can become stronger at times. A small hill in the middle of the sea is a cleaning station where the manta rays come to visit. Manta rays swim around at a depth of 5 to 10 meters, so you can see them by snorkeling.
★★★★☆ Crystal Beach
Crystal Beach (Yamahara Beach) in Kabira, Ishigaki, is a secluded site with natural crystal deposits from Mt. Omotodake’s river. Its unspoiled waters host coral reefs, tropical fish, and sea turtles. Access is via a steep slope with limited facilities, so preparation and caution are essential.
★★★★☆ Yonehara Reef
Yonehara Reef is found at the point in Kawadaira, in the northern part of Ishigaki Island. This site is a boat entry only. The average depth is 5 to 30 meters. There is a coral shelf at 5 to 6 meters deep that drops into a sandy area in 20 to 25 meters of water with three roots, densely populated with table and eddy corals.
★★★★☆ Sakieda Maze
Sakieda Maze in Kabira, Ishigaki, features complex reefs with arches and tunnels lit by sunlight, creating magical views. With depths of 3–15m and little current, it’s beginner-friendly. Shallow coral reefs teem with marine life, including clownfish and spiny dogfish.
★★★★☆ Yonaguni Monument
The Underwater Ruins were discovered by a local diver in 1986 and is a popular diving spot in Yonaguni along with hammerhead sharks. It’s about 15 minutes from the port. A huge staircase-shaped wall spans about 250m east-west and 150m north-south to form the ruins.
★★★★☆ Hammerhead Rock
The westernmost island in Japan. It’s closer to Taiwan than Ishigaki Island. It takes about 45 minutes from Ishigaki Island to reach by plane. The highlight of this island is the high chance of seeing hammerhead sharks. Among them, this is the point where the rocks, like buildings, stand vertically from the bottom of the sea at a depth of 35 meters.
