Yonehara Reef
Boat-only Ishigaki coral shelf with a shallow reef and sandy drop-off.
Short guided boat runs reach a shallow coral top and sandy falloff, making it a relaxed reef-viewing stop when sea conditions stay settled.
About Yonehara Reef
Yonehara Reef is a boat-only coral site off Ishigaki's north side, built around a shallow reef top, hard coral heads, and a cleaner sandy falloff. It suits relaxed reef drifting, short boat-based outings, and careful snorkel or breath-hold sessions where the main reward is slow viewing over coral structure rather than deep water. Keep buoyancy tight and treat the reef edge as a delicate, weather-sensitive zone.
