Conditions or access may require a local guide. Dive with a local operator.
Sakuraguchi is a sheltered southern Ishigaki reef site with shallow coral gardens, a sandy bottom, and a small cave-like feature on the reef top. It is a beginner-friendly boat dive when north winds are strong, with hard and soft corals, lively fish, and a photogenic mix of reef and sand. Clearer high-tide windows make the site feel especially relaxed.
