Ogan - Ishigaki & Yaeyama
Ogan is an exposed pinnacle, often battered by strong currents, making it a dive for experienced hands only. We’ve seen large schools of dogtooth tuna and barracuda here, sometimes circling the main rock. The shallower depth means you get good bottom time, but you really need to be comfortable in surge and drift. It’s a site for those who enjoy the thrill of open ocean action.
