Select participants and date
You step off the stone parking lot at Maeda Misaki with the Atlantic-blue of the East China Sea opening to your left and the continental shelf dropping away like a hidden stage. Guides check masks and fins under a bright Okinawan sky; the ocean ahead hums and, when the swell eases, a slit in the reef promises an otherworldly glow—this is the Blue Cave.

Adventure Tips
Arrive early
Morning departures have calmer seas and fewer boats—plan to arrive 20–30 minutes before the start to complete forms and gear up.
Use reef-safe sunscreen
Chemical sunscreens harm corals; apply mineral-based, fully absorbed sunscreen before entering the water.
Secure small items
Phones, wallets, and loose jewelry should stay in your vehicle or locker—use a wrist strap for cameras.
Wear reef shoes to the shore
Rocky ground around the access points is sharp; lightweight reef shoes protect feet during entries and exits.
Local Insights
Wildlife
- Green sea turtle (hamaumi)
