Why it's worth your hours

Shallow water over white coral sand, with granite islets scattered across it. The colour is not a filter — it is what happens when sunlight passes through two metres of clear water and comes back off white sand.

You cannot swim. The tidal current through the bay is genuinely dangerous, and black pearls are cultivated in the shallows. The glass-bottom boats are the intended way to see it, they run every fifteen minutes or so, and they are worth the fare.

Quick answers

FAQ

Why can’t you swim at Kabira Bay?

The tidal current through the bay is strong enough to be dangerous, and black pearls are cultivated in the shallows. Glass-bottom boats run instead and are the intended way to see the water. For swimming, Sukuji and Yonehara beaches on the same coast are permitted and close.

How do I get to Kabira Bay from the cruise berth?

By taxi or tour, about thirty-five minutes each way — there is no practical bus for a port-day schedule. Fix your return before you get out of the car, because there is no taxi rank at the bay. Budget about three hours door to door.

Whatever the plan: back aboard 60 minutes before all-aboard. Full port context on the Ishigaki guide.
