Why we send people here

The water really is that colour — shallow, white-sand-floored and lit from below. You cannot swim: the current is serious and black pearls are farmed in the shallows. Glass-bottom boats are the intended way to see it, and they are worth the fare.

Why it earns the hours
  • Our number 2 for Ishigaki, out of ten. It is the first thing we would spend the hours on.
  • Free; boat ~¥1,300 to visit.
  • On a 4–6h ashore call our verdict is "As the one thing" — out, boat, viewpoint, back, and lunch in town after.
Before you count on it
  • Always; boats ~9:00–17:00.
  • No single published ride covers this one. Budget for a taxi both ways, or fold it into a guided day.

The story

Why Kabira Bay is famous

Kabira is the postcard of the Yaeyama islands, and it is the rare famous bay you are not allowed to swim in: the current is strong and the water is a working black-pearl farm. Glass-bottom boats exist for exactly that reason. Michelin's Japan green guide gives it three stars.

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.

Before you go

Things worth knowing

  • Fix your return before you get out of the car. There is no taxi rank at Kabira.
  • The glass-bottom boat is the point. Standing on the viewpoint and leaving is half a visit.
  • Light is best from late morning to early afternoon, when the sun is high enough to reach the sand.
  • For actual swimming, Sukuji and Yonehara beaches are nearby and permitted.
Where it is

Kabira Bay and your ship

Both pins on one map, so the distance is a fact rather than a feeling.

The arithmetic

Where the 3 hr goes

Counted from the moment you step off the gangway. The hour before all-aboard is not in this bar; it is already set aside.

Out35 minCar ~35 min
There1 hr 50 minWhat you came for
Back35 minTo the gangway

35 minutes each way is the honest figure for car ~35 min, not the optimistic one. If your ship is late, cut the 1 hr 50 min in the middle. Never cut the hour at the end.

If you have longer

What fits alongside it

Each of these still lands you back aboard with the hour to spare on a 6-hour stop ashore.

Asked about Kabira Bay

Questions people send us

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.
