Explore coral gardens on a glass-bottom boat

The emerald sea against a blue sky, fine white sands and shoreline forests all make Kabira Bay one of the greatest spots for natural beauty on Ishigaki Island .

There's an observation spot that provides a breathtaking view of the bay and its nine uninhabited islands. There is plenty to see at ground level too. But the best way to see the bay up-close is on one of the bay's glass-bottomed boats.

The world's first black pearl was cultivated in Kabira Bay

How to Get There

There is a bus from New Ishigaki Airport to Kabira Bay, but it only leaves twice a day, at noon and 3:00 p.m. It takes about 40 minutes. Car rental is the best way to get around the island. Kabira Bay is a 30-minute drive from Ishigaki City and a ticket for a glass-bottom boat trip includes free parking.

Explore the coral gardens

The emerald sea and white sand may be enticing, but swimming is not allowed because of the black pearl cultivation in Kabira Bay. It is one of only two places in Japan that cultivates black pearls (the other being the neighboring Iriomote Island). You can buy a ticket for the glass-bottomed boat tour from one of the shops near the car park. Boats leave every 15 minutes and there's no need to reserve ahead of time. The guides will lead you to the best spots to see turtles, clams and clownfish so close you feel you can touch them.

Other ways to explore the bay

Climb to the top of the hill to the observation spot for a magnificent view of the bay and its nine uninhabited islands. You can buy tickets at the marine stores for tours to take you around the islands. It takes about three hours. Near the observation tower is a small temple also well worth a visit. It was built in the 17th century when Kabira Bay was an important port.
