Adventure with us among the remarkable topography that boasts largest coral reef area nationwide, stunning tropical fish, and marvellous shaped geological forms. The sea around Tatsukushi and Minokoshi is a natural wonderland waiting for you to discover.
The sea around Tatsukushi, home to plate coral, is Japan’s first undersea marine park to be designated as such in 1970.

While gazing into the undersea world, you can see various marine creatures, including table and plate corals, and colorful fish through the glass-bottomed boat.
One particularly fun part of the glass-bottomed boat tour is coming ashore at Minokoshi Beach.

The beach, covered with millions of naturally weathered honeycomb rocks, is a piece of art in itself. Take time to walk around this incredible landscape and natural scenery.

(Each round-trip glass-bottomed boat ride lasts about half an hour. Duration of sightseeing 60 to 100 minutes, including a stroll on Minokoshi Beach)
