Kawahira Bay, Ishigaki Island's No. 1 scenic spot, about 30 minutes by car from Ishigaki Island Town. There is a sandy beach and an observatory, so it is recommended to take a short walk before taking a glass-boat. There are several glass-boat companies, and there are many ports to leave, so you can rest assured without making a reservation. Recommended with a lot of very beautiful corals and fish.
