About dolphin swimming

Dolphin swimming season is mid April to October.

The type of dolphins you see around Mikurajima are Indo-Pacific Bottlenose Dolphin.

Almost all dolphins are solidly identified by the research team and have names

The number of dolphins confirmed last year/2018 was about 150.

10-15 babies are born every year.

Basically they are very friendly.

They sometimes come very close to us but sometimes just pass by because they are wild.


A dolphin swimming tour is for two hours.
When you find dolphins, you enter the sea and return to the boat when they are gone.

You can swim with them by snorkeling and free diving. Scuba diving is prohibited in Mikurajima.

Please follow your guide’s instructions.
