Dolphin watching

An unforgettable experience encountering wild dolphins in the open ocean!
Children aged 3 and older are welcome to board.
Finless porpoises (family Phocoenidae) are dolphins that live close to land, and in Choshi, they can be seen throughout the year.

This is an exciting dolphin watching tour that sets sail off the coast of Choshi to search for the dynamic sight of wild dolphins. Located in a rich marine area where the Kuroshio and Oyashio currents meet, it is one of Japan's leading spots where you can encounter diverse marine life throughout the year. The thrill of spotting a pod of dolphins leaping out of the waves from the boat will surely become an unforgettable memory that will last a lifetime.
