Funka Bay's

They migrate in large groups, traversing between northern and southern waters during the transitions between summer and winter. They arrive in Funka Bay in spring and stay until autumn, feeding and raising their young.
This bay serves as the Pacific White-sided Dolphins' breeding and parenting ground, with mothers and calves visible from June onwards.

Dolphins start appearing off the coast of Muroran around mid-May, and sightings dwindle by September. Star Marine operates tours only when the chance of encountering dolphins is high, from June to August.

They really swim in groups!
I can't believe you can see dolphins in Hokkaido!
I was afraid we wouldn't see any, so I'm so glad we got to see them.
I never imagined we'd see so many of them!
They swim so fast!
