Is Mikurajima Wild Dolphin Swim happening right now?

As of today, peak season now, through ~August 31. Earth Exhibit tracks the live conditions and flags it the moment it is on.

Mikurajima, one of the Tokyo Islands, hosts resident pods of wild bottlenose/Indo-Pacific bottlenose dolphins that are regularly encountered by small-boat operators.

Licensed operators run guided swim-with-dolphin excursions during the calmer months when sea conditions permit, allowing responsible in-water encounters with wild animals.
