The warm seas off Yakushima and southern Kagoshima are a rewarding spot for whale and dolphin watching. From roughly January to April, humpback whales migrate through these waters, and boat tours head out for the thrilling chance to see these giant creatures breaching, spouting and diving in the open sea — an unforgettable wildlife spectacle. Pods of dolphins are also frequently encountered year-round, often riding the bow waves of the boats and delighting passengers with their acrobatics. Tours are run by local operators from Yakushima and other ports, with experienced crews who know where to find the animals. Sightings are never guaranteed with wild animals, and trips depend on sea conditions, but the excitement of spotting a whale or swimming dolphins in Kagoshima’s beautiful southern seas makes a boat tour a memorable addition to an island visit, especially in the winter–spring whale season.
