The warm, clear seas around Kagoshima’s southern islands — especially Yakushima, Amami Oshima and the Amami archipelago — make the prefecture one of Japan’s finest destinations for diving and snorkelling. Bathed by the warm Kuroshio current, these waters teem with life: vibrant coral reefs, schools of tropical fish, sea turtles, rays and, in places, larger marine life, all in visibility that can be superb. Around Yakushima, divers explore reefs and granite underwater landscapes and often encounter sea turtles, while Amami’s extensive coral reefs and lagoons are a highlight of southern Japanese diving. Dive shops on the islands cater to all levels, offering guided fun dives for the certified, introductory dives and courses for beginners, and easy snorkelling trips for families. Warm-water diving, abundant coral and the chance to swim with turtles make Kagoshima’s islands a rewarding underwater destination.
