Kagoshima City Aquarium — Kuroshio Tank

Kagoshima City Aquarium (いおワールドかごしま水族館) sits on the waterfront directly facing Sakurajima volcano, with the main Kuroshio Tank — a 1,500-ton tank housing whale sharks, manta rays, and tuna — visible from both inside the building and through exterior windows from the harbor promenade. The aquarium focuses on Kagoshima's marine ecosystems: the Kuroshio Current, coral reefs, deep-sea creatures, and local dolphins.

The dolphin pool is outdoor and open to the sky, with Sakurajima as backdrop during performances.
