Katsurahama Aquarium is a small, old-fashioned aquarium by the Katsurahama coast. The tanks and pools cover fish, water birds, seals, and dolphins, with scheduled animal shows adding a family-friendly reason to linger.
It works best as part of a Katsurahama outing rather than as a standalone trip across Kōchi. Visit for an easy break between the beach, the headland views, and nearby temples.
