Frequently Asked Questions
It's built around the Seto Inland Sea itself — tanks recreate the local straits and whirlpools, and the dolphin pool sits against an open horizon so the animals appear to swim in the sea. Around sunset it's one of the most photogenic aquarium views in Japan.
It's a short walk from JR Utazu Station, about 20 minutes from Takamatsu — easy to slot into a Kagawa day between udon stops, or on the way to or from Okayama across the Great Seto Bridge.
It's a compact, well-curated aquarium — one and a half to two hours covers it comfortably. If you can, time your visit so you end at the dolphin pool near sunset, when the Seto Inland Sea turns gold behind it.
