The aquarium of Kinko Bay, the deep bay the volcano sits in: a large Kuroshio-current tank, the waters of the Nansei Islands, and the local depths off Kagoshima. 9:30–18:00, last entry 17:00; adults ¥2,000, children ¥1,000. Closed for four days from the first Monday of December (7–10 December 2026 by that rule) and on 15 and 22 December 2026. The easiest indoor stop for a ship at Kita-futo, and the rain plan.
- On a 4–6h ashore call our verdict is "Perfect" — Aquarium plus the ferry terminal next door; add Tenmonkan by tram.
- 9:30–18:00, last entry 17:00 — open until 21:00 in Golden Week, on summer-holiday weekends and at Obon. Closed four days from the first Monday of December (7–10 Dec 2026 by that rule), plus temporary closures on Tue 15 and Tue 22 December 2026..
- 3 hr 30 min door to door needs a 5.5-hour call: a 2–3 hour stop cannot hold it. Pick something closer instead.
- No single published ride covers this one. Budget for a taxi both ways, or fold it into a guided day.
Things worth knowing
- Coin lockers are ¥100 and refunded after use; leave your bag and jacket.
- Show and feeding times are on an event image on the English page; the aquarium's phone line is +81 99 226 2233.
- The Sakurajima ferry terminal is about 5 minutes on foot from the Kita-futo berth; the ferry costs ¥250, paid on the Sakurajima side.
- The City View bus stop is named 'Kagoshima Aquarium (Sakurajima Pier)'. Day pass ¥700, covering trams and city buses.
Kagoshima Aquarium (io World) and your ship
Both pins on one map, so the distance is a fact rather than a feeling.
Where the 3 hr 30 min goes
The hour before all-aboard is not in this bar; it is already set aside.
If your ship is late, cut the 3 hr 15 min in the middle. Never cut the hour at the end.
Questions people send us
How much is Kagoshima Aquarium?
¥2,000 for adults and ¥1,000 for elementary and junior high school children. The English page lists no senior discount.
How do I get there from the cruise port?
From Kita-futo it is next to the route to the ferry. From Marine Port, take the ship shuttle to Tenmonkan, then a tram to Suizokukan-guchi (¥200) and walk about 8 minutes.
Is the aquarium open on 7 December?
No. It closes for four days from the first Monday of December, which is 7 December in 2026; the aquarium does not list the exact dates, so confirm if you call then. It also has temporary closures on Tue 15 and Tue 22 December 2026.
