Ibaraki’s prefectural aquarium, on the sea at Oarai, with ocean sunfish among its big tanks. 09:00–17:00, last entry 16:00; winter 09:00–16:00. No weekly closing day; maintenance closures in June and December (7–11 December in 2026). Adult ¥2,300, primary and junior high ¥1,100. Indoors: the rain pick.
- 2 hr 30 min door to door needs a 4.5-hour call: a 2–3 hour stop cannot hold it. Pick something closer instead.
Aquaworld Oarai and your ship
Both pins on one map, so the distance is a fact rather than a feeling.
Where the 2 hr 30 min goes
The hour before all-aboard is not in this bar; it is already set aside. The minutes are our estimates from timetables and maps, not timed on the ground.
If your ship is late, cut the 1 hr 50 min in the middle. Never cut the hour at the end.
Routes that already include it
Finished days timed from official timetables and our estimates, with this stop in them.
What to put beside it
Each of these still lands you back aboard with the hour to spare.
