Otaru Aquarium: November closure and winter changes
The aquarium closes 24 November–11 December 2026 before its winter season. The marine-mammal park and amusement park are closed in winter, so summer itineraries do not apply unchanged.
Official information reviewedWhere should I start?
Regular 2026 operation ends 23 November; it is closed 24 November–11 December. Winter opening is listed from 12 December.
Planning this outing
Before combining it with the canal, check seasonal hours and decide whether the aquarium should come first. Confirm winter programmes on the day and leave time for the return bus.
Questions before you go
Can I visit in late November?

Which areas close in winter?
The marine-mammal park and amusement park are excluded from winter opening. Choose another season if those areas are your main goal.
What is winter last entry?
Winter hours are listed as 10:00–16:00, last entry 15:30. Arrive well before that cutoff rather than using it as your target arrival.
