When planning a family trip from Sapporo to Otaru that includes Otaru Aquarium (), first check whether your travel date falls within that year’s opening schedule, then decide how to divide your time between the aquarium and the city. Using the aquarium’s official ticket page (checked 2026-10-28), this article sets out its regular 2026 opening season and admission prices for different ages, with tables to help check half-day and full-day plans. For other places, see the Otaru travel guide and Hokkaido travel overview.

Key points

  • The aquarium’s officially listed regular 2026 opening season runs from 14 March to 23 November. These dates cannot simply be used as the 2027 calendar.
  • Individual admission prices during that regular season: 1,800 yen for adults, 700 yen for ages 6 to 15, and 350 yen for ages 3 to 5.
  • Prices differ by age. Families should group travellers by their actual ages before calculating the expected admission budget.
  • This information does not cover the official full-year opening calendar for 2027. Recheck the following year’s dates and applicable prices after the aquarium announces them.

Otaru Aquarium: Check the opening season before prices

Official information checked 2026-10-28. The table gives the aquarium’s regular 2026 operating information, not the rules for every year, special opening season or future year.

Item Information announced by the aquarium How to use it when planning
Regular 2026 opening season 14 March to 23 November Compare with your travel date; do not treat it as the 2027 calendar
Individual adult ticket 1,800 yen Reference price for regular operations in 2026
Individual ticket for ages 6 to 15 700 yen Apply the listed child category according to actual age
Individual ticket for ages 3 to 5 350 yen Apply the listed preschool category according to actual age

This table deliberately places the applicable dates before ticket prices. If you are checking a different year or a separately announced special opening season, the regular 2026 ticket prices alone are insufficient for planning. Check each age category separately rather than assuming one price for all children.

Aquarium and central Otaru: Half a day or a full day?

The main distinction between half-day and full-day plans is how much you intend to include in one travel day. The following are editorial planning frameworks, not packages offered by the aquarium, nor do they mean that travel time for every segment has been verified.

Planning pattern Main activity What to address first Misunderstanding to avoid
Aquarium-focused half-day Make the aquarium the main visit Confirm the current opening schedule and age-based tickets Do not squeeze city attractions into a fixed timeframe before checking transport
City-focused half-day Focus on central Otaru and consider the aquarium separately Assess whether there is enough time for another destination Do not assume that every attraction in Otaru is within walking distance of the others
Full day at aquarium and in town Plan the two areas separately, then check return transport and same-day travel Establish two activity segments, then check connections and opening hours Do not assume “day trip” means all attractions use the same opening hours

If the aquarium is the focus, confirm the aquarium’s notice applicable to your travel date before adding city attractions. If it is an optional extra, check whether your city itinerary leaves a suitable transport segment. Neither approach allows you to infer the time from Otaru Station to the aquarium from its admission table.

Travelling with children: How to check ticket prices

Otaru Station () is a useful name when planning local transport, but the ticket price table does not include connection timetables between the station and aquarium. Calculate admission costs and check transport separately.

Check Information established in this article Information to confirm separately
Travellers’ ages Separate individual prices for ages 3 to 5 and 6 to 15 Updated rules for other years and categories
Adult ticket Individual regular-season ticket costs 1,800 yen in 2026 Actual price in the following year
Visit dates The regular 2026 season has confirmed start and end dates Current calendar and any temporary changes
Transfers between town and aquarium Treat transport as a separate segment Actual services, valid passes and journey times on your date

You can begin estimating admission from these age categories, but do not combine transport tickets and admission tickets into one assumed charge. When travelling with children of different ages, distinguishing fare categories is more useful than relying on an undated total price.

How to plan a family visit

  1. Check the date first. Compare your visit with that year’s official operating information. This article confirms only the regular 2026 season.
  2. Then check tickets by age. Look up the appropriate adult, 6-to-15 and 3-to-5 prices separately.
  3. Choose the main destination. Allocate a visit to the aquarium if it is the focus; if town is the main destination, treat the aquarium as a separate area.
  4. Finally check transport. Confirm actual return routes, services and passes through the latest operator announcements, not the admission table.

Notes

The complete 2027 operating calendar has not been verified in this article. The regular 2026 dates and prices cannot automatically be applied to the following year. Admission, operating dates and transport services may change, so check the official website again before leaving.
