An aquarium is one of the easiest days to sell to a family or school group: it suits every age, it works in any weather, and it is safe. The difference between a good visit and a crowded one is planning. Our Japan team covers the country's two best-known aquariums in its guide to Japan's aquariums for family and school groups. Here we look at how an agent should position and book the day.
Two Japan Aquariums Clients Ask For
- Okinawa Churaumi Aquarium. In the Ocean Expo Park on the Motobu Peninsula, in the north of Okinawa's main island. Its main tank holds whale sharks and manta rays. It is about two hours by road from Naha, so plan it as a full day.
- Osaka Aquarium Kaiyukan. On Osaka's bay, built around a central Pacific Ocean tank with a whale shark. Visitors walk down a spiral ramp around the tank, and it fits easily into a city day.
- The right one for the route. Most large cities and many coastal towns in Japan have a good aquarium. We choose the one that fits the itinerary rather than adding a long detour.

Who Buys It
- Families with young children, who need a day that holds everyone's attention without long walks.
- School and student groups, for whom an aquarium links naturally to science and the ocean.
- Multi-generation groups, because the large aquariums are mostly step-free, with lifts and wheelchair loans.
Timing Advice to Pass On
- Avoid the peaks. Weekends, national holidays, Golden Week, the summer holidays and the New Year are the busiest times. A weekday morning is the calmest.
- Feeding times and shows. Many aquariums run feeding sessions and dolphin or sea lion shows at set times. The visit should be timed around them.
- The rainy-day plan. An aquarium is a strong choice for a wet day, but every other visitor thinks so too. Expect crowds when the weather turns.

What to Check Before Confirming
- Group admission. Many aquariums offer a group rate for larger groups booked in advance. The conditions vary by aquarium.
- Education programmes. Some aquariums run short programmes for school visits. See our note on Japan educational and student groups.
- Coach parking. Some aquariums have limited coach space at busy times, so parking and the drop-off point are confirmed in advance.
