Okinawa Churaumi Aquarium is one of Japan’s most celebrated marine attractions, famous for the giant Kuroshio Sea tank, whale sharks and manta rays. Located in Ocean Expo Park on Okinawa’s Motobu Peninsula, it makes an excellent family day out and an opportunity to learn about the diverse marine habitats surrounding the Ryukyu Islands. This guide explains current admission, opening hours, transport and what to see.

Why Visit Okinawa Churaumi Aquarium?
The Kuroshio Sea tank
The centrepiece is an enormous display inspired by the Kuroshio Current, featuring whale sharks, manta rays and other large marine species. The wide viewing window gives the impression of looking directly into Okinawa’s offshore waters. Find a comfortable viewing spot and spend time observing animal behaviour rather than rushing past for one photograph.
Coral reefs and tropical marine life
Okinawa’s warmer waters support coral reefs and exceptionally diverse fish. Aquarium exhibits highlight reefs, life cycles and the environmental pressures affecting coastal ecosystems. For travellers interested in marine conservation outdoors, consider a separate trip to the Kerama Islands or the beaches beyond Okinawa’s main city areas.
Deep-sea exhibits
Some displays introduce animals adapted to the dark, high-pressure environment of deeper ocean waters. They offer a fascinating contrast to brightly coloured coral species and show how varied life in the surrounding seas can be.
Tickets and Opening Hours for 2026

|---|---|
| Adults | ¥2,180 |
| High-school students | ¥1,440 |
| Elementary and junior-high-school students | ¥710 |
| Children under six | Free |
These are official published standard rates, and group or disability-related concessions may apply. Confirm eligibility and changes at the aquarium’s official ticket page or Ocean Expo Park’s official fees page.
Normal and extended operating hours
The regular schedule is 8:30 a.m.–6:30 p.m., with last admission an hour before closing. In 2026, specified holiday weeks in spring and July operated until 8:00 p.m., while August offered hours until 9:00 p.m. These special periods should not be applied to ordinary October visits. The official aquarium says it has no scheduled closure through March 31, 2027, but extreme weather, including typhoons, can cause temporary closures.
Wednesday partial closures in Ocean Expo Park
During a trial period from July 2026 through March 2027, some Ocean Expo Park facilities are closed on Wednesdays for maintenance while the aquarium, dolphin area and several other facilities remain accessible. If you plan a whole-park visit, check the park’s facility-specific opening information rather than assuming everything will be available.
How to Get to Okinawa Churaumi Aquarium
Driving from Naha
A rental car is a popular option for exploring northern Okinawa because it allows flexibility for scenic and cultural stops. From Naha, the aquarium is often around a two-hour journey or longer depending on traffic and your starting point. Keep additional time for parking, walking from the car park and rainy-weather conditions.
Public transport and bus services
Bus routes connect Naha and other areas with the Motobu region. Confirm the actual service, final stop and journey time using current bus schedules; not all buses stop directly outside the aquarium. Public transport often takes substantially longer than driving, so avoid scheduling a tight onward connection.
Combined northern Okinawa day trip
Consider combining Churaumi with Kouri Island and Busena Marine Park if you have your own transport and enough daylight. These are separate attractions, not all within the Ocean Expo Park grounds.
Things to Do in Ocean Expo Park
See the dolphin area
Ocean Expo Park has marine-animal experiences outside the main aquarium building. The location and availability of talks or demonstrations can change, and their operating hours differ from those of the aquarium. Check the timetable on arrival rather than relying on historic feeding times quoted by older websites.
Explore Emerald Beach and coastal viewpoints
The park’s coastal setting is attractive even when you are not interested in every exhibit. Follow posted beach-safety warnings and swimming-season rules. There are also gardens and cultural exhibits, though some facilities close for scheduled maintenance.
Marine culture and island history
Extend the day by learning about Okinawa’s wider history. In Naha, Shuri Castle represents the former Ryukyu Kingdom, while Okinawa Prefectural Peace Memorial Museum offers sobering twentieth-century context on a different itinerary.
Practical Tips for Families and Photographers
- Allow extra walking time from the nearest parking areas, particularly with small children or older travellers.
- Respect aquarium photography rules and avoid using flash where prohibited.
- Plan meal breaks before peak lunchtime if travelling during school holidays.
- Do not promise children a specific feeding show: animal-welfare and operational needs can change the programme.
- Check typhoon warnings and road conditions during the tropical storm season.
- Conserve time for the large tank rather than spending the full visit in gift shops.
Other Okinawa Attractions for a Longer Trip
Nature lovers can explore Route 58 for an island road-trip perspective, or look at Nakagusuku Castle for historic architecture in central Okinawa. For a sombre history day, visit Himeyuri Memorial Tower in the south.
Island travellers may enjoy the Yaeyama Islands, Taketomi Island or Ishigaki Yaima Village, but these require different flights or ferry arrangements and should not be mistaken for places near the aquarium. If you are researching other Japanese aquariums, compare Osaka Aquarium Kaiyukan and Port of Nagoya Public Aquarium.
