Okinawa Churaumi Aquarium

**Overview** If rain catches you in northern Okinawa, make the main aquarium building the outing. Start with the reef tanks near the entrance, then follow the floor plan down to the Kuroshio Sea tank and the deep-sea galleries. The building recreates a descent through local waters, so take time to compare the animals and habitats on each level. Leave the outdoor dolphin and turtle areas for a break in the weather. Check the park calendar and your approach from the parking lot or bus stop before setting out. **Key metrics** - Standard aquarium hours: 08:30–18:30 - Standard last admission: 17:30 - Kuroshio Sea tank volume: 7,500 m³ - Exhibit tanks: 75 **Pros** - The principal marine exhibits are inside one building. - The Kuroshio Sea tank and deep-sea rooms offer a substantial northern outing. - The official floor guide makes it easy to shorten or extend the visit. **Cons** - Motobu is a long trip from Naha. - The approach from some parking lots or bus stops is exposed. - Nearby outdoor exhibits have separate hours. **Best for** Visitors in Motobu or northern Okinawa who want a sheltered visit with substantial marine exhibits. **Things to watch out for** Check last admission and the park calendar. Plan the walk to the aquarium entrance and use the indoor floor map during persistent rain.
