Okinawa Churaumi Aquarium

The Churaumi Aquarium is the sight that most first-time visitors to Okinawa put at the top of their list, and it deserves the place. The centrepiece is the Kuroshio Sea, a tank so large that whale sharks and manta rays share it with schools of tuna and other open-water fish, and the viewing window is wide enough that you can sit and watch the whole scene as if you were standing on the sea floor. Around it, the galleries move from shallow coral reef to deep-sea species, with touch pools, sharks and a hall of colourful tropical fish. Outside, the aquarium grounds hold the Dolphin Lagoon with its free shows, a sea turtle pool and a manatee pool, and the whole complex sits inside Ocean Expo Park, a seaside park with beaches, gardens and walking paths that makes a full day of it.

Plan for a long morning or a full day. The aquarium itself takes two to three hours at a relaxed pace, and the outdoor areas and the rest of Ocean Expo Park easily fill the rest. In the off season the main building runs from morning to early evening with last admission an hour before closing, and in the busiest holiday and summer periods it stays open later.

The aquarium has no scheduled closing days through the end of March 2027, although it can close briefly for typhoons or other unforeseen events, so check the aquarium website if the weather is rough. The dolphin show, turtle pool and manatee pool are outdoors and finish earlier in the day than the main building, so see those first if you arrive in the afternoon.

Getting there is the main decision. The aquarium is on the Motobu Peninsula, a drive of roughly two hours from Naha without heavy traffic, and a rental car is the easiest way to combine it with Kouri Island, Nakijin Castle and the north coast. Long-distance buses also run from Naha and from the airport to the park, but the journey is slow, so leave early. Many visitors stay overnight in the Motobu or Nago area to avoid a long day on the road, and several beach resorts are within a short drive.

Make the most of the main tank by arriving soon after opening, when the halls are quieter, or in the last couple of hours before closing, when day-trip coaches have left. Whale sharks are fed at set times that are posted at the entrance, and the feeding talks at the Kuroshio Sea are worth timing your visit around. A lunch or coffee at the cafe overlooking the sea is a pleasant break before heading out to walk the park or the nearby Emerald Beach.
