Emerald Beach

**Overview** You can build a whole day around Emerald Beach and stay within Ocean Expo Park. The beach occupies a lagoon and gives mixed groups a place to spend time outside after a visit to Churaumi Aquarium. The park guide maps separate places to play, rest and enjoy the view. The operator names the Emerald Gate garage as the closest parking and publishes a separate swimming window. That distinction is worth checking if you plan to visit the aquarium first and leave the water for later. **Key metrics** - 2026 season: Apr 1–Oct 31 - Listed 2026 swim hours: 08:30–17:00 - Beach admission: ¥0 - Walk from Haisai Plaza: 1.2 km **Pros** - A defined swimming area is useful for family planning. - Aquarium, beach shops and other park stops are nearby. - The park lists free access to the beach. **Cons** - The 2026 bathing season ended on October 31. - The park’s opening hours and the beach’s swimming hours differ. - The lagoon is a swimming-first stop for this ranking. **Best for** Families visiting Churaumi Aquarium who want an easy same-day swimming option in season. **Things to watch out for** Head for P9 Emerald Gate if the beach is your first stop, and check the operator’s swimming notice before committing to an afternoon swim.
