Inside the huge tank "Kuroshio Sea", which exhibits superpower, is the world's largest whale shark, and the world's first successful artificial reproduction of ghost bat goblets . There is also the "deep sea" that fully embodies the ocean of Okinawa, recreating the mystery of the deep ocean of Okinawa. From April 2022, business hours are divided into normal period and busy period. 【Normal period】 08:30-18:30 (Last admission: 17:30) 【Busy period - December 29, 2022 to January 3, 2023】 08:30～20:00 (Last admission: 19:00) The hotel may change the dates of the busy period subject to the state of COVID-19 transmission rates. Moreover, the hotel may change the dates of the busy period if there are important events, etc. The aquarium will be closed on the first Wednesday in December and the following day (Thursday). On days other than the aforementioned days (including the beginning of the year and the end of the year), it is open to the public (unless there are unforeseen natural disasters e.g. typhoons). In that instance, the aquarium will close. In order to create a "safe, comfortable and clean" environment to welcome tourists, Okinawa Churaumi Aquarium will conduct maintenance and safety inspections of various facilities during the closed days. We seek your kind understanding on this matter. As the main aquarium building is far away from the parking lots, please cater sufficient time to allow for travelling to the main building from the carpark.
