Tokyo Sea Life Park

Visiting Tokyo Sea Life Park
Tokyo Sea Life Park is open and operating normally today. A full replacement aquarium is under construction on the adjacent site and is officially scheduled to open in September 2028; the current facility will close only after the new one opens and its animals are transferred, and Tokyo Metropolitan Government has not yet finalized an exact closure date. The current glass-dome building will be preserved afterward, with its future use still under study.
Set inside Kasai Rinkai Park in Edogawa, eastern Tokyo, the aquarium is centered on the Voyagers of the Sea, a large ring-shaped tank with 360-degree central viewing that was Japan's largest indoor tank when it opened. The aquarium opened October 10, 1989, timed to mark Ueno Zoo's centennial, and its distinctive glass dome was designed by architect Yoshio Taniguchi.
Tokyo Metropolitan Government's redevelopment project is genuinely underway: a consortium including Oriental Land Co. and Taisei Corporation signed a contract in December 2022 to design, build, and operate the new facility. Construction is scheduled for completion by March 2028, ahead of the confirmed September 2028 opening. None of this affects a visit today. The aquarium remains a well-regarded, inexpensive eastern Tokyo family attraction worth visiting now.
General admission is ¥700, among the least expensive aquarium tickets in Tokyo, and the aquarium pairs naturally with the rest of Kasai Rinkai Park or with a Tokyo Disney Resort day, given the short train connection between the two.
