Sumida Aquarium will shorten hours on June 24 and July 7 because of private bookings
The aquarium will close at 17:00 on June 24 and 18:00 on July 7, with earlier last-entry times on both dates.
Sumida Aquarium has posted two upcoming changes to its closing time because of private bookings. The notice says the aquarium will close at 17:00 on Wednesday, June 24, 2026, with last entry at 16:00.
A second change is scheduled for Tuesday, July 7, when the aquarium will close at 18:00 and stop entry at 17:00. Both notices are shown together on the aquarium’s official site.
For people planning a late-afternoon or evening stop in Tokyo Skytree Town, this is a simple but important schedule update. If you were planning to enter after the usual afternoon window, it is safer to arrive earlier or choose another day and check the latest official notice before you go.
