Sumida Aquarium has shorter hours on June 5 and June 24
The aquarium inside Tokyo Skytree Town will close earlier than usual on two June dates because of private bookings.
Sumida Aquarium has posted two June early-closing dates on its official site. On Friday, June 5, 2026, the aquarium closes at 17:30 with last entry at 16:30.
A second shortened day is listed for Wednesday, June 24, 2026, when the aquarium closes at 17:00 with last entry at 16:00. Both changes are due to private use of the facility.
If you are planning an Oshiage or Tokyo Skytree Town visit, this is an important schedule change because late-afternoon and evening entry will not be available on those dates. Check the official site again before going in case the notice changes.
