From August 17th (Monday) to September 24th (Thursday), we will be selling tickets that offer a 50% discount on admission for up to 5 accompanying junior high school students or younger for customers entering between noon and 4pm, for one adult or high school student. We will also be selling tickets that offer a discount on admission for the second and subsequent people for groups of two or more adults or two or more high school students entering after 5pm.

The summer-only event currently underway, "Sumisui Fireworks 2026 ~A Summer of Cooling with Water and Light~," has been extended and can be enjoyed until September 24th (Thursday). In addition, the projection mapping of fireworks themed after aquarium creatures, which is usually projected only at night during the event, will be shown during the daytime as well from August 17th (Monday) to September 24th (Thursday).

During the period leading up to Silver Week, when the lingering summer heat continues, we encourage you to enjoy a refreshing summer moment woven together by water and light with your family and friends.
