Sunshine Aquarium's Refreshing Summer Festival 2025
This summer, Sunshine Aquarium in Ikebukuro, Tokyo is set to host its much-anticipated event, the "Sunshine Aquarium Refreshing Summer Festival 2025" from July 18 (Friday) to August 31 (Sunday). With temperatures soaring beyond 35°C, this festival promises an exhilarating escape from the heat.
Special Seal Training Show
A highlight of this event is the special summer edition of the seal training show, dubbed the "Splish-Splash Seal Operation!". Every day at 2:00 PM, spectators will be treated to an exciting performance featuring seals and plenty of water effects. On particularly hot days exceeding 35°C, the show transforms into the "Super Splish-Splash Operation!" with increased water levels, creating an interactive experience in the designated "Drenched Area" where guests can expect to get wet.
In addition to the shows, a team known as the "Festival Mist Squad" will appear in the outdoor Marine Garden area, equipped with water tanks to spray mist on visitors looking for a refreshing respite from the heat. Keep an eye out for this team as they sporadically pop up throughout the festival to bring cool relief to guests!
Explore and Learn with Guide Tours
The festival also features daily "Exploration Guide Tours: Special Edition for Summer Break Research". These guided tours will cater specifically to elementary school students and include materials useful for summer homework. Participants will receive specially designed certificates to commemorate their experience.
The tours take place at 11:00 AM and 2:00 PM, lasting about 40 minutes each. Notably, the content may vary depending on whether the focus is on marine mammals or fish, providing upcoming marine scientists a chance to learn about their favorite creatures.
