Sendai Umino-Mori Aquarium's "THE WAKEY AQUARIUM" Collaboration Continues Into Fall With "Colorful Sea Party" From August 31

Sendai Umino-Mori Aquarium, a facility built around creating new connections between people and the sea, is hosting "THE WAKEY AQUARIUM," the first collaboration event of its kind at an aquarium anywhere in Japan, together with "The Wakey Show," an edutainment show that explores science, nature, and art through songs, dance, and games, from July 17 (Friday) through October 18 (Sunday), 2026.

From August 31 (Monday) to October 18 (Sunday), the aquarium is hosting "THE WAKEY AQUARIUM Colorful Sea Party," packed with experiences found nowhere else — from a special collaboration version of "Sparkling of Life," where about 25,000 Japanese sardines move in dynamic schools, to a colorful stamp rally collecting stamps of the Wakeys characters placed throughout the facility. Visitors can watch, learn about, and play with sea creatures, making it a special time for the whole family to create memories together.

The event brings the charm of the ocean to life alongside the Wakeys, the main characters of "The Wakey Show." Since the content changes between the summer and fall runs, visitors can enjoy something new no matter how many times they come.

Sparkling of Life – THE WAKEY AQUARIUM Edition

In the large tank "いのちきらめく うみ," which recreates the rich waters of Sanriku, about 25,000 Japanese sardines take the lead role in "Sparkling of Life," a premium show known for its dynamic schooling movements — now in a special collaboration version. The tank, 14 meters wide and 7.5 meters deep, is home to around 50 species and 30,000 animals, including Japanese sardines and hoshiei. With no roof, natural sunlight pours directly in, bringing out the animals' true, vivid colors.

Set to "Bun Bun Bun!," a song from "The Wakey Show," the sardines swim gently at times and energetically at others, captivating visitors with their fluid, synchronized movements.

Don't miss this collaboration, available only here.

Note: Popin, ヴィーテ, and ドーネ appear by voice only.
