Beluga Performance Pool
A pool featuring diverse performances by the only beluga whales housed in western Japan. Highlights include the "Happiness Bubble Rings®", formed from bubbles released from the blowhole, and the Happiness Magic Rings, a large, swirling ring created through powerful breaths.

Up-Close Views of Flying Penguins
Seen from below, penguins appear to soar through the sky as they swim overhead. A small viewing window offers a unique underwater perspective. In the newly renovated indoor pool, simulated snowfall creates a more natural environment, allowing for even more vivid observations of their behaviour.

Reopened in March 2022
Renovated under the theme "Aquas Iluminated by Light", this newly reopened space features a captivating fusion of marine life and projection mapping. Among the highlights is the striking collaboration between beluga whales and immersive visual effects.
