A Slime Park Where Play Takes Center Stage
Slime Wonderland, a limited-time interactive slime park, is opening at WHATAWON in Kishiwada, Osaka, running for 11 days from March 25 (Wed) to April 4 (Sat), 2026. Entry starts from ¥900 for 30 minutes, making it an accessible activity for families.
The experience invites visitors to touch, mix, and play with squishy slime across a variety of interactive content areas, designed so that both kids and adults can wander through and enjoy at their own pace.
A Full-Body Slime Experience


Rather than a passive "watching" event, Slime Wonderland is designed for active participation. Visitors can feel the unique textures of the slime, mix different varieties together, and explore the space at their own leisure—making it a naturally photogenic environment as well.

Slime Wonderland offers flexible session lengths to suit your schedule:
- 30 minutes: ¥900

- Extension (10 minutes): ¥250
Cashless payment only.
