Extended due to overwhelming enthusiasm
Since its launch, "Slime Wonderland" has been bustling with many visitors every day.
At the venue, children are seen engrossed, forgetting the time, and many voices express sentiments like "It's more fun than I imagined" and "I want to come again."
Due to this overwhelming response, the event has been extended until April 11, beyond the initially planned date (until April 6).
This "experience that can only be had here" will now be available for longer.
Further evolution. Opening at 10 AM from April 1st
Along with this extension, operating hours have also been updated.

Absolutely impossible at home! A "full-body" slime experience
The biggest reason this event is supported is the ability to "experience slime with your whole body."
It's not just about touching. By immersing themselves in slime using their arms, body, and the entire space, children naturally become engrossed and drawn into play.
The scale and freedom that cannot be replicated at home define the value of this experience.

At the venue, a "continuous play" experience unfolds, integrating multiple activities.
・Slime waterfall flowing from above

It's not just one activity. With different ways to play at each spot, it's designed to be enjoyed repeatedly.
Play freely. The ways to enjoy it expand again and again.
Affordability starting from 900 yen is also attractive
