The hands-on event Slime Wonderland, held at the entertainment mall WHATAWON in Kishiwada, Osaka, has been extended through April 11 following an enthusiastic reception that surpassed all expectations. Starting April 1, the venue also opens at 10:00 AM, giving visitors even more time to enjoy the experience.
Extended After an Unexpectedly Enthusiastic Response
Since its opening, Slime Wonderland has drawn crowds every day. Visitors — children in particular — have been spotted losing track of time, with many saying it was "even more fun than expected" and that they want to come back.
Due to this response exceeding initial expectations, the event has been extended from its original end date of April 6 to April 11.
Opening Hours Updated: 10:00 AM from April 1
Alongside the extension, the opening time has been updated. From April 1, the doors open at 10:00 AM, giving visitors a more relaxed window to enjoy everything the event has to offer.
This makes it easier for those who want to arrive early to beat the crowds, or simply spend a full morning at the event.
A Slime Experience You Can't Recreate at Home
The main draw of Slime Wonderland is the chance to experience slime with your whole body — not just your hands.
Rather than a simple touch-and-feel activity, participants can immerse their arms, body, and surroundings in slime, leading to a naturally engaging and absorbing experience. The sheer scale and freedom of the setup is something that simply cannot be replicated at home.
Slime Waterfall, Pool, Target Throwing, and Slime Making — All in One Venue
The event features multiple distinct activity zones, creating a continuous stream of fun:
- A slime waterfall cascading from above
- A slime pool you can immerse yourself in
- A target-throwing zone where you can launch slime freely
- A DIY slime-making corner to create your own original slime
Each zone offers a different way to play, keeping the experience fresh and entertaining throughout the visit.
Starting from ¥900 — Easy to Join, No Reservation Needed
No advance booking is required, so visitors can simply drop in on the day.
With the extension now in place, both spontaneous visits and planned trips are welcome. Entry starts from ¥900.
