[Special]Exciting Adventures in Heiwajima! A Playground the Whole Family Can Enjoy

「Tondemi Heiwajima is an indoor athletic facility located within the BIG FUN Heiwajima shopping complex, operated by Keikyu Kaihatsu. Packed with hands-on activities for both kids and adults, it’s the perfect spot for an action-filled day. To celebrate its 6th anniversary, the facility underwent renovations in July 2024—making it even more fun than before!


In this special feature, we’ll share firsthand experiences from a parent and children visiting Tondemi Heiwajima for the very first time!

A family’s first adventure at Tondemi Heiwajima


Operated by Bandai Namco Amusement , Tondemi Heiwajima spans three floors, offering a full-scale athletic experience.
This time, a family from Ota City took on the Tondemi challenge—a third-grade boy, his sixth-grade sister, and their mother.


First-time visitors must complete a membership registration. To make check-in smoother, it’s best to register in advance using a smartphone. The facility operates on a two-hour rotation system, so booking ahead is recommended to avoid long waits.*Operating hours may vary at other locations.


For safety reasons, certain areas—such as the trampoline zone—require special Tondemi socks with anti-slip soles. These socks are provided upon payment of the 600-yen membership registration fee. Once everyone is geared up, it’s time to jump into the fun!

Jump to your heart’s content in the Trampoline Area

Our first stop was Japan’s largest Trampoline Area, featuring 54 trampolines spread across an impressive 660 square meters.



The space is divided into different zones, each designed to maximize the fun of trampolining with unique interactive features!

The children bounced around with excitement, trying again and again. With every jump, they felt a rush of exhilaration—almost as if their physical abilities had suddenly skyrocketed!

A heated time attack on the air run



Next, we took on the 40.7-meter-long air run course, dodging inflatable obstacles along the way as we raced toward the finish line.

At the sound of the starting signal, the sibling showdown began!



The course featured sections where you had to slide down, jump over, and crawl under obstacles to keep moving forward.


*We obtained special permission to take photos inside.
At the finish line, a monitor displayed their times. Seeing their results only fueled their determination, and the children eagerly raced through the course again and again!

Tackling heights on the climbing wall

Our next challenge was the Climbing Wall Area , which boasts 14 types of walls and 19 different courses. After putting on our harnesses and helmets, we were ready to go!



With six levels of difficulty, we started with the easiest walls to build confidence before taking on more challenging ones.



Before starting, the children were brimming with confidence, saying, “I’m totally fine with heights!” But once they got up there, they nervously admitted, “This is scarier than I thought...”

Still, the thrill of reaching the top and pressing the finish button was unbeatable! With each success, they were eager to take on new walls one after another.


They also tackled a wall with rotating platforms (top photo) and another with hanging ropes (bottom photo)!

This is digital climbing, an exciting fusion of projection mapping and sensors. Players can enjoy interactive games, such as territory capture battles.
One activity that particularly stood out in the Climbing Wall Area was this giant, eye-catching structure—an adventure that looked unlike anything we had ever seen before.



The younger brother took on the challenge of climbing higher and higher poles, carefully stepping up one at a time.



He refused to give up—and in the end, he successfully reached the tallest pole!

Thrilling drop! The vertical slider

One of the must-try attractions in the Climbing Wall Area is the Vertical Slider.



Holding on tightly to the bar, you’re lifted straight up to the highest point—then, in an instant, you slide back down in one exhilarating drop!





The younger brother gave it a go, too! It was a heart-pounding experience, but once he landed, he beamed with excitement and said, “That was so much fun!” There’s an additional fee of 500 yen to try this attraction, but it’s absolutely worth it at least once!

An aerial adventure on the ropewalk

Next, we headed to the Slackline Area , where we geared up with harnesses and took on a challenge suspended 3.5 meters above the ground.



With two different routes varying in difficulty, we carefully balanced our way across the swaying platforms, just like tightrope walkers.



The grand finale? A zip line that sent us soaring 18 meters through the air in one smooth ride! The rush of cutting through the wind was exhilarating, and as soon as we landed, everyone was grinning and saying, “Let’s do that again!”

The TONDEMI Party Area —a huge hit!

The TONDEMI Party Area offers seven different exciting activities, all packed with party-style fun. The kids were beyond excited to try out games they had only seen on TV variety shows!


Poka Poka Stadium : A balance battle where you try to knock your opponent off the platform using a padded pole.

Jump Twister: Jump and duck to dodge rotating bars.

Quick Push Room : Race against the clock, pressing as many glowing buttons as possible to score points.
This area is not just about fun—it’s also a great way to get active and release some energy!

Tondemi Waiwai Carnival Area

Our final stop was the Tondemi Waiwai Carnival Area, a brand-new addition introduced in 2024. A unique perk of this area is that it opens one hour before the rest of the facility, allowing early visitors to start playing right away—no waiting required!

The kids especially loved the Human Tower Battle .



In this activity, players strike their favorite poses, which are then turned into “human blocks” and stacked into a towering structure. But be careful—if the tower loses balance and collapses, the game is over!

We all brainstormed fun poses to try next, and even the reporter and camera operator accompanying us couldn’t resist joining in. Everyone laughed as we stacked the blocks higher and higher!



With creative, interactive experiences in every area, Tondemi Heiwajima is a place where both kids and adults can fully immerse themselves in play. And even after all that, there was still more fun left to explore!

During our visit on a weekday evening, the facility wasn’t too crowded, making it a great time to visit if you prefer a more relaxed experience.



*For safety reasons, Tondemi has height and weight restrictions. However, there is a dedicated kids’ area for children over 2 years old who do not meet the main attraction requirements. For more details, please check the official website.
