“NO LIMIT!” Heatstroke Prevention: Aiming for “Zero Heatstroke” and Making This Summer Even “COOLER” – Universal Studios Japan and Japan Weather Association Co-Host “Heatstroke Prevention Seminar & Experience Lab” Today

This summer, Universal Studios Japan is not only offering exciting special events to help guests beat the heat in a “COOL” way, but is also seriously committed to ensuring all guests can enjoy their summer visit safely and comfortably by actively promoting various innovative heatstroke prevention measures across the park, aiming for “Zero Heatstroke.”

This morning, in collaboration with the Japan Weather Association’s “Zero Heatstroke” project, the park hosted a “Heatstroke Prevention Seminar & Experience Lab,” welcoming approximately 100 sixth-grade students. The seminar, led by Japan Weather Association meteorologist Tomoko Kubo, covered this summer’s heat trends, heatstroke prevention, and practical countermeasures. Afterwards, students experienced the cooling effects of evaporation through “mizuage” (water sprinkling) and mist systems in various park areas, including “Cool Splash Time” and “Cool Green Street.” With summer vacation approaching, the elementary students learned through fun experiments and hands-on experiences—content they can also use for their summer vacation independent research projects—making this a unique initiative suited for the intense summer season.

On this day, just before summer break, participating elementary students gathered with their worksheets in hand. During the seminar led by meteorologist Tomoko Kubo, they learned clearly about this summer’s heat patterns and effective heatstroke prevention strategies. After understanding “why it’s hot” and “how to prevent it,” they moved into the park, where they experienced the sudden drop in temperature upon entering the mist-filled “Cool Green Street.” During “Cool Splash Time,” as music played and water was simultaneously released, students experienced the mechanism of evaporative cooling in a real-world setting, gaining firsthand understanding of how it leads to a cooling effect.

Elementary participants thoroughly enjoyed the park-exclusive “COOL” programs with entertainers and crew, sharing feedback such as: “Getting completely soaked was even more refreshing than I imagined!” “I could clearly feel the big temperature difference with and without mist!” and “Now I understand the tricks to staying cool!”

Additionally, the “Experience Lab Worksheet” will be available for free download from the Universal Studios Japan corporate website throughout the summer event period (until Wednesday, August 26, 2026). This initiative allows guests to personally verify “extreme heat countermeasures”—a major summer challenge—through their own eyes and feet, making it an accessible activity that families and friends can enjoy together at the park.

The Japan Weather Association-supervised “Experience Lab Worksheet” can be downloaded for free via the URLs below. Feel free to use it for summer vacation research projects.

In recent years, rising summer temperatures have heightened the importance of heatstroke prevention for park guests. While implementing various heat countermeasures, the park has also introduced newly designed worksheets this year to turn the summer park experience itself into an opportunity for “learning.” This summer, we will further strengthen heatstroke prevention efforts across the entire park, aiming for “Zero Heatstroke.”

Event Overview

Event Name: “Zero Heatstroke” Heatstroke Prevention Seminar & Experience Lab (in cooperation with the Japan Weather Association)

Schedule: July 14, 2026 (Tuesday)

Participants: Approximately 100 sixth-grade students

Program:

① Heatstroke Prevention Seminar / Instructor: Tomoko Kubo, Meteorologist, Japan Weather Association

② “Experience Lab” Program / Cool Green Street, Cool Splash Time

Participant Feedback (Sixth Graders)

“I could feel how only the misted areas instantly changed temperature, even in the heat. I realized we should think about these countermeasures for our research projects. I love Jaws, so I want to come back and visit many more times!”

“It was my first time measuring ground temperature, and I was surprised that the floor temperature dropped about 20 degrees just because of the mist.”

“After learning about how to avoid heatstroke in the seminar, going outside and actually experiencing it made it easy to understand and fun. I learned a lot! I could participate comfortably and enjoyably without tension, thanks to the friendly crew members.”

“It was so much fun! I liked that I didn’t feel like I was studying—I could learn while playing! I want to come back and get drenched in Cool Splash Time again!”

Last week, the rainy season ended, and the long-awaited summer vacation has finally arrived for children. While it’s a joyful season, how to deal with this heat has become a social issue. At Universal Studios Japan, we considered what we could do about this societal challenge, which led us to co-host this collaborative event with the Japan Weather Association.

With the hope of creating an opportunity for children to actively learn and think about heatstroke prevention themselves, we welcomed about 100 sixth-grade students today as an extracurricular activity. They discovered cooling techniques within the park and enjoyed them enthusiastically together. In addition to classroom learning, we introduced the “Experience Lab Worksheet” for the first time—participants write directly on the sheets while experiencing the park, deepening their learning. We hope children will use these worksheets not only for summer vacation research projects—a major hurdle for many—but also as a way to enjoy and learn simultaneously. We would be delighted if this became a “three birds with one stone” opportunity—learning, having fun, and completing their research. As many families will visit during the peak summer season, we aim to ensure guests enjoy the park to the fullest while also intensifying our heatstroke prevention efforts more than ever, striving for “Zero Heatstroke” and the sight of every guest’s happiest smile.

This was a valuable opportunity for children to learn about heatstroke through the joy of self-directed learning. I believe the children now recognize that heatstroke is not something that happens to others, but something that could happen to them, and that they need to be careful during summer.

Regarding the “worksheets” used today, I believe they will not only serve as summer homework but also become a starting point for children to share this knowledge with family members—parents, grandparents, and others—and encourage them to take preventive actions.

Today, many children were greatly surprised to experience firsthand in the park how much the temperature drops with mist: “It cools down this much!” Through such personal experiences, rather than feeling “I have to do it” as an obligation, they begin to think “I want to do it”
