First in Japan! Amusement Park Whole Jack

Speaking of JO1 Ren Kawajiri's fandom "REN's BACKERS", that fan group has been running support advertisements in more than 40 places in Japan and overseas, and in March 2025, it created Japan's first wrapped airplane "Ren-kun Jet" with the participation of about 1,500 people, creating a huge buzz!

This year, we took on the challenge of further scaling up.

"#Renpa" named by "REN's BACKERS".

This word, which is a combination of "Ren-kun + Hirapa", quickly spread on SNS such as X, and related SNS posts have received over 1 million views in total! That's what he said.

Some people said, ``This will be my first ever 'Hirapa','' while others from JAM in the Kansai area said, ``New memories will be added to this memorable place.'' There are many calls on social media to find JAMs to visit the park with, and many interactions are seen on social media, giving a strong sense of anticipation for the project.

Interview with fan group "REN's BACKERS"

The company that made this Amusement Park Jack a reality wasREN's BACKERS” I had an interview with Mr.

Q1. Why did you choose "Amusement Park (Hirakata Park)" from last year's airplane wrapping this year?

The airplane wrapping project we conducted last year received a great response, and we were looking for a suitable content for our next project. However, it was not easy to find a project with a similar impact, and the study was at a standstill.

In such a situation, I learned of the announcement of a new project by Hirakata Park and Cheering AD. Mr. Kawajiri regularly appeals to fans at live performances and other events, saying, ``Please stay friends with JAM.''

Amusement parks are places where people gather and share fun times, symbolizing friendship. We chose this project because we thought that responding to his wishes and creating a place for fans to interact naturally would be the best gift of all.

Q2. Please tell us about your commitment to advertising design and planning.

Since this is a project to "jack up" the entire amusement park, we valued a pop and bright worldview. On the other hand, by incorporating classical elements such as gold frames, we show respect for the historic Hirakata Park and are conscious of a design that harmonizes with the atmosphere of the park.

The Ferris wheel uses Kawajiri's large visuals on all vehicles, and is designed to ensure that the experience of ``riding on a favorite gondola'' comes true. In addition, life-sized support boards installed at five locations within the park each have a QR code with a different link destination, in an effort to convey the appeal of Mr. Kawajiri even to those who are learning about him for the first time. Furthermore, by hiding icons of other JO1 members throughout the design, JAM members can enjoy discovering them.

We hope that everyone will enjoy the experience of ``looking for Lotus-kun'' in the park and share their memories on SNS. We hope that this post will be an opportunity to share the joy with those who are unable to visit the park and with fans overseas.

Q3. How many people participated in this project? Also, what was the reaction from the fans?

This project received support from approximately 1,300 people, and SNS posts related to the project received over 1 million views in total. There are many people who know the name of Hirakata Park but have never had the opportunity to visit it, and many people say, ``This will be my first time at Hirakata Park.'' We have also received positive comments from people in the Kansai area, such as ``creating new memories in a place with fond memories.''

After the project was released, there were multiple calls and interactions on social media to find JAM to visit the park together. This scene is exactly what we wanted to convey to Mr. Kawajiri. I feel that the fans deeply sympathize with Kawajiri-san's message of "JAM friendship" that he cherishes.

Q4. Please tell us the thoughts you put into the project.

First of all, we hope that this project will bring smiles not only to JAM people, but also to general visitors. I would be happy if you could get to know Ren Kawajiri and JO1 even just a little bit through the memories of the fun spring break we spent at Hirakata Park, and the photos and videos we took.

I hope that the message of "getting along" that Mr. Kawajiri values ​​will spread to more people through JAM's enjoyment of this project.

We would like to express our sincere gratitude to everyone at "REN's BACKERS" who united the thoughts of approximately 1,300 people and made this unprecedented project, Japan's first amusement park jack, a reality. “Cheering AD” would be happy if we could continue to help our fans make their wishes come true!

The posting period will be approximately one month from March 13, 2026 to April 8, 2026. This is a project where everyone who visits Hira Par during spring break will be able to encounter this special support advertisement.
