Exciting Collaboration Event Between 2.5D Singer Group Ireisu and RED° TOKYO TOWER Announced

Unique Collaboration Event to Captivate All Ages

The exciting fusion of the 2.5-dimensional singer group Ireisu and RED° TOKYO TOWER has been officially confirmed! This first-ever collaboration event will take place from August 1 to August 31, 2025, at one of Japan's largest digital amusement parks located right beneath the iconic Tokyo Tower. Aimed at entertaining children and adults alike, this event promises an unforgettable experience designed for fans, puzzle lovers, and interactive event enthusiasts alike.

A Journey Through Time and Mystery

The highlight of this event will be an immersive mystery adventure that allows participants to slip back in time to 1950s Tokyo alongside the members of Ireisu. This original storyline invites you to step into a different era, embarking on a puzzle-solving journey in a nostalgic Tokyo that existed before the Tokyo Tower was built.
Imagine arriving in present-day Tokyo Tower only to find yourself in the charming and somewhat familiar atmosphere of 1950s Tokyo. Participants will play the role of the story's protagonist as they join Ireisu to uncover mysteries and navigate their way back to the modern day.

To enhance this remarkable story, unique illustrations created specifically for this event will be showcased, highlighting retro styles from the 1950s. The artwork features classical color palettes and detailed Showa-era fashion, beautifully encapsulating a blend of the past and contemporary tastes. Giant visuals, along with life-sized panels adorned with these exclusive illustrations, will be strategically placed across the venue, captivating attendees with original visuals that are only available during this event.

Original Beverages Inspired by Each Member

During the event, unique, original drinks crafted by each Ireisu member will take center stage. Each beverage reflects the personality and creativity of the members, ranging from imaginative names to vibrant flavors. For instance, Riu’s drink boasts the confident name, “The Secret Behind My Genius? Drink This and Know All!” In contrast, -hotoke- offers a refreshing “This Will Take You to Pure Bliss!! Namu Namu Iimuimu Sky Blue!” Initial Rabbit presents a quirky “It’s White but Purple and Well, It Works!” while Naiko entices with the “Sugar Level MAX Pink Lemon Calpis” that promises a memorable experience. Iff's drink is designed for busy individuals, titled “Salaryman Energy Drink – Unlimited Stress Cider.” Lastly, Yusuke presents a refreshing summer twist with his drink, “I’ll Be This Color if I Tan,” perfectly echoing the vibe of a hot summer day at Tokyo Tower.

Additionally, each drink comes with a randomly selected retro-style record cover coaster featuring illustrations from the event, creating a nostalgic atmosphere reminiscent of a vintage music café.

Limited Edition Goods and Exclusive Benefits

Fans can look forward to exclusive merchandise featuring the special illustrations. Items such as acrylic stands, stickers, multi-cloths, and acrylic keychains will add a nostalgic flair to daily life, made available only at this event. A selection of Ireisu's official merchandise will also be available for those who are yet to get their hands on essential Ireisu items.

For every purchase over 2,000 yen, attendees will receive a randomly distributed “Teen Magazine Style Postcard.” This postcard, designed to evoke nostalgia reminiscent of showa idol magazines, integrates modern sensibilities into its aesthetic.
