Collaboration Between "Rurubu" and "Yabai T-Shirts Ya-san" Realized Thanks to Member's SNS Post! "Rurubu Special Edition Tank-top Festival 2026" to be Distributed at Shima Spain Village Live Event

JTB Publishing Co., Ltd. (Koto-ku, Tokyo, President and CEO: Hiroyuki Morizaki), which provides travel and lifestyle information for the JTB Group, has partnered with the musician group "Yabai T-Shirts Ya-san" (commonly known as YabaT) and their agency, BADASS Inc., to create a guidebook for YabaT's private live event at Shima Spain Village in Mie Prefecture in May 2026. The collaboration was sparked by a post made by YabaT member Koyamata Kuya on X (formerly Twitter). The guidebook, titled "Rurubu Special Edition Yabai T-Shirts Ya-san 'Tank-top Festival 2026' in Shima Spain Village Official Guide," will be distributed to attendees.

■ Triggered by Member Koyamata Kuya's X Post

A certain post by member Koyamata Kuya on X became a hot topic among fans (known as "customers" by YabaT) and garnered a response from the official JTB Publishing X account. This led to an inter-industry collaboration between "Yabai T-Shirts Ya-san," who have been appointed as Shima City Tourism Ambassadors, and "Rurubu," which promotes regional attractions.

■ Elevating a Music Event into a "Family Travel Experience"

This event is designed with families with children in mind, and since the venue is a theme park, information will also be disseminated in collaboration with "Rurubu Kids," JTB Publishing's targeted web media. The site will feature an article titled "Appealing to Moms and Dads! The Charms of Tank-top Festival (tentative)," and official SNS will release reel videos about "Shima Travel with Children."

Furthermore, in collaboration with JTB Publishing's web media "Rurubu &more.," content that couldn't fit in the magazine and behind-the-scenes coverage will be shared, aiming to promote not only the Tank-top Festival itself but also the "Shima City travel experience" as one of the accompanying attractions, together with the YabaT members.
