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 within the JTB Group, has partnered with the musician group "Yabai T-Shirts Ya-san" (commonly known as YabaT) and their agency, BADASS Inc., to produce 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.

Sparked by Member Koyamata Kuya's X Post

A certain post by member Koyamata Kuya on X became a hot topic among fans (nicknamed "customers") and caught the attention of JTB Publishing's official 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 "Attractions of Tank-top Festival for Moms and Dads (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 stories from on-site coverage will be shared. This will promote not only the Tank-top Festival itself but also the "Shima City travel experience," one of the accompanying attractions, together with the YabaT members.
