and ST to Hold "Gachapin & Mukku Everyone's Friend Day" Collaboration Campaign Starting April 2, 2026!

And ST Co., Ltd. (Headquarters: Shibuya 2-21-1, Shibuya-ku, Tokyo; President & CEO: Yuya Sakurai), which operates the mall & media business and produce business within the And ST HD Group, will participate in the "Gachapin & Mukku Everyone's Friend Day" project, planned by Fuji Television Network, Inc. and Fuji Consumer Products LLC, and will hold a collaboration campaign starting Thursday, April 2, 2026.

"and ST" is a platform that promotes fashion and lifestyle possibilities and their appeal by developing OMO (Online Merges with Offline) stores that fuse the benefits of web stores and physical stores, under the message "Fun, for Everyone, Starts Here." This time, the decision to participate in the "Gachapin & Mukku Everyone's Friend Day" project was made because the platform's aspiration to create a place where everyone can freely enjoy and connect through fashion aligns with the long-cherished motto of Gachapin & Mukku, "Everyone's Friend." By merging the warm worldview of the characters with the sensibility of "and ST," we will spread a new circle of "fun" from Harajuku.

The collaboration campaign will feature the sale of collaboration items with popular characters including Gachapin & Mukku. At "and ST TOKYO" in Harajuku, experiential content will be developed under the title "Everyone's Friend Surprise Grand Operation" to celebrate Gachapin & Mukku's birthday on April 2nd. Additionally, an SNS campaign will be held to present "and ST x Gachapin & Mukku Everyone's Friend Day" collaboration items. ■and ST x Gachapin & Mukku Everyone's Friend Day "Everyone's Friend Surprise Grand Operation" Overview Campaign Period: Thursday, April 2, 2026 – Wednesday, April 22, 2026 Campaign Stores: and ST TOKYO (1F, WITH HARAJUKU, 1-14-30 Jingumae, Shibuya-ku, Tokyo)
