Sun Hoseki’s Hoppe-chan Teams Up with Teen Influencer Group Mel Petit for a Hands-On Event in Shibuya on May 30

Sun Hoseki, operated by the Interactive Content Division of Memory-Tech Tsukuba Co., Ltd., announced a collaboration between its popular character Hoppe-chan and the junior and senior high school girl influencer group Mel Petit. As part of the project, a hands-on “fresh squeeze” workshop will be held on Saturday, May 30, 2026, at Village Vanguard Shibuya Main Store. Participants will be able to interact with Mel Petit members while creating their own original Hoppe-chan. Hoppe-chan, which captivated many children during the Heisei era, and Mel Petit, which is supported by girls in the Reiwa era, will come together in Shibuya to update the idea of “KAWAII” across generations. Hoppe-chan is a popular character born from Sun Hoseki, known for its rounded shape, gentle eyes, and whipped-cream-like silhouette. It gained popularity especially among elementary and junior high school students during the Heisei era. Mel Petit is a junior and senior high school girl influencer group active mainly on YouTube and TikTok under the concept “Start your kawaii!” Since launching video uploads in 2019, its YouTube channel has surpassed 431,000 subscribers and 650 million total views. Through content covering makeup, fashion, romance, dance, documentaries, and more, the group shares the real present of Gen Z and Generation Alpha. On the day of the event, selected Mel Petit member Kokomin will appear as one-day store manager. Participants can experience making original Hoppe-chan items at the venue, including exclusive Mel Petit-style Hoppe-chan designs. A smartphone two-shot photo session with a preferred Mel Petit member is also planned. The event, titled Sun Hoseki “Hoppe-chan” × Mel Petit Original Hoppe-chan Fresh Squeeze Workshop, will take place from 11:00 to 16:00 on Saturday, May 30, 2026, at Village Vanguard Shibuya Main Store.

Scheduled members include Kokomin, Alice, Kotoko, Yuzu, Niko, Kocchan, Reina, Mana, Ruka, Kanon, Ayuna, and Kokona.
