The male vocal group Monaki appeared Monday at a FamilyMart event to promote the new "Ajiwau Gohobi Fruit" frappe [1].

This collaboration blends celebrity influence with retail product launches to attract consumers to the convenience store's seasonal beverage line.

The event, held on June 22, 2026 [2], featured the group's four members: Jin, Kenken, Oyone, and Sakai Jr. [1]. The gathering served as both a formal announcement and a tasting session for the new product [1].

During the promotion, the group engaged in entertainment segments, including a "kime-gao" or determined-face challenge [1]. The event was marked by comedic interactions between members. Jin attempted to joke by pretending to be Kenken after being mistaken for him [3].

Oyone asked, "What should I do?" [4]. The interaction highlighted the group's dynamic during the public appearance.

Kenken commented on the unpredictability of the performance. "I was nervous. I wondered if I was doing something strange," Kenken said [5].

The promotion aimed to generate social media engagement and foot traffic for FamilyMart locations through the group's fan base [1].

"What should I do?"

The use of entertainment groups like Monaki for product launches reflects a common Japanese marketing strategy that leverages 'idol' culture to create viral moments. By incorporating comedic challenges and interpersonal chemistry into a corporate press event, the brand transforms a standard product announcement into a piece of entertainment content designed for digital sharing.
