BODY: For a generation of Japanese kids—and plenty of nostalgic adults—the beep of a hungry Tamagotchi is pure childhood. Now that digital pet is landing at the lunch counter: MOS Burger is teaming up with Bandai's iconic virtual pet for a special run of kids'-meal prizes.
Starting July 15, MOS Food Service will offer Tamagotchi-themed extras with its children's "MOS Wai Wai Set" at MOS Burger locations nationwide (a handful of stores excepted). The set starts at ¥560, and the collaboration toys are available for a limited time only, while supplies last.
The lineup leans into Tamagotchi's most beloved character, Mametchi. Kids can score a Mametchi ballpoint pen for everyday cuteness, or a sheet of "kirakira" glitter stickers to plaster on notebooks and school gear. As is standard with MOS Wai Wai Set prizes, exact availability varies by store and stock, so the early days after launch are your best bet.
The timing is no accident. July 15 falls right at the start of Japan's summer school break, when families flood into casual restaurants and kids' meals become a battleground for the cutest bonus. MOS Burger, Japan's homegrown premium burger chain, regularly courts this crowd with character tie-ins—but Tamagotchi, celebrating decades of relevance and a recent revival wave, is an especially sharp draw.
The insider take
MOS Burger occupies a peculiar spot in Japan's fast-food landscape: pricier and slower than McDonald's, but fiercely loved for its "made-to-order" quality and slightly grown-up image. That makes a Tamagotchi tie-up smart cross-generational marketing—the parents paying the bill are the same kids who kept Tamagotchi alive in the late '90s. Expect these prizes to vanish fast in Tokyo's family-dense suburbs, where resale-minded collectors and genuine nostalgia both apply pressure. If you want the Mametchi pen, don't wait for August.
