BODY: If you've ever wanted to belt out anime tunes in a room decked out with your favorite VTubers, Japan's biggest karaoke chain has you covered this summer. On June 5, 2026, Chugai Mining announced "miComet ร Karaoke Shop JOYSOUND," a collaboration running from June 13 through July 30.
The headliners are no strangers to the spotlight. Sakura Miko and Hoshimachi Suisei โ two of Hololive's most prominent talents โ perform together as the unit "miComet," a pairing whose chemistry has spawned countless clips, fan art, and original songs. Bringing them into physical JOYSOUND locations is a natural fit, given that both streamers are accomplished singers in their own right.
The campaign bundles the usual collab trimmings: a themed food-and-drink menu designed around the duo, plus exclusive merchandise available for purchase at participating shops. While full details on specific items and which locations will host the event are still rolling out, these JOYSOUND tie-ups typically include original-art coasters, drink garnishes, and limited goods that move fast among dedicated fans.
The roughly six-week window โ comfortably spanning summer break โ positions the collab to catch students and working fans alike during karaoke's peak season in Japan.
The insider take
From Tokyo, this reads as a textbook example of how Hololive monetizes fan affection beyond the screen. JOYSOUND collabs have become a reliable ritual for VTuber and anime IP, and miComet specifically carries weight because the pairing is fan-canonized rather than corporate-manufactured โ meaning the emotional buy-in is already there. Expect merch to sell through quickly and resale listings to appear within hours. For Cover Corp, low-overhead, high-affinity partnerships like this are exactly the kind of steady revenue that complements the streaming and concert business.
