Chugai Mining Co., Ltd.’s Contents Division has announced a collaboration between “miComet” (Sakura Miko and Hoshimachi Suisei) of hololive and JOYSOUND, running from Saturday, June 13, 2026. New original merchandise, including life-size acrylic stands, will be sold at Karaoke Shop JOYSOUND-affiliated stores nationwide.

Overview of the “miComet × Karaoke Shop JOYSOUND” Collaboration

The collaboration uses new visuals of Sakura Miko and Hoshimachi Suisei, including matching “varsity jacket” outfits and casual after-school “jersey” looks. The campaign runs from Saturday, June 13 through Thursday, July 30, 2026 at 60 affiliated stores nationwide, led by Karaoke Shop JOYSOUND (merchandise is handled at only 20 stores).

Sakura Miko has also been expanding her corporate collaborations, including a study-guide collaboration with Gakken. This time, the lineup—featuring life-size acrylic stands, mini tambourines, and more—is designed to make karaoke more fun.

Original Merchandise

From Saturday, June 13, items on sale include the life-size acrylic stand, varsity jacket ver. (2 types, 2,200 yen tax incl.), trading can badges (550 yen each, tax incl.), trading acrylic stands (880 yen each, tax incl.), an acrylic art board (3,850 yen tax incl.), and a mini tambourine (1,650 yen tax incl.).

From Tuesday, July 7, a second wave of items using the after-school-look new visuals will roll out sequentially, including the life-size acrylic stand, jersey ver. (2 types, 2,200 yen tax incl.).

Collaboration Menu and Collaboration Rooms

Collaboration menu items will also be offered in stores, with one random bonus coaster (8 types) given per item ordered. The bonuses switch content between the first half from Saturday, June 13 and the second half from Tuesday, July 7.

In addition, some stores will host collaboration rooms. Details such as the menu items and the stores hosting collaboration rooms can be found on the special event website.

Prize Campaign and What’s Next

Purchasing 2,000 yen or more (tax incl.) of collaboration merchandise in stores earns one entry postcard, with a “newly recorded voice alarm clock” awarded to 100 people by lottery. In addition, for every 2,000 yen (tax incl.) spent per transaction, customers receive one random bonus postcard (8 types).

Online sales will be available through “Chugaionline,” the EC site of Chugai Mining’s Contents Division. The reservation period runs from 12:00 on Saturday, June 13, 2026 to 23:59 on Friday, July 31, 2026, with shipping scheduled sequentially from September–October 2026 onward.

Impressions and Outlook

Pairing a popular hololive unit with a karaoke chain is a natural fit, since fans’ experience routes overlap easily, and the design entices visitors to enjoy the store visit itself—not just buying merchandise but also through the collaboration rooms and menu. Switching the newly drawn visuals between the first and second halves also appears aimed at encouraging multiple visits during the period. As a strong example of a collaboration connecting VTubers and physical stores, it will be worth watching whether similar efforts continue to grow.
