Mos Burger's operator announced on November 4, 2026, that the chain will sell a limited-quantity 2027 lucky bag featuring Haikyu!! at its stores across Japan, excluding some locations. Online preorders open November 25 at 3 p.m. Japan time, according to a PR TIMES release.
Each ¥5,000 lucky bag contains four collaboration goods and ¥5,000 in meal vouchers, issued as 10 ¥500 tickets. The bag itself has exclusive, newly drawn art. The goods are a square quilted pouch, a matte multi bowl, a set of three zipper bags and a wooden spoon. They feature characters from Karasuno High, Nekoma High and Fukurodani Academy, with one zipper bag for each school. The release describes the designs as easy for adults to use every day. This is the chain's second Haikyu!! collaboration, following last year's Summer Lucky Bag.
Preorders are online only, via Mos Burger's special site, and close December 24, with a limit of five bags per person. Pickup runs from December 30, 2026, to January 11, 2027. Sales end when stock runs out, and some stores may also sell bags over the counter depending on inventory. The vouchers are valid from December 30, 2026, to March 31, 2027. They are not accepted at some special locations, such as dome, theme park and university stores, or for online orders, delivery, full self-checkout registers or table ordering.
The chain will also sell limited quantities of its meat buns packed in a Haikyu!! cooler bag for ¥780. Each frozen, takeout-only pack has two buns. Web preorders run from December 17, 2026, at 3 p.m. to January 11, 2027, with pickup from January 15 to January 31, 2027. The buns will not be sold at special locations, food court stores or stores without online ordering.
Six Haikyu!! extras will be offered with eligible meals, including the children's Mos Waiwai Set (¥560 to ¥680) and a low-allergen menu set with a drink (¥610). Customers choose one extra, which is not sold separately, and stock varies by store. The first wave starts November 11 with a scoreboard-style chalkboard, a Nekoma ballpoint pen and a mini drawstring pouch styled after Hinata's shoe case. The second starts November 25 with a Fukurodani ballpoint pen, a seven-character die-cut sticker set and a set of seven memo clips. Both are scheduled to run until early February 2027 while supplies last. Prices in the release include tax.
From November 11 to November 30, Shoyo Hinata will also appear in Mos Sound Selection, the audio program played at Mos Burger stores nationwide, excluding some locations. In newly recorded messages, Hinata, voiced by Ayumu Murase (村瀬歩), will introduce the lucky bag and speak to customers as they eat.
