Haikyu!! and Rilakkuma are coming together for a new collaboration featuring pop-up stores, exclusive merchandise, and a collaboration lottery.

Both anime series are produced by Production I.G, which created 12 original illustrations for the collaboration. The artwork brings together characters from Karasuno High, Aoba Johsai High, Nekoma High, Fukurodani Academy, and Inarizaki High with Rilakkuma, Korilakkuma, and their friends.

Pop-up stores will be held in Tokyo and Osaka from November 20 through December 6, followed by Sapporo, Kyoto, and Hiroshima from December 18 through January 17, 2027. The first merchandise lineup includes collectible badges, acrylic stands, pouches, socks, and more.

Cookies featuring cards with the collaboration artwork will also be released in January 2027, with preorders beginning September 24. A collaboration lottery featuring additional items is scheduled to launch on January 23, 2027.
