Moomin: Moominvalley Summer Festival launches Nov 12, 2026 — Switch physical pre-orders open Aug 21

The Switch package editions include a shared set of physical bonuses: a Moominvalley postcard book featuring the title’s art, an embroidered handkerchief, a mesh pouch, a frosted-glass–style keychain, and a glossy “churun” clear sticker. Shochiku Games says those items appear in both the limited edition and the regular retail edition, though the regular edition’s bonus set is available only in the first production run. Images and item details will be posted on the game’s official site on a rolling schedule.

Retailer-specific preorder bonuses have also been locked in. The announcement lists Rakuten Books, amiami, Amazon, Joshin, animate, Bic Camera, Sofmap, and Kojima as participating stores preparing original store-only extras. Shochiku Games did not include the exact item images in the initial release; the company plans to publish visuals and fuller item descriptions on the official product pages.

Shochiku Games published a new trailer on its official YouTube channel that includes the first public gameplay scenes. The footage mixes recreated moments from Tove Jansson’s novels with newly designed sequences created for the game, showing exploration and story beats in the theatre setting. The trailer is positioned as the first extended look at the game’s scenes and atmosphere.

The game’s story follows the Moomintroll family after a great flood. While waiting for the absent Snufkin to return from his travels, the Moomins drift to an odd building: a theatre stocked with costumes, scripts, and what the announcement calls the unique “magic” of the stage. Players will encounter both lovingly reconstructed scenes from the original novels and brand-new adventures written for the title, presented in the point-and-click format developed by Crossbridge.

Shochiku Games is handling the package distribution for both Nintendo Switch and Nintendo Switch 2; pre-orders are available now at physical stores and e-commerce sites across Japan. The publisher encourages reservations by listing participating shops and promising that the official site will update with product images and store-bonus visuals. For collectors who prefer physical extras, the combination of a limited edition, first-run regular bonuses, and retailer-specific items makes pre-order timing relevant.
