GudaGuda Studio has released a free Steam demo for Yokai Mart ahead of its Steam Next Fest appearance from 19 to 26 October 2026. The full game is planned for Q1 2027.
Yokai Mart has opened its doors on Steam with a free demo. It introduces Aoi's unusual night shift at a convenience store in a Tokyo suburb. GudaGuda Studio released the playable preview before the game's appearance at Steam Next Fest, which runs from 19 to 26 October 2026. The full release is still planned for Q1 2027.
Steam's own event information confirms the October dates. Next Fest is scheduled to run from 19 to 26 October 2026. The recurring showcase gives Yokai Mart a public window to reach players before its planned full release.
A shop with a secret
The story begins with a familiar family duty. Aoi helps her grandmother run the local convenience store. After dark, the business changes when otherworldly visitors start to appear. The store is more than a place for stock management and customer service. It is where Aoi meets spirits from Japanese folklore and starts building relationships with them.
Yokai Mart is a single-player, story-driven convenience store simulation. Its main loop combines helping customers with Aoi's personal journey. Her relationships with the spirits help her try to make friends with them. The demo therefore has a purpose beyond running a shop. The store is also where the story and social systems unfold.
The game currently has five identified Yokai. The source material does not give their individual abilities or explain how each relationship develops. The demo will need to show how much interaction sits behind that feature instead of leaving the spirits as simple atmosphere.
What the demo confirms
The release is available on Steam now. Players can download the demo in English, German, Japanese or Simplified Chinese. It runs on Windows, macOS and Linux. The demo also works on Steam Deck, giving the project a route to desktop players and Valve's handheld PC audience.
Steam's community announcements include a "Yokai Mart Playtest" entry with the changelog note "Order and Choices swapped." That entry shows that an active playable build was present in Steam's ecosystem by 21 to 22 September 2026, before the stated 25 September demo release date. Playable testing was visible before the public demo date rather than appearing only when the announcement went live.
Those platform details matter because Yokai Mart is a small independent release, not a large multi-platform launch. GudaGuda Studio is a two-person independent game studio based in Switzerland. Yokai Mart is the studio's first commercial release. The available information confirms the demo's operating systems and language support, but it does not give system requirements, performance targets, save-transfer details or accessibility features.
The main dates are close together. The demo was released on 25 September 2026. Steam Next Fest runs from 19 to 26 October 2026. The full game is planned for Q1 2027. That quarter is a release window, not an exact launch date. No price or edition information has been announced in the supplied material.
SteamDB offers a separate sign of the project's arrival in Steam's backend. Its records show unknown Steam app IDs linked to development activity. One was first seen on 16 September 2026 and another on 18 September 2026. These records do not confirm the game's final content or release date. They do place its Steam-side activity in the middle of September.
For comparison, another recent demo release also used October's Next Fest to put a small simulation in front of players before launch. Yokai Mart takes a different path. It ties shop work to character relationships and Japanese folklore instead of focusing only on incremental progression.
Steam Next Fest test
Steam Next Fest gives the demo a clear public window. The event does not change the game's development status. Yokai Mart remains an upcoming title with a full release planned for the first quarter of 2027. The demo can show how the opening systems work. It cannot establish the final story, the full scope of the customer relationships or the stability of the finished version.
A playable build was already visible through Steam's community and backend records by late September. This makes the release more than a future announcement. Players can already access the game in demo or playtest form. The Next Fest appearance is a later promotional and discovery opportunity, not the first chance to try it.
That matters for a story-led simulation. A short preview can show the shop's basic rhythm and introduce the tone of its supernatural encounters. The full experience will depend on how those systems develop. The supplied announcement does not state the demo's length, the number of store activities, the structure of Aoi's progression or whether the five Yokai make up the entire cast.
No independent performance testing accompanies the release information. Compatibility with Windows, macOS, Linux and Steam Deck confirms where the demo is meant to run. It does not show how consistently it performs on different hardware. Players should treat the platform list as availability information, not as a technical guarantee for frame rate, resolution or battery life.
A focused first release
GudaGuda Studio's size gives Yokai Mart a clear identity before launch. A two-person Swiss team is handling development and publishing for its first commercial game. The project supports four languages and three desktop operating systems, along with Steam Deck compatibility. These are confirmed production choices. They do not prove that every feature will arrive with the same level of polish in the final build.
The studio has also said that it did not use generative AI during development. That is a stated production position, not a gameplay feature. It is relevant context for a first commercial release built around an authored setting, its characters and folklore-inspired encounters.
Players now have the most useful early information available for Yokai Mart: a playable sample rather than a description alone. The demo's value will depend on whether the convenience-store routine and spirit relationships work together as one story system. GudaGuda Studio has made a clear first move by offering access before Next Fest. The Q1 2027 launch is still when the project's full scope will have to be judged.
Steam demos provide limited evidence by design. They can show the feel of a game's opening loop and reveal practical compatibility issues. They do not prove the final content volume, performance or launch polish unless those points are tested separately. For Yokai Mart, the free build offers a direct look at its shop-and-yokai premise while the broad release window leaves the finished game's scale unconfirmed.
