Overview
Tasto Alpha Co. Ltd. is a Japanese game development studio that presents itself as a partner for publishers and platform holders seeking original concept work, programming, and full game and app development. Its official site describes the company as adding an 'Alpha Factor' to game development, creating titles 'loved by players the world over.' The studio offers programming services spanning casual apps through PC and console development, with staff trained in Unity and Unreal Engine 5, and it supports clients from project kickoff to completion. It also advertises game and app development experience built on more than 20 casual apps and designers who have worked on titles selling over a million copies. The company's portfolio mixes original concept and development credits with contract work. Among its original titles are Ufouria: The Saga 2 (known in Japan as へべれけ2), a revival of the Sunsoft/Imagineer-linked Ufouria series released for modern platforms including PlayStation, Xbox, and Nintendo Switch; Arcana of Paradise - The Tower - (ハテナの塔 -The Tower of Children-), which appeared in 2022 and won a BitSummit Media Award; Witch of Oblivion, an original concept and development project dated 2024; and Witch and Lilies, an early access title from 2024. The studio also created ONE PIECE Kung Fu Dugong unison march ♪ (ONE PIECE クンフージュゴンのユニゾン大行進♪) for Shueisha's Game Creators CAMP, where it won the One Piece Game Award Grand Prize, though distribution of that title has ended. Tasto Alpha's leadership includes CEO and Lead Programmer Takuma Okubo. According to the company's staff introduction, Okubo joined BottleCube Inc. in 2008, working primarily as a lead programmer on roughly 20 smartphone apps, including MOTTAINAI Relax, Oyasumi Orgel, Nestlé Balance Recipe for Mind and Body for Nestlé Japan, and Tele Bing for Microsoft Japan. He joined AppBankGames Inc. in 2012, worked as a programmer on Dungeons & Golf, and was responsible for development and operations of Cross Horizon. He joined Onion Games in 2015, according to the same profile. The studio operates in the Japanese and international game markets, releasing titles on Steam, Nintendo eShop, PlayStation Store, and Xbox Store. Its business model combines original IP creation with work-for-hire development and programming support, positioning it as a flexible independent studio rather than a large publisher. Because the available evidence is limited to the official website and a Wikidata identifier, some corporate details such as founding year, headquarters address, and ownership structure are not confirmed here.
History
Tasto Alpha Co. Ltd. is a Japanese game development company whose public profile is built around the idea of adding an 'Alpha Factor' to game development. The official website presents the studio as a development partner capable of handling programming and full game and app production, from casual apps to PC and console titles. The company states that its programmers are trained in Unity and Unreal Engine 5 and that it can support development from kickoff to completion. It also cites experience developing over 20 casual apps and designers who have launched titles selling more than a million copies. The studio's own works list shows a mix of original concept and development credits. Ufouria: The Saga 2, known in Japan as へべれけ2, is described as an original concept and development project now on sale across the official site, Steam, PlayStation Store, Xbox Store, and Nintendo eShop. Arcana of Paradise - The Tower - (ハテナの塔 -The Tower of Children-) is likewise listed as original concept and development, dated 2022, and noted as a BitSummit Media Award winner. Witch of Oblivion is listed as an original concept and development project dated 2024, with a Steam page and wishlist call to action. Witch and Lilies is listed as a 2024 development project in early access. The studio also created ONE PIECE Kung Fu Dugong unison march ♪ (ONE PIECE クンフージュゴンのユニゾン大行進♪) for Shueisha Game Creators CAMP, where it won the One Piece Game Award Grand Prize; distribution of that title has ended. The company's staff introduction provides the clearest biographical thread available in the evidence. CEO and Lead Programmer Takuma Okubo joined BottleCube Inc. in 2008, where he primarily served as lead programmer and developed approximately 20 smartphone apps, including MOTTAINAI Relax, Oyasumi Orgel, Nestlé Balance Recipe for Mind and Body for Nestlé Japan, and Tele Bing for Microsoft Japan. In 2012 he joined AppBankGames Inc., working as a programmer on Dungeons & Golf and taking responsibility for the development and operations of Cross Horizon. In 2015 he joined Onion Games, according to the same profile. This career path across mobile, social, and independent console game development informs the studio's stated ability to handle both casual apps and larger PC and console projects. Beyond its own titles, Tasto Alpha markets itself as a service provider. Its programming offer covers casual apps through PC and console development, and its game and app development offer emphasizes fulfilling game systems for any title. The company's public materials do not, in the supplied evidence, specify a founding year, headquarters location, ownership structure, or employee count. The Wikidata entry Q114691825 exists for the entity, but the supplied evidence does not include structured statements from it. As a result, the historical record here is limited to project credits, awards, platform releases, and the CEO's professional background.
