Tamsoft Corporation (株式会社タムソフト) is a Japanese video game developer founded in 1992, best known for their work on the Battle Arena Toshinden, Onechanbara and Senran Kagura series. Its current president, Toshiaki Ōta, previously worked at Toaplan as one of the six original team members and head of software development. They began by being contracted to Takara in the 1990s developing several games for them, their first being the Game Boy port of SNK's Samurai Showdown. This was followed by the popular fighter Battle Arena Toshinden on Sony's PlayStation console, using the 'HyperSolid' graphics engine; Tamsoft would afterwards develop the rest of the main series: Battle Arena Toshinden 2, 3, and 4. They also made SteamGear Mash on Sega Saturn, Penny Racers and the fighting adventure game AbalaBurn on PlayStation. In 1998, Tamsoft released their first self-published game, Guardian's Crusade. They returned to being a contractor and developed several games in D3 Publisher's Simple 1500 series and then Simple 2000 series on PlayStation 2, including the Onechanbara series. More recently they developed the Dream Club dating sims, and the Senran Kagura hack and slashers for Marvelous, and have also co-developed a number of spin-off games in the Hyperdimension Neptunia series.
