Mantra Corporation Makes Major Move into Game Localization Industry

Mantra Corporation, based in Bunkyo, Tokyo, has announced an exciting new chapter in its journey by officially entering the game localization sector starting in 2026. Known for its translation work in the realm of manga and other entertainment works, Mantra aims to expand its services by incorporating the latest AI technologies alongside skilled native translators.

The company's first significant foray into gaming localization comes with the translation of Yunyun Denpa Syndrome, a rhythm adventure game developed by Alliance Arts, which will support a total of 15 languages, including 10 languages that Mantra will handle. This innovative game merges attributes of music games with bizarre narrative elements, ensuring immersive gameplay experiences. By dedicating about three months to translate approximately 120,000 words, Mantra successfully delivered the localization in French, Italian, German, Spanish (Spain), Spanish (Latin America), Russian, Portuguese (Brazil), Polish, Turkish, and Thai. This ambitious endeavor also showcased their commitment to addressing text additions and modifications during the development phase.

Upon reaching the August 31, 2026 deadline, the results were impressive: the game garnered 1,202 user reviews on Steam, with an astounding 96.2% of them being positive. Notably, feedback from Polish and Thai users proved exceptionally favorable, reflecting the quality and accuracy of Mantra's translation efforts. Furthermore, Yunyun Denpa Syndrome ranked within the top 100 sellers on Steam across several countries, including France, Italy, Spain, Russia, Poland, and Thailand—a clear testament to the game’s popularity and the successful localization.

Alliance Arts commented on their collaboration with Mantra for this project, expressing appreciation for the quick responses and adept handling of user feedback. They noted that the leap into this expansive multi-language deployment was a significant endeavor, yet the results proved successful thanks to a productive partnership with Mantra. Users have praised the game in reviews, reflecting a positive community sentiment towards the translation work conducted by Mantra.

By integrating AI into the translation and quality management process, alongside leveraging the expertise of native translators, Mantra aims to extend the benefits of their workflow to game developments.

Future Prospects
