Mantra株式会社は、「エンターテインメントから「言語の壁」をなくすこと」に挑戦しているグローバルAIスタートアップです。世界中の誰もが、最新のマンガやアニメ、ゲームを同時に楽しみ、国や文化を超えて語り合う。作品への愛やファン同士の交流から生まれる「異文化への敬意」が、やがて世界の相互理解を育む―。そんな平和で笑顔に満ちた未来を描きながら、私たちはAI技術の研究、マンガ翻訳、そして語学学習サービスの開発に取り組んでいます。 具体的には、マンガ・エンターテイメントに特化したAI技術の研究開発を通じて、高速なマンガ翻訳を実現する翻訳ツール『Mantra Engine』、マンガを用いた英語多読学習アプリ『Langaku』などのサービスを提供しています。また、これらの成果により、HONGO AI Award (2019) 、週刊東洋経済『すごいベンチャー100』(2020)、AAMT長尾賞 (2021)、JEITAベンチャー賞 Early edge賞(2022)、『Google Play ベスト オブ 2025 自己成長部門 大賞(Langaku)』等を受賞しています。 Mantra Inc. is a global AI startup dedicated to “breaking down language barriers through entertainment.” We envision a future where people around the world can enjoy the latest manga, anime, and games together, and engage in conversations that transcend national and cultural boundaries. We believe that the “respect for other cultures” born from a love for these works and interactions among fans will eventually foster mutual understanding across the globe. With this vision of a peaceful, smile-filled future in mind, we are committed to researching AI technology, translating manga, and developing language learning services. Specifically, through R&D in AI technology specialized for manga and entertainment, we provide services such as “Mantra Engine,” a translation tool that enables high-speed manga translation, and “Langaku,” an English extensive reading app that uses manga. Furthermore, these achievements have earned us numerous awards, including the HONGO AI Award (2019), Weekly Toyo Keizai’s “100 Amazing Ventures” (2020), the AAMT Nagao Award (2021), the JEITA Venture Award Early Edge Prize (2022), and the “Google Play Best of 2025 Grand Prize in the Self-Improvement Category (Langaku).”
