Mantra Inc. officially launches 'Langaku', an app for learning Japanese through Japanese manga, in Korea

Mantra Inc. announced on the 6th that it has officially launched 'Langaku', an app that allows users to learn Japanese by reading Japanese manga in their original text, in Korea. This app is available on iOS and Android.

Langaku is a service officially certified by Shueisha, characterized by combining manga viewing with learning functions. After starting service in Japan in 2022, it surpassed 1 million cumulative downloads, and in June of the same year, the number of works available to read in Japanese and English exceeded 100. However, the Korean version is not a simple translation of the Japanese version, but has been redesigned in terms of functions and work composition to suit Korean users.

In the Korean version, touching a Japanese dialogue in the manga will display the original text and the Korean translation together, and it also provides AI explanations based on context and Japanese voice support. Users can save newly learned expressions in a vocabulary book to review them. The industry believes that this method can lower the barrier to entry compared to existing grammar-centered learning. However, the company added that AI explanations may contain inaccurate information.

Mantra Inc. stated that it confirmed the demand for wanting to learn Japanese by reading Japanese manga in its original text through market research in Korea in 2025. The company plans to continuously refine the translation, explanation, and voice functions based on the reactions of Korean users and actual usage data. The lineup of works is also planned to be expanded step-by-step within the scope of rights licensing.
