Langaku review
A mobile reading-led app for English learners who want manga, vocabulary tools, and quizzes.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Langaku turns licensed Japanese manga into English reading practice, primarily for Japanese-speaking learners. Readers can switch dialogue between English and Japanese by tapping a panel, adjust how much English appears across four levels, and listen to English dialogue and words. A built-in dictionary, contextual AI explanations, vocabulary review, and quizzes connect reading with language study. Progress tracking, zoom mode, and adjustable font style support the reading experience. Its manga-led format suits learners who want to study through stories rather than a standalone lesson sequence.
The free plan gives one manga ticket per day and access to free content. Langaku+ costs ¥2,480 per month and adds four tickets per day, access to all titles and episodes, AI features, a coin-purchase bonus, and an ad-free experience. That makes the subscription chiefly about expanding daily reading and access, while the free option offers a way to try the reading format with a limited daily allowance. The published Japanese pricing is monthly; prices and interface details can vary by country.
The product is distributed on iOS and Android, with a mobile-only deployment. Its combination of bilingual panels, adjustable English exposure, audio, and post-reading vocabulary tools is closely tied to manga reading, rather than broad language-course coverage. Choose Langaku if manga is a motivating way to practice English and you want explanations and review alongside reading. It is a weaker fit for learners seeking a desktop option or a learning path centered on formats other than manga.
