Learn Japanese
like a ronin.

The challenge

Japanese looks impossible from the outside: three writing systems, particles, politeness levels. Travellers give up before they land, and JLPT students drown in textbooks. We wanted a way in that feels like play, not homework.

Our answer

Ronin Master is our own mobile app, designed and built in-house and currently in development. Two paths in one: a travel mode with essential phrases in romaji only (no kanji needed), and a JLPT mode that trains you from N5 to N1 in the real exam format. Every answer is corrected instantly and explained.
