AI × Japanese Education × Japanese Culture
— Learn Japanese, Deeply.
What textbooks never teach: 'Japanese that fits the situation'. With AI and the expertise of Japanese language education professionals, we turn language and culture into complete teaching materials. For Japanese learners. For Japanese teachers.
Japanese that fits the person and the moment
The same words land differently depending on who you're talking to. Our flagship AI tools read honne, politeness, and cultural context through a sociolinguistic, pragmatic lens. Start free.
Scene-Fit Japanese Maker
What makes Japanese sound just right? Say the same thing your way across relationship × politeness. Phrases that fit any situation—plus the cultural "why" behind them—become your ready-made lesson.

"My Japanese feels off—but why?" Find out. We diagnose your Japanese by relationship × scene, visualize its "fit" on 5 axes, correct your grammar, explain cultural differences, and suggest the phrase that fits the moment perfectly.

"We'll consider it positively"—but what does that really mean? AI decodes the true intentions behind Japanese expressions. Visualize the gap between literal words and real meaning with a tatemae (façade) score, backed by syntactic and pragmatic signals. Get insights into cultural context and recommended responses.

Pragmatics-first
Teach the situational gap, not just grammar. The AI pinpoints the specific speech habits your learners carry over from their native language and builds lessons around the contrast with what sounds natural in Japan.
End-to-end into the lesson
Intake → course design → lesson plans → homework in a single flow. Teacher scripts and student-facing materials are kept separate, so you can screen-share directly in online lessons.
Handouts ready to hand out
Student materials support furigana and native-language translations. Your data stays on your device — no student personal information is stored on our servers.
