YazaGaku
Kyoto · Est. 2014
YazaGaku blends an adaptive AI tutor with weekly 1-on-1 coaching from native Japanese instructors, taking serious adult learners to real, professional fluency — at half the cost of in-person academies.
YazaGaku was founded in Kyoto in 2014 by Dr. Aiko Tanaka, a former Hitotsubashi University lecturer. Today a 62-person team — including 38 native Japanese instructors and 14 curriculum engineers — teaches 187,000+ active subscribers across 94 countries.
Born from a university lecture hall and refined across ten years of in-classroom teaching before it ever shipped as software. Our curriculum is written in Kyoto, by people who live and breathe the language every day.
From Toyota and Nintendo staff to East Asian Studies departments at 47 U.S. universities, our learners are serious adults — professionals, graduate students, and career-changers who refuse to settle for Duolingo streaks.
Over 14 million lessons completed on the platform. Featured in Forbes “EdTech Rising Stars 2022,” TechCrunch Disrupt Kyoto finalist, and G2's Leader quadrant for Language Learning, Spring 2024.
Self-study apps give you infinite content and zero accountability. Conversation tutors give you a chat partner and no structure. YazaGaku fuses both: an AI engine that diagnoses your gaps daily, and a native instructor who meets you on video every week to push you past them.
Our adaptive engine was trained on 1.2 million minutes of native-speaker conversation and is retuned every quarter by the Kyoto linguistics team. It maps your grammar gaps, kanji blind spots, and listening speed — then prescribes the next thirty minutes of practice, every day.
Every paid tier includes weekly 1-on-1 video sessions with a native Japanese instructor — not a $400/month add-on. They review your AI report, correct your pitch accent, and role-play the situations you actually need: o-miai, work emails, salary negotiation.
Our learners reach conversational B1 in an average of 5.2 months — verified through independent TOEIC J-Test benchmarking in 2023. Across 4,200+ JLPT test-takers coached since 2018, our aggregate pass rate is 87.3% — versus the 35.4% national average.
“The AI tells me what to drill before our Tuesday call. The instructor tells me why it matters. That's the difference between a textbook and a teacher.”
100% of our coaching staff is native Japanese — no outsourcing to bilingual non-natives. Every instructor holds a teaching certification and is matched to you by learning style, not availability.
