Get Your Japanese Corrected — Kindly
Post a short sample of your Japanese — typed or spoken — and get instant feedback from Professor Toshiro, plus corrections from the community. The best advice rises to the top through voting. Posting imperfect Japanese is the entire point.

AI Speed, Human Nuance
Other apps make you wait for a volunteer, or hand you AI feedback with no second opinion. Kaizen Corner gives you both in one ranked thread.
Instant AI feedback
Professor Toshiro replies the moment you post — catching particle, conjugation, word-choice, and politeness issues.
Voice or text
Record up to 30 seconds and get feedback on your actual pronunciation and naturalness — not just a transcript.
Voting you can trust
Every correction — even Toshiro's — is voted on, so the right answer rises and confident-but-wrong advice sinks.
Steady, low-stakes improvement
Kaizen (改善) means continuous improvement. Make a little progress every day.
