Speak Japanese hands-free, with an AI partner who never judges
Japan Cat is an AI Japanese conversation partner built for the time you already have: the drive, the commute, the walk home. You talk, it answers in natural Japanese, corrects you gently, and explains in English, Cantonese or Mandarin — all by voice.
The Japan Cat app: Alano asks you a question in Japanese, you answer, it corrects your grammar and asks a follow-up

What is Japan Cat?
A speaking-first Japanese app — no tapping through exercises.
Japan Cat is a speaking-first Japanese learning app. Instead of tapping through exercises, you hold a real spoken conversation with an AI partner. It listens, replies in Japanese at your level, points out mistakes and more natural phrasing, and keeps the conversation going — so the hours you spend in the car or on the train turn into speaking practice.

Who it is for
You can read a little. You freeze when you speak.
Japan Cat is for learners who can read a little Japanese but freeze when they have to speak — and for anyone who wants daily practice without booking a tutor.
Levels run from Beginner (JLPT N5–N4) to Intermediate (N3) and Advanced (N2–N1).
Hong Kong · Taiwan
It is especially popular with learners in Hong Kong and Taiwan, because explanations can come in Cantonese or Mandarin, written in Traditional Chinese.
