At IACS you practice Japanese, where what is left unsaid carries as much as what is spoken, in real conversation with an AI tutor who is awake whenever you are. You set the pace; the tutor keeps it natural, corrects you gently, and remembers what you have learned. Your vocabulary and grammar are tracked from one lesson to the next, so every conversation builds on the last.

How it works
Pick a tutor, start a conversation in Japanese, and talk about whatever you like. The tutor meets you at your level, weaves in new words, and corrects you without breaking the flow. The words you learn are saved and quietly revisited until they stick. No schedule, no pressure, no clock.
