JapanLang makes Japanese click.
Work through five grammar levels, each unlocked by passing three progressive tests — Meaning, Sound, and a challenge game that pushes what you've learned under pressure.
FIVE CHALLENGE GAMES
• Rice Game — catch the right translation before it burns
• Japanese Whisper — listen, recall, self-rate your understanding
• Sentence Rain — build sentences as words fall from the sky
• Koi Fish — swap fish into the right order before time runs out
• Samurai Sneak — memorise a scrambled sentence and arrange it from memory
BUILD REAL SENTENCES
GrowJPN is a branching sentence builder. Pick one word at a time — subject, object, verb — and watch grammatically correct Japanese sentences form naturally. The engine blocks nonsense combinations so everything you build is real Japanese.
STUDY YOUR WAY
Swipe through the word bank by category: verbs, nouns, adjectives, time words, family, numbers, and more. Flashcard mode drills any category on demand.
TRACK YOUR PROGRESS
Earn XP and build a daily streak. Every level you unlock is saved — pick up exactly where you left off.
Designed for complete beginners through early intermediate learners. No prior Japanese knowledge needed.
