Yokoso: Learn Japanese

Free forever. No ads, no streaks, no paywalls. Yokoso reads your level without a placement test and teaches the Japanese on real signs, menus, and price tags.

Just moved to Japan? Yokoso is the fastest way to make the Japanese around you stop looking incomprehensible and it's free forever. No ads, no streaks, no locked features.

YOUR LEVEL, WITHOUT A TEST No placement quiz. Yokoso probes as you learn: what you already know gets skipped, what you half-know gets confirmed, and coming in with prior Japanese never costs you a minute.

THE JAPANESE AROUND YOU Shop doors (営業中), station signs, menus, price tags, and the phrases that run daily errands. Numbers drilled the way registers actually say them, irregular readings included.

MEMORY THAT STICKS A spaced-repetition engine tuned to a measured retention target adapts to every answer. Each kanji ships with a memory hook grounded in mnemonic research and you can rewrite hooks in your own words, which is exactly what the research says works best.

MISTAKES THAT TEACH Yokoso tracks which wrong answer you chose. Confuse ください with お願いします and the difference becomes its own lesson, re-tested side by side. And if the app marked you wrong on a typo, one tap says "I was actually right" your judgment outranks the software.

GRAMMAR YOU DISCOVER When you've been using a pattern correctly, Yokoso names it then proves you can transfer it to a sentence you've never seen.

HONEST PROGRESS JLPT tracking as facts, not cheerleading — coverage vs. readiness, N5 and up. Milestones on real scales: ILR, CEFR, college-course equivalence, with field notes on why progress feels the way it does.

BRING YOUR HISTORY The only app that imports WaniKani progress and Bunpro grammar too. Paste a token and your known kanji stay known, re-synced daily; grammar you've studied gets confirmed instead of re-taught.

YOURS, EVERYWHERE, PRIVATELY Works fully offline. Cross-device sync with no account required. No analytics, no tracking, no third parties.

Everything above is free, permanently. Optional supporter contributions exist for people who want development to continue — they unlock nothing, because nothing is locked.

Built in Aomori, for everyone who just landed.
