Yokoso: Learn Japanese

Free forever. No ads, no streaks, no paywalls. Yokoso adapts around what you already know and teaches Japanese for daily life: shop signs, prices, counters, menus, useful phrases, vocabulary, and grammar in context.

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 are 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 has a memory hook grounded in mnemonic research, and you can rewrite hooks in your own words to make them personal.

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, and college-course equivalence, with field notes on why progress feels the way it does.

BRING YOUR HISTORY Imports WaniKani progress and recent Bunpro grammar too. Paste a token and your known kanji stay known, re-synced daily; recent 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 for everyone finding their feet in Japan.
