日本語を学ぶ
A free Japanese learning platform. Learn and drill kana, kanji, vocabulary and every verb form, then put it to use in conversation — all in one place. No account, nothing to install.
Type rōmaji — it becomes kana as you go, exactly as it does in the drill.
A recorded exchange. The real thing answers live, stays in character, and speaks out loud.
Most people learning Japanese end up with a dictionary in one tab, a kanji app on their phone, a conjugation chart screenshotted from somewhere, and a textbook they've stopped opening. This is all of it in one place — and it's free because there's nothing here to sell you.
Rather than describe it — this is real content from the site, exactly as it appears on the page.
Ten interconnected tools covering the foundations of Japanese
Can't read a word of Japanese yet? Good — start at the top.Nothing here needs prior knowledge, nothing keeps score unless you ask it to, and every tool is free with no account.
Practice all 104 hiragana and katakana characters. Learn both Japanese writing systems side-by-side with audio pronunciation, clear charts for basic kana, dakuten (voiced sounds), and combination characters. Click any character to hear how it sounds.
Kana on a conveyor-belt sushi bar. Type the reading before the plate passes your seat—or flip it and pick the kana from tiles. Choose a course from Apprentice to Master, race the clock in Rush hour, and see every kana you’ve eaten or missed on the Menu, where one tap orders it back down the express lane.
Clear, visual explanations of how Japanese verb conjugation actually works. Understand the why behind the patterns, not just the rules. Learn to identify verb types, understand the hiragana sound system, and see step-by-step walkthroughs of each conjugation type.
Comprehensive quick-reference conjugation charts covering 16 verb forms for all three verb types: Godan (五段), Ichidan (一段), and Suru (する). From basic forms (negative, polite, past) to advanced (passive, causative, conditional), color-coded tables show you exactly how each form is created. Perfect for quick lookups or comparing patterns side-by-side.
Browse all 129 verbs in our database, organized by type (Godan, Ichidan, Suru) with kanji, hiragana, and English meanings. Search to find specific verbs instantly, or filter by JLPT level (N5, N4, N3) to focus on vocabulary appropriate for your level.
The heart of Katsuyō Academy. Practice conjugating verbs across 16 forms with instant feedback. No Japanese keyboard needed—type ikanai and it becomes いかない as you go, and kanji answers count just as much as kana. Choose a difficulty or a single form, filter by JLPT level, and work in rounds that end with a summary. Verbs you get wrong come back until you've got them twice, and every mistake is explained with the exact rule you needed.
Actually use what you've learned. Pick a scenario—ordering food, a doctor's visit, buying cinema tickets—or describe your own. Prefer something looser? Free chat, or drill one grammar form until it sticks. Set the level to N5, N4 or N3 and read the Japanese in kanji, kana or rōmaji. Stop whenever you like for a written assessment: what went well, what to fix, the full transcript, and the words you met along the way.
Graded short stories from N5 to N1. Read in kana, with furigana, or kanji only, listen along, then answer comprehension questions graded instantly.
Practice 941 essential Japanese words with intelligent flashcards. Study with hiragana, kanji, and katakana across 8 different learning modes. Toggle between Japanese→English or English→Japanese practice, show or hide readings, and see both scripts side-by-side. Smart shuffle prioritises unseen cards, and progress tracking shows how many you've studied.
Practice 2,300 kanji from the acclaimed Kodansha Learner's Course. Each card shows the kanji character, English keyword, on'yomi and kun'yomi readings, plus example vocabulary with meanings. Filter by level, shuffle cards, or jump to any KLC number. Keyboard shortcuts included!
Katsuyō means conjugation. It is the thing that stops most learners, and it is where four of these tools point at the same problem from different sides.
Twelve verb forms and the adjectives, each with the rule for every verb class, worked examples, and the exceptions spelled out rather than left for you to trip over. The reference you come back to.
You are given a verb and a target form; you produce it. Sixteen forms, five verb types, hints in three escalating steps, and a report at the end of exactly which forms keep catching you.
Every conjugation drill goes one direction. This one goes the other: you are shown 食べさせられた and you work out where it came from — which is what reading actually asks of you.
When you meet a form you don't recognise in real Japanese, paste it in. 食べさせられなかった walks back to 食べる, naming every layer it removes on the way.
The tools aren't separate apps that happen to share a nav bar. They pass you between them.
New to Japanese? This is the order that works. About an hour a day gets you through it.
I built Katsuyō Academy because I needed it myself. Scattered textbook chapters, confusing online resources, flashcard apps that didn't quite work the way I wanted — I wanted everything in one place, designed the way I learn best. This is that place. If it helps you too, then it's done its job.
