Learn Japanese that actually sticks
A spaced-repetition flashcard app for Japanese: JLPT vocabulary, kanji breakdowns, AI-generated example sentences and a streak that keeps you coming back.
Free — no ads, no in-app purchases, no asterisk.
A review takes seconds
Flip the card, grade yourself, done — and the grade sets the schedule: easy answers push a card days into the future, hard ones bring it back sooner. That's spaced repetition — you review less and remember more.

Japanese flashcard questions, answered
The essentials about learning Japanese with Oboeru.
- How does spaced repetition help me learn Japanese?
- Spaced repetition brings a flashcard back shortly before you are likely to forget it. Oboeru uses the FSRS scheduler and your Again, Hard, Good or Easy rating to adapt every future review, so you spend more time on difficult words and less on words you already know.
- Does Oboeru include vocabulary for every JLPT level?
- Yes. The built-in library includes ready-to-study Japanese vocabulary collections for JLPT N5, N4, N3, N2 and N1, along with hiragana, katakana, radicals and everyday topics.
- Can I create or import my own Japanese flashcards?
- Yes. Add individual words, import an existing Anki deck, or describe a topic and let Oboeru generate a complete collection with Japanese readings and translations.
- What information is included on a flashcard?
- Cards can include kanji, kana, romaji, translations, native pronunciation, example sentences and background notes. Kanji cards also show radical breakdowns, meanings, stroke counts and On and Kun readings.
- Is Oboeru free?
- Yes. Oboeru is free to use in your browser, with no ads and no in-app purchases. Your progress stays with your account across phones, tablets and computers.
