Study Japanese vocabulary in English from your own notes and slides
Upload a PDF, slide deck, set of notes or a photo of a vocabulary page. Get Japanese-English flashcards you can review with spaced repetition.
Why build Japanese-English decks from your own lessons
Most Japanese courses hand you vocabulary lists, kana charts and lesson slides, and the words only stick once you drill them in both directions. Ready-made printable sheets are easy to find, but they rarely match your textbook or your teacher's word list. DeckOwl turns your own material into Japanese-English flashcards with spaced repetition, so the words you miss come back sooner.
- Cards pull directly from your lesson files, so the vocabulary matches what you will be tested on.
- Spaced repetition schedules reviews around the cards you find hardest.
- Edit any card before studying if a reading or translation needs correcting.
- Export to Anki or CSV is available on the Plus plan for studying on other devices.
Works from your own material
Upload PDFs, DOCX or PPTX files, plain notes, or photos of a vocabulary page and get cards built from the words your course actually uses.
Spaced repetition built in
Words you miss come back sooner, and words you know fade to longer gaps, so review time goes to the vocabulary that needs it.
Study in the browser
The free plan includes 3 generations per month and browser study, so you can try your first deck before paying anything.
How it works
Upload your vocabulary
Add a lesson PDF, slides, a text file of word pairs, or a photo of a page. No credit card is needed to start.
Generate the flashcards
DeckOwl creates cards with the Japanese term on one side and the English meaning on the other, which you can check and edit.
Review on a schedule
Study in short sessions and let spaced repetition decide which cards come back next, starting with the ones you missed.
Put the Japanese on the front for recognition practice and the English on the front for recall, and try both. Keep kana and kanji in separate decks if your course tests them separately, since reading a character and remembering its meaning are different skills.

Frequently asked questions
How many Japanese-English flashcards should I make for a weekly quiz?
Start with the words from one lesson, about 20 to 40 cards, so you can review them daily before the quiz. If a deck grows too large, split it by unit or separate kana and kanji into their own decks.
Should I study kana and kanji in the same deck as vocabulary?
Separate decks work better while you are learning to read, because recognizing a character and recalling its meaning are different tasks. Combine them once you are comfortable with both.
Can DeckOwl export my Japanese flashcards to Anki?
Yes, Anki export is included in the Plus plan at $39/year or $7.99/month, which also includes unlimited generations. The free plan lets you study in the browser but does not include exports.
Can I upload a photo of a vocabulary page?
Yes, photos are read with text recognition, but check the Japanese characters on each card before studying, since handwriting and small print can be misread.
