Search the Complete Japanese Vocabulary Library
The Word Library lets you search and browse thousands of Japanese vocabulary words by kana, kanji, romaji, or meaning. Every entry shows the word written in kana and kanji, its romaji reading, and its meaning in your language, with audio you can play and verb or adjective conjugations where they apply. Add any word to a study deck and review it later with spaced repetition.
How to Use the Word Library
Type any part of a word — the kana, the kanji, the romaji, or its meaning in your language — into the search box to filter the list instantly. Tap a word to open its detail panel, where you can hear the audio, read its meaning, and see its conjugated forms. Use the add button to save a word to a study deck, then head to the decks page to review your words with spaced repetition.
Build Decks and Study with Spaced Repetition
Searching is only the first step — real vocabulary growth comes from review. Group the words you are learning into decks, then study them on the decks page with a spaced-repetition system that shows each word again just before you are likely to forget it. This schedules your practice efficiently, so you spend time on the words you find hardest and breeze past the ones you already know.
Kana, Kanji, and Romaji Together
Each word is shown three ways: in kana, in kanji where a word uses it, and in romaji. Seeing all three side by side helps you connect a word's sound to its written forms, so you can read it in native Japanese text and still check the romaji when you are unsure. Audio for each word reinforces the correct pronunciation and pitch.
Keep Learning
Pair the library with the rest of the site: organize words into study decks, look up characters in the kanji library, study Japanese grammar, or review the hiragana and katakana chart.
Frequently Asked Questions
How many Japanese words do I need to know?
A few thousand words covers most everyday conversation and reading. Learners often aim for around 2,000 words for basic fluency and 6,000 or more for comfortable reading. This library gives you thousands of words to search, sort into decks, and study at your own pace.
How should I study vocabulary?
Combine recognition with active recall. Search and read words here, add the ones you are learning to a deck, and review them with spaced repetition on the decks page. Studying words alongside example sentences and grammar helps the meanings and readings stick.
What is spaced repetition?
Spaced repetition is a review method that shows you each word again just before you are likely to forget it, stretching the interval each time you remember correctly. It is one of the most efficient ways to move vocabulary into long-term memory without wasting time on words you already know.
Why does each word show kana, kanji, and romaji?
Japanese is written with kana and kanji, while romaji spells the sounds in the Latin alphabet. Showing all three lets you read a word the way it appears in real Japanese text and still confirm the pronunciation from the romaji when you need to.
Can I hear how each word is pronounced?
Yes. Many words include audio you can play from the detail panel, so you can check the pronunciation and practice saying it aloud. Hearing a word as you learn it makes it far easier to recognize and reproduce later.
