JLPT Decode - Japanese Vocab

Learn Japanese vocabulary for every JLPT level, N5 to N1, with flashcards that work without internet.

■ A complete word list, level by level

7,928 words organized by JLPT level (N5-N1), with 9,100 example sentences and translations. Meanings are shown in your language - English, Vietnamese, Chinese, Japanese, or Korean.

■ Review exactly when you are about to forget

JLPT Decode schedules reviews with a forgetting-curve algorithm (FSRS). Words come back right before they slip away, so today's studying still holds up on exam day. Two simple buttons - "I know it" or "Not yet" - and the app handles the rest.

■ No dictionary needed

Tap any word for its kanji breakdown, readings, detailed meanings, and example sentences - all inside the app. 2,011 kanji with readings and related words are included, plus handwriting practice.

■ Native audio for everything

17,028 native audio clips are bundled in the app. Every word and example sentence plays instantly, even in airplane mode.

■ Four kinds of quizzes

Meaning choice, kanji reading, fill-in-the-blank, and matching. Wrong answers are collected automatically so you can retry what you missed.

■ Track your progress

A study calendar, level-by-level progress, and accuracy stats show exactly how far you have come.
