JLPT N1 — the summit of Japanese proficiency.
N1 is the highest level of the JLPT. It certifies that you can read complex and abstract writing — editorials, criticism, literature — and understand spoken Japanese in any setting, including nuance and implication.
What JLPT N1 covers
Around 2,000 kanji and 10,000 vocabulary words — full reading proficiency for any text.
- Around 2,000 kanji cumulatively — the full set behind native literacy.
- Around 10,000 vocabulary words including literary, technical, and idiomatic terms.
- Grammar: advanced and archaic constructions, subtle register, and implied meaning.
Who JLPT N1 is for
For serious, advanced learners pursuing native-level reading, translation work, or graduate study in Japanese. N1 rewards consistency above all.
How InitialJ helps you pass
Spaced repetition (SRS)
Every kanji and word has its own review schedule. Difficult items return sooner; mastered ones step aside — so the volume stays manageable.
Belt-based progress
Nine SRS stages, shown as karate belts from white to burned, give a clear sense of how solid each item really is.
Bilingual meanings
Meanings come in English and French, and reviews accept answers in either language — French speakers are first-class here.
Dictionary & grammar
Browse every kanji and word with furigana, romaji, examples, and mnemonics, plus grammar exercises tuned to each level.
Where our lists come from
Our N1 kanji and vocabulary lists are compiled from public JLPT specifications and frequency data, then reviewed manually and aligned with the in-app SRS decks. Counts are approximate ranges; the official JLPT does not publish a fixed word list.
