How Many Vocabulary Words Do You Need for Each JLPT Level?

You need roughly 800 vocabulary words for JLPT N5, 1,500 for N4, 3,700 for N3, 6,000 for N2, and 10,000 for N1. Like the kanji counts, these are estimates — the JLPT replaced official word lists with can-do descriptions in 2010 — but they are consistent across major study resources and reliable for planning. This guide gives the numbers, explains what "knowing" a word means in a multiple-choice exam, and lays out the review system that makes these volumes achievable.

The counts at every level

Each level includes everything below it, so the real number you learn between levels is the gap: ~700 more words for N4, ~2,200 more for N3, ~2,300 more for N2, and ~4,000 more for N1. Those gaps explain why the jump from N4 to N3 feels like a wall for most learners — it is the biggest relative jump in the whole exam.

Why there are no official lists

Before 2010 the JLPT published exact word and kanji lists per level. The revised exam replaced them with can-do descriptions, so today's "JLPT vocabulary lists" are reconstructions from past papers and frequency data. Treat any list as an excellent approximation: if you know the ~800 most frequent words, an N5 passage will not surprise you, even if one word on the paper was not on your list. Frequency-ordered decks are the most honest version of this — they are built from actual exam and corpus data.

What "knowing" a word means on the JLPT

The JLPT is entirely multiple choice, so you never produce vocabulary — you recognize it. For this exam, knowing a word means:

1. Recognizing it instantly in a sentence, without translating.
2. Knowing its reading — the language-knowledge section constantly tests kanji-to-hiragana readings.
3. Knowing how it combines — most exam vocabulary is two-kanji compounds, and the exam loves testing the difference between near-synonyms in context.

You do not need to spell it, use it in your own writing, or produce it in speech. Recognition speed is what scores points, and recognition is exactly what spaced repetition trains.

The review method that makes the numbers possible

Learn words in sentences, not as isolated items. A card that reads 大きい → "big" is forgettable; a card that reads この荷物は大きいです (このにもつはおおきいです, "this luggage is big") gives the word context, a grammatical slot, and a real memory hook.

Let a spaced-repetition system (SRS) schedule your review. A thousand-word deck reviewed by hand is a chore; the same deck reviewed by an SRS at expanding intervals is a habit that fits in 10 minutes a day. Our JLPT vocabulary SRS strategy covers the setup in detail — new cards daily, review before new, and a suspension rule for words you have answered correctly too many times to matter.

Meet words in text. Vocabulary learned in a deck but never met in a sentence stays fragile. Read at your level (reading practice by level) so review decks and reading feed each other — a word that appears in both is essentially learned.

Learn kanji inside the words. Every JLPT word is written with kanji on the exam, and reading questions require recognizing compounds fast. Studying vocabulary while learning the kanji it uses doubles the value of every card. See the kanji counts by level to plan both together.

A realistic pace

At 20 new words a day with SRS review, N5's ~800 words take about six weeks; the N4 gap (~700 more) about five; the N3 gap (~2,200 more) about fifteen; the N2 gap (~2,300 more) about seventeen; and the N1 gap (~4,000 more) about thirty weeks. The daily count matters less than never skipping review — the SRS only works if the queue is never allowed to rot. Fit vocabulary alongside grammar, kanji, and listening with a structured plan like our N5 study plan, and check your readiness under exam timing with a full-length mock before you sit the real thing.

FAQ

How many vocabulary words do I need for JLPT N3? About 3,700, including all N4 and N5 words. There is no official list; this is the consistent estimate across major study resources.

Is there an official JLPT vocabulary list? No. The JLPT stopped publishing word and kanji lists in 2010 and replaced them with can-do descriptions. Every list you find is a reconstruction from past papers and frequency data.

Do I need to write JLPT vocabulary by hand? No. Every question is multiple choice. You need to recognize words, select correct readings, and understand meanings in context — never produce them.

How many words should I learn per day for the JLPT? Twenty new words a day is a sustainable target for most learners. The daily count matters far less than never skipping your spaced-repetition review.
