How to Learn Kanji for the JLPT: A Complete Guide

Quick answer: Learn kanji through the words they appear in, review them with spaced repetition, and break each one into smaller parts you already know. You need roughly 80–100 kanji for N5, about 300 for N4, 650 for N3, 1,000 for N2 and 2,000 or more for N1. These are community estimates, since there's no official JLPT kanji list. The JLPT never asks you to write kanji by hand, so focus on recognizing them and knowing how they're read in real words.

Kanji are the part of Japanese that worries learners most, and also the part where a good method makes the biggest difference. This guide covers what kanji are, how many you need for each level, how readings and radicals work, the study methods that actually stick, and how the test checks your kanji. If you're still choosing a level, start with the complete JLPT guide.

What are kanji, and why does Japanese use them?

Kanji are characters that came to Japan from China, starting well over a thousand years ago. Each kanji carries a meaning, and most have one or more pronunciations. 山 means "mountain," 水 means "water," and 食 has to do with eating.

Modern Japanese mixes three scripts:

• Hiragana for grammar: particles, verb endings and words with no common kanji.
• Katakana for foreign loanwords and emphasis, like コーヒー (coffee).
• Kanji for the core meaning of most nouns, verb stems and adjective stems.

Here's how they work together in one sentence:

私は毎朝コーヒーを飲みます。
Watashi wa maiasa kōhī o nomimasu. I drink coffee every morning.

The kanji (私, 毎朝, 飲) carry the meaning, the katakana spells the loanword, and the hiragana (は, を, みます) handles the grammar.

Why not just write everything in kana? Japanese has a small set of sounds, so it has many words that sound the same. こうえん can mean a park (公園) or a lecture (講演), and きかん can mean a period (期間) or an organization (機関). Kanji make these clear at a glance. They also show where one word ends and the next begins, since Japanese doesn't put spaces between words. Once you can read kanji, Japanese text actually becomes faster to read, not slower.

Japan's official list of kanji for everyday use, the jōyō kanji, has 2,136 characters. That's the practical ceiling for most learners, and N1 covers a large share of it.

How many kanji do you need for each JLPT level?

Level	Kanji (approx.)	What that looks like
N5	80–100	Numbers, days of the week, basic people, places and verbs
N4	300	Everyday words for family, school, shopping, travel and weather
N3	650	Notices, simple articles, common words in daily life
N2	1,000	Newspapers, work emails, general nonfiction
N1	2,000+	Most kanji in everyday adult writing, including abstract words

The JLPT doesn't publish official kanji lists. These numbers are community estimates, so textbooks, apps and websites all give slightly different figures. Treat them as targets, not hard rules.

The totals are cumulative. N3 includes the N5 and N4 kanji, and so on. For the full breakdown of what each level expects beyond kanji, see JLPT levels explained. If you're just starting, our JLPT N5 kanji list gives you all 79 kanji in the Kantan JLPT N5 set, with meanings and readings.

How do kanji readings work?

Most kanji have two kinds of reading:

• On'yomi (音読み): the "Chinese" reading, based on how the character was pronounced when it came to Japan. It's mostly used in compound words made of two or more kanji, like 学生 (gakusei, student).
• Kun'yomi (訓読み): the native Japanese reading. It's mostly used when a kanji stands alone or is followed by hiragana, like 学ぶ (manabu, to learn).

Some kanji have several readings of each type, and some have only one. There are also exceptions, like 今日 (kyō, today), where a whole word has a special reading that doesn't come from its individual kanji.

This is the area that confuses most learners, so we've written a full explanation with examples: on'yomi vs kun'yomi. The short version is that you shouldn't memorize every reading of a kanji in isolation. Learn readings through words, and the patterns follow.

What are radicals, and do you need them?

Most kanji are built from smaller, repeating parts called components. One of these parts is the kanji's radical, the part that dictionaries use to organize characters. Radicals often hint at the meaning:

• 氵 (water) appears in 海 (sea), 池 (pond) and 泳 (swim).
• 亻 (person) appears in 休 (rest), 体 (body) and 何 (what).
• 言 (speech) appears in 話 (talk), 語 (language) and 読 (read).

You don't need to memorize all 214 traditional radicals. But knowing the 20 or 30 most common ones turns a new kanji from a random tangle of lines into a few familiar pieces. That makes kanji much easier to remember and to tell apart. Our guide to kanji radicals covers the most useful ones, with examples.

What are the basic rules of stroke order?

Every kanji has a standard stroke order. Even if you never write by hand, knowing the basics helps you see a kanji's structure, count strokes for dictionary lookup, and use handwriting input on your phone, which often works better when you write in the right order.

The main rules:

1. Top to bottom: 三 is written top line first.
2. Left to right: in 川, the left stroke comes first.
3. Horizontal before vertical when they cross: in 十, the horizontal line comes first.
4. Left-falling stroke before right-falling stroke: in 人 and 八, the left stroke comes first.
5. Center before the sides for small symmetrical shapes: in 小 and 水, the middle stroke comes first.
6. Outside before inside, but close the box last: in 国, write the left side and the top-right corner of the frame, then the inside, then the bottom line.
7. A vertical stroke that cuts through everything comes last: in 中, the long vertical line is the final stroke.

There are exceptions, but these rules get most kanji right. Learn them once and they'll carry you through thousands of characters.

What is the best way to learn kanji?

There's no single best method, but the learners who make steady progress combine a few habits.

Use spaced repetition

Spaced repetition shows you each kanji or word just before you're likely to forget it. Items you know well come back rarely, and items you miss come back soon. This is the most efficient way to move hundreds or thousands of items into long-term memory, and it's why flashcard apps that schedule reviews work so well for kanji.

Two tips: keep your daily reviews short and consistent, and add new items at a pace you can sustain. Ten new items a day for six months beats fifty a day for two weeks followed by burnout.

Learn kanji through vocabulary

A kanji on its own is abstract. A word is something you can use. Instead of drilling 生 with all its readings, learn words like 学生 (gakusei, student), 先生 (sensei, teacher) and 生まれる (umareru, to be born). You learn the kanji's meaning, its readings in context, and useful vocabulary at the same time.

This also matches how the JLPT tests kanji. You're always asked about kanji inside words, never about a lone character's readings.

Use mnemonics for tricky kanji

A mnemonic is a short story or image that links a kanji's parts to its meaning. Many kanji lend themselves to this:

• 休 (rest) = a person (亻) leaning against a tree (木).
• 明 (bright) = the sun (日) plus the moon (月).
• 男 (man) = a rice field (田) plus power (力), someone working in the fields.
• 森 (forest) = three trees (木).

Not every kanji has a neat story, and you don't need one for every character. Save mnemonics for the kanji you keep missing.

Read real Japanese

Flashcards build recognition. Reading builds speed and shows you how kanji behave in real sentences. Start with graded readers or simple texts at your level, and read a little every day. The JLPT reading section is timed, so quick kanji recognition matters.

Should you practice writing kanji by hand?

It depends on your goals. The JLPT is entirely multiple choice, so handwriting isn't tested. Many learners find that writing a kanji a few times helps them notice its details, especially for look-alike pairs. But writing every kanji many times is slow, and that time is often better spent on vocabulary and reading.

A good middle ground: learn the stroke order rules, write new kanji once or twice to understand their structure, and write more only for kanji you keep confusing. If you plan to live or work in Japan, you'll want more handwriting practice later.

How does the JLPT test kanji?

Kanji show up throughout the test, but two question types in the language knowledge section focus on them directly:

• Kanji reading: a word written in kanji is underlined in a sentence, and you choose the correct reading in hiragana. These questions test details like long vowels (こう vs こ), small っ, and voicing (か vs が).
• Orthography: a word is written in hiragana, and you choose the correct kanji spelling. The wrong choices often use look-alike kanji or kanji with the same reading. This question type appears at the lower and middle levels.

Kanji also matter in every other section. In reading, you have to understand passages quickly. In vocabulary questions, you need to know what kanji words mean. Even in listening, knowing kanji helps you understand the words you hear.

For a breakdown of every section and question type, read the JLPT test format guide, and check the official JLPT website for the current format before your test.

A kanji study plan for each JLPT level

These plans assume you study most days and review with spaced repetition. Adjust the pace to your schedule.

N5 (about 80–100 kanji)

Learn hiragana and katakana first. Then add three to five kanji a day, focusing on numbers, days of the week, time words, and basic verbs like 見る, 食べる and 行く. You can cover the N5 kanji in about a month. Spend the rest of your time on vocabulary and grammar.

N4 (about 300 total)

Add about 200 new kanji at five a day, which takes six to eight weeks. This is a good stage to learn the most common radicals, because the kanji start to get more complex. Learn two or three words per kanji.

N3 (about 650 total)

You need around 350 new kanji. At five to eight a day, that's two to three months. Start reading short texts like news for learners or simple manga. Pay attention to kanji that look alike, such as 待 (wait) and 持 (hold).

N2 (about 1,000 total)

Another 350 or so kanji, but the words get more abstract and you'll see many two-kanji compounds. Focus on compound vocabulary rather than single kanji. Read every day, because N2 reading passages are long and timed.

N1 (2,000+ total)

The jump is big: roughly 1,000 new kanji. Expect to spend six months or more on kanji alone. Learn kanji in vocabulary, read widely (newspapers, essays, novels), and review consistently. At this level, reading volume matters as much as flashcards.

For a full plan that fits kanji alongside vocabulary, grammar and practice tests, see our JLPT study plan. Grammar deserves its own time too, so check the Japanese grammar guide for what to study at each level.

Common kanji mistakes to avoid

• Memorizing every reading of a kanji up front. Many kanji have readings you'll rarely see. Learn the readings that appear in common words, and pick up the rest as you meet them.
• Learning kanji without words. Knowing that 生 means "life" doesn't help you read 先生. Always pair kanji with vocabulary.
• Ignoring look-alikes. Kanji like 人 and 入, 土 and 士, or 末 and 未 are easy to mix up. When you notice a pair, study them side by side.
• Skipping reviews. New kanji are easy to add and easy to forget. Clear your reviews before adding new items.
• Only recognizing kanji in flashcards. If you can only read a kanji on its card, you don't quite know it yet. Reading in context is the real test.
• Spending all your time on handwriting. Unless writing is a personal goal, use that time for reading and vocabulary instead.

Frequently asked questions

How long does it take to learn 2,000 kanji?

At 10 new kanji a day with steady reviews, you could cover 2,000 in under a year, but very few people sustain that pace. For most learners studying alongside vocabulary and grammar, two to four years to comfortably read around 2,000 kanji is more realistic.

Should I learn kanji or vocabulary first?

Learn them together. Study vocabulary words, and learn the kanji that appear in them. This gives you meanings, readings and useful words all at once.

Do I need to know stroke order for the JLPT?

No. The JLPT doesn't test stroke order or handwriting. Still, the basic rules help you understand kanji structure and use handwriting input or dictionaries, so they're worth learning once.

Does knowing Chinese help with kanji?

Yes, a lot. Chinese speakers already know most meanings and many shapes, though some characters are simplified differently, and Japanese readings must still be learned from scratch. Many Chinese speakers find N2 and N1 kanji much faster than other learners do.
