How Many Kanji Are There? What Learners Really Need

How many kanji are there? More than you will ever need. Large dictionaries list tens of thousands of characters, but most of them are rare or old. Everyday Japanese runs on the 2,136 jōyō kanji, the official list of characters for general use, last revised in 2010. That is the number that matters for learners.

How many kanji are in Japanese?

There is no single count. Kanji came from Chinese, and the biggest dictionaries collect tens of thousands of characters, including old variants and rare name characters that almost nobody uses. That is why you will see very large numbers quoted online.

Real life is much smaller. The jōyō kanji list (常用漢字, jōyō kanji, kanji for common use) is set by the Japanese government. Newspapers and official documents mostly stay within it. When they need a rarer character, they often write the word in hiragana instead or add its reading in small hiragana. Since 2020, Japanese children learn 1,026 of these kanji in primary school and most of the rest at secondary school.

How many kanji do you need for JLPT N5?

Not many. The JLPT has not published official kanji lists since the test changed in 2010, so every number you see is an estimate. Many study guides suggest roughly 100 kanji for N5 and roughly 300 by N4, and some lists give fewer. Treat these as a rough guide, not a target to tick off.

N5 kanji are simple, common characters such as 日 (day, sun), 人 (person), 山 (mountain) and 水 (water), plus numbers and days of the week. Our guide to the JLPT levels from N5 to N1 explains what each level tests.

How many kanji do you need to be fluent?

Fluency is about words and listening as much as reading, so there is no exact kanji number. For reading, the jōyō list is a good long-term goal, because it covers most of what adults read every day. You do not need all of it to hold a conversation, read simple texts or enjoy a manga with reading help.

It also helps to know that one kanji can be read in more than one way. 日 is read nichi in 毎日 (mainichi, every day), but bi at the end of 日曜日 (nichiyōbi, Sunday), and 今日 (kyō, today) has a reading of its own. This is why counting kanji tells you less than counting the words you can read.

What is the best way to learn kanji?

Start with hiragana and katakana. They write every sound in Japanese, and beginner materials use them to show how kanji are read. Our guide to hiragana vs katakana explains which to learn first.

Then learn kanji inside words, not on their own. 日本 (Nihon, Japan) and 日本人 (Nihonjin, Japanese person) teach you 日, 本 and 人 together with a reading you will actually use. A list of single characters with every possible reading is hard to remember and hard to use.

• Learn a few new kanji a day, through words you want to know.
• Say each word out loud, so the reading sticks with the shape.
• Review often. Kanji fade quickly if you do not see them again.
