How many kanji do you need to know?
Everyone has heard the scary number: tens of thousands of kanji. The useful reality is far lower, and far more reachable. The real question isn't "how many exist" but "how many it takes to read".
"How many kanji exist" and "how many you need to read" are two unrelated questions. The first is scary, the second has a reassuring answer.
The official figure: 2136
Japan's Ministry of Education maintains a reference list, the 常用漢字 (じょうようかんじ, "regular-use kanji"): 2136 characters since the 2010 revision. It's the set taught through the end of high school, the one you meet in newspapers, laws and government paperwork. Master them and you're functionally literate in Japanese.
Of those, 1026 are the 教育漢字 (きょういくかんじ), learned in elementary school (since 2020). That's the foundation every Japanese child knows before middle school.
How many to actually read
Frequency works in your favor: a handful of kanji come up constantly, the rest are rare. Every kanji learned past the first thousand pays off less and less.
- 1000 kanji
- Cover roughly 95% of the kanji in everyday text.
- 2000 kanji
- Cover roughly 99.7%. Beyond that, you're into rare cases.
- 3000 kanji
- Roughly 99.97%. The gain becomes negligible.
What about the JLPT?
The JLPT (the official Japanese proficiency test) no longer publishes a kanji list since its 2010 overhaul. The figures below are commonly accepted estimates, derived from analyzing past exams, not official lists.
- N5
- ~100 kanji
- N4
- ~300 kanji
- N3
- ~650 kanji
- N2
- ~1000 kanji
- N1
- ~2000 kanji and up
Where to start
Don't aim for 2136 at once. Learn the most frequent kanji first, in the order you meet them while reading. One kanji a day is about 1000 in three years: already 95% coverage, most of the road.
