How Long Does It Take to Learn Kanji?
It mostly depends on how many new kanji you add per day. As simple arithmetic, the 2,136 jōyō kanji take about 7 months of new cards at 10 a day, about 14 months at 5 a day, and about 2 years at 3 a day. Reviews continue after that, and reading comfortably also takes vocabulary, so treat these numbers as the minimum time for the kanji themselves.
First, what does learning a kanji mean?
Before any timeline makes sense, you need to decide what counts as learned. There are roughly three levels, and each takes more time than the one before:
- Recognize it: you see the kanji and know its core meaning.
- Read it in words: you can read the common words it appears in, with the right reading for each.
- Write it: you can produce it from memory with correct stroke order.
Most adult learners aim for the second level for every kanji and the third level for the more common ones. The numbers below assume you are adding kanji at that level, learning each through a word or two.
The pace math
There is no trustworthy study that says everyone needs a certain number of months. What you can calculate exactly is how long it takes to see every kanji for the first time at a given daily pace. That is days of new cards only, without counting missed days.
| New kanji per day | 100 kanji (around N5) | 1,000 kanji | 2,136 kanji (jōyō) |
|---|---|---|---|
| 3 | 34 days | 334 days (about 11 months) | 712 days (about 23 months) |
| 5 | 20 days | 200 days (about 6.5 months) | 428 days (about 14 months) |
| 10 | 10 days | 100 days (about 3.3 months) | 214 days (about 7 months) |
| 20 | 5 days | 50 days (about 7 weeks) | 107 days (about 3.5 months) |
The N5 column uses the commonly cited estimate of about 100 kanji, since the JLPT does not publish official kanji lists. Our guide to how many kanji there are explains where the different targets come from.
Reviews are the hidden cost
The table only shows new kanji. Every kanji you add will come back for review several times over the following weeks and months, and that is where most of your daily study time goes. With spaced repetition, intervals grow as you keep remembering a card, so each kanji needs less attention over time, but reviews from many earlier days overlap on any given day.
In practice this means your daily workload grows during the first weeks, then levels off as long as your pace stays the same. If you add 20 kanji a day, your review load will be much heavier than at 5 a day, and a few missed days can leave a pile of overdue cards. Our guide to spaced repetition for Japanese explains how to keep that pile under control.
Pick a pace you can keep on your busiest day, not your most motivated day. Steady 5 a day beats 20 a day for two weeks followed by a break.
Signs your pace is wrong
The right number of new kanji per day is personal, and it can change over time. Instead of trusting a fixed target, watch for these signals and adjust every couple of weeks:
- Too fast: your daily reviews keep growing and take longer than you planned, you get more of them wrong, or you start skipping days because the queue feels overwhelming.
- Too fast: you can recognize new kanji on cards but not in real words or sentences, which suggests you are adding characters faster than you are learning their vocabulary.
- Too slow: reviews are finished in a few minutes, almost every answer is right, and you feel like you are not making progress.
If you are going too fast, the fix is simple: pause new cards for a few days and let reviews catch up. Nothing is lost, and the timeline only moves by those few days. If you are going too slow, raise your daily number by one or two and check again after another two weeks.
How Japanese students do it
For comparison, Japanese schools spread the work across nine years. Children learn the 1,026 kyōiku kanji over six years of elementary school, and the remaining 1,110 jōyō kanji in grades 7 to 9. That is a slow pace, but they also learn to write every character by hand and already know most of the spoken words those kanji represent.
Adult learners can move faster because they can focus on reading first and choose an efficient order. The trade-off is vocabulary: a native child already knows the word でんしゃ (train) before learning to write 電車, while you are often learning the word and the kanji at the same time.
Realistic timelines by goal
- First 100 kanji (around N5): a few weeks at 5 a day. The JLPT N5 kanji list is a good set to start with, and our N5 study plan spreads it over ten weeks for a gentler pace.
- About 1,000 kanji: roughly 3 months to a year of new cards, depending on pace. This is enough for many everyday texts with some lookups.
- All 2,136 jōyō kanji: roughly 7 months to 2 years of new cards for most learners, at 3 to 10 a day.
- Reading native material comfortably: longer than the kanji alone, because you also need the vocabulary and grammar. Kanji are one part of reading, not all of it.
How to go faster without burning out
- Learn the building blocks. Most kanji share a limited set of parts, so learning radicals makes later characters quicker.
- Learn kanji through words. One common word per kanji gives you the reading in context and builds vocabulary at the same time.
- Recall, do not reread. Testing yourself is slower per card but much faster overall. See how to remember kanji for more techniques.
- Use small gaps in your day. Glancing at a kanji on your phone while waiting in line adds exposure without adding a study session.
- Do reviews before new cards. If you are short on time, skip new kanji for the day, not reviews.
Moji is designed around that kind of steady pace, with spaced repetition reviews, kanji widgets on your Lock Screen and progress tracked across JLPT N5 to N1.
Frequently asked questions
- Can I learn all the jōyō kanji in a year?
- Yes, if you add about 6 new kanji every day: 2,136 divided by 365 is about 5.9. You will still have reviews to do afterward, and it only works if you keep the pace on most days.
- How many kanji should I learn per day?
- Many learners find 3 to 10 new kanji a day sustainable. Start low, watch how your daily reviews grow over a few weeks, and only raise the number if reviews stay manageable.
- How long does it take to learn the N5 kanji?
- N5 is commonly estimated at about 100 kanji, so at 5 a day you would see them all in about 20 days, plus a few more weeks of review to make them solid.
- Do I need to finish learning kanji before reading Japanese?
- No. Beginner materials and many manga print furigana, the small kana readings above kanji. You can start reading early and let real text reinforce the kanji you are learning.
Make kanji part of your day
Moji shows a kanji on your Lock Screen every time you check your phone, then brings it back for review right before you would forget it.
