Is 20 kanji a day too many?

For most people, yes, unless you have a lot of daily time. Every new kanji adds reviews, and twenty a day builds a review pile quickly. Try five for two weeks and raise it only if the reviews feel easy.

How long does it take to learn all 2131 kanji?

At 5 a day without breaks it is about 427 days, at 10 a day about 214. Real life has gaps, so plan for longer, and for review time on top.

What if I miss a few days?

Do the reviews that are due, then pause new kanji until the pile is back to normal. Skipping reviews is worse than skipping new kanji.

How Many Kanji Per Day Should You Learn?

Short answer: three to ten new kanji a day suits most beginners. Five is a good default. The right number is the one where your daily reviews still take about as long as your new lessons. If reviews start to feel heavy, learn fewer new kanji until they ease.

Why the number is smaller than you think

The mistake is to count only the new kanji. Each new kanji comes back for review: the next day, a few days later, a week later and so on. A day where you learn 20 kanji is not one day of work. It is one day plus a share of the next several weeks.

So the question to ask is not “how fast can I learn?” but “how many reviews can I do every day for months?” If the answer is 15 minutes, your pace has to match.

The arithmetic

Here is how long a set takes at a steady rate, with no days off. These are straight divisions, not predictions.

Target	Kanji	At 3 a day	At 5 a day	At 10 a day
JLPT N5 (Kanji Guide)	81	27 days	17 days	9 days
N5 + N4	250	84 days	50 days	25 days
Through N3	620	207 days	124 days	62 days
Through N2	1000	334 days	200 days	100 days
All of Kanji Guide	2131	711 days	427 days	214 days

Those counts are Kanji Guide’s own grouping of its 2131 kanji. Other lists differ, and the JLPT has not published an official kanji list since 2010, so treat the numbers as ballpark. See how many kanji are in each JLPT level.

The table has no sick days, holidays or boring weeks. Add a margin. A plan that takes 14 months on paper often takes 18, and that is fine.

Three starting points

Light: 3 new a day. For people with 10 minutes, or who are fitting kanji around a job or study. You will finish N5 in under a month.

Steady: 5 new a day. The default. Around 15 to 20 minutes with reviews, once you are a few weeks in.

Fast: 10 new a day. For people with an hour or more, a deadline such as a JLPT date, or a strong earlier foundation. It works, but expect the review count to peak after a few weeks.

Start at the steady pace for two weeks. If reviews take less than your learning time, go up by two. If reviews take longer, go down.

Watch the review pile, not the new count

A simple rule: if your review pile is more than you can clear in one session, stop adding new kanji. Do reviews until the pile is back to normal. This keeps the schedule honest.

The app can help. In Kanji Guide you set the number of new kanji per day, and the daily plan shows what is due. Anki has a daily limit for new cards. Other tools handle it their own way. In all of them, new items are the input and reviews are the cost.

What about “kanji in 30 days” plans?

You will see plans that promise a large number of kanji in a month. Some people do it, often with a lot of time and a method like Remembering the Kanji where you learn only meaning and shape first. The trade-off is that you learn to recognise and recall the form, not the readings, so you still need vocabulary afterwards.

If a plan like that suits you, fine. For most people, a slower pace you keep up is better than a fast pace you abandon in week three.

When to go faster

Reasons to raise the pace:

Reviews are finishing quickly and you get most right.
You have a JLPT date and a clear list to cover.
You have already learned kanji in another language, for example Chinese.

Reasons to slow down:

You get a lot of reviews wrong.
You skipped days last week.
You find you are guessing, not recalling.

A sample week at five a day

Monday to Friday: reviews first, then five new kanji, for example 日, 月, 火, 水, 木.
Saturday: reviews only.
Sunday: off.

That is 25 new kanji a week. In a month you have about 100, which covers all of N5 and a good start on N4.

If you come back after a break

Everyone misses days. When you return:

Do the reviews that are due, even if there are many. Split them into two or three short sessions if the pile is large.
Add no new kanji until the pile is back to a normal size.
Expect to get more wrong than usual. That is the schedule doing its job, bringing back the ones you were about to forget.

A short break costs you a few days. A long break costs you a week or two. Neither costs you everything you learned.

Do not skip stroke order or readings

A small point on time. Reading the story is one minute. Watching the stroke order is another. Looking at one or two example words is another. If you rush the new kanji to get the count up, you will pay for it in reviews.

Try it

Open the study app, choose your level, and set a number you can keep for a month. There is an iPhone app too, and the browser version works on Android. For a first-week plan with specific kanji, see how to learn kanji from zero.
