How Many Hours to Pass Each JLPT Level?

Why the JLPT no longer publishes study hours

The Japanese-Language Proficiency Test is run by the Japan Foundation and Japan Educational Exchanges and Services. When it was redesigned in 2010, the organisers stopped publishing lists of the kanji, vocabulary and grammar each level requires. Their official FAQ gives the reason: “We believe that the ultimate goal of studying Japanese is to use the language to communicate rather than simply memorizing vocabulary, kanji and grammar items.” Instead, each level is defined by what you can do, in the Summary of Linguistic Competence Required for Each Level. N5 is “the ability to understand some basic Japanese”. N1 is “the ability to understand Japanese used in a variety of circumstances”.

That is a reasonable position for a test body, but it leaves learners guessing. Every hour figure you see on study blogs today is either a community estimate or a recycled version of the old official numbers.

The old official numbers

The JLPT's own comparison of the old and new tests still reproduces the pre-2010 criteria, and they were specific:

• Old Level 4: around 100 kanji and 800 words, “normally reached after studying Japanese for around 150 hours and after completion of the first half of an elementary course”
• Old Level 3: around 300 kanji and 1,500 words, around 300 hours, after completion of an elementary course
• Old Level 2: around 1,000 kanji and 6,000 words, around 600 hours, after completion of an intermediate course
• Old Level 1: around 2,000 kanji and 10,000 words, around 900 hours

The New JLPT Guidebook then maps the old levels onto the new ones. N5 is approximately the same as old Level 4, N4 as old Level 3, and N2 as old Level 2. N1 is “approximately the same level as the current Level 1 test, but designed to measure slightly more advanced abilities”. N3 was newly created to bridge old Levels 2 and 3. The FAQ puts it the same way: people who could pass old Levels 1, 2, 3 and 4 can pass N1, N2, N4 and N5.

Carry the hours across and you get the closest thing to an official table that exists:

• N5: about 150 hours
• N4: about 300 hours
• N3: no official figure; it sits between 300 and 600
• N2: about 600 hours
• N1: 900 hours or more, since N1 aims slightly above old Level 1

Why those numbers run low for English speakers

Read the old criteria again and notice the phrasing: “after completion of an elementary course”, “after completion of an intermediate course”. These were hours of structured teaching, the kind of total a Japanese language school would count. Three things push a self-taught English speaker well past them.

Kanji background. Learners who already read Chinese characters start with a large head start on the written side of the test. The most detailed public figures come from the Japan Language Education Center (JLEC), a private Japanese-language school, which published average study hours for its own full-time students in Japan who passed each level between December 2010 and July 2015. Its totals count class time, homework, preparation and personal study (the school's page is offline, but an archived copy survives, and the table is reproduced in Wikipedia's JLPT article). For students without prior kanji knowledge versus those with it:

• N5: 325–600 hours (250–450 with kanji)
• N4: 575–1,000 hours (400–700 with kanji)
• N3: 950–1,700 hours (700–1,100 with kanji)
• N2: 1,600–2,800 hours (1,150–1,800 with kanji)
• N1: 3,000–4,800 hours (1,700–2,600 with kanji)

This is one school's data on its own students, and it does not publish its method or sample size, so treat it as a rough guide rather than a measurement. The direction is still telling: the non-kanji ranges run about 1.3 to 1.9 times higher, and the gap widens at the top.

FSI's measure of Japanese. The U.S. Foreign Service Institute puts Japanese in its hardest group, Category IV, at 88 weeks or 2,200 class hours, for students aiming at a score of 3 on the ILR scale. FSI describes a typical week as 23 hours of class plus 17 of self-study, so the full effort is closer to 88 × 40 = 3,520 hours. ILR 3 and N1 are different scales measuring different things, so this is not a conversion. It does show that 900 hours for advanced Japanese is far below what a government school with excellent teachers budgets for English speakers.

The test is receptive only. The JLPT has no speaking or writing section. It tests language knowledge (vocabulary, kanji, grammar), reading and listening. Hours you spend talking with a tutor are valuable, but they move your JLPT score only indirectly. If your log is half conversation practice, expect the calendar to stretch.

A planning range you can use

Putting this together, here is the range we would plan around as a self-studying English speaker without prior kanji. These are the JLEC ranges for students without kanji knowledge. We use them rather than the old official figures because they count all study time, which is what you will be logging, while the old figures count course hours only. Treat the old official number as a floor, not a target. JLEC's students were also living in Japan, with daily exposure that nobody logs, so if you are studying on your own outside Japan, expect to land in the upper half of each range.

• N5: 325–600 hours (old official figure: about 150)
• N4: 575–1,000 hours (about 300)
• N3: 950–1,700 hours (no official figure)
• N2: 1,600–2,800 hours (about 600)
• N1: 3,000–4,800 hours (900 or more)

If you already read Chinese characters, use the lower “with kanji” ranges above instead.

The ranges widen as you go up, because by N2 the variation between learners (prior languages, how much you read, whether you live in Japan) is larger than any formula can absorb. Your own logged hours will tell you more than any table once you have a few hundred of them.

Turning hours into a test date

The JLPT is held twice a year in Japan, in July and December (the FAQ lists 5 July and 6 December for 2026), and some overseas cities only offer one of the two sittings. So the useful question is not “how long will N4 take” but “which sitting can I be ready for”.

A worked example. Say you start on 1 October 2026 and aim for the December 2027 sitting (assuming it falls, as usual, on the first Sunday of the month, 5 December). That is 430 days, or roughly 61 weeks. At 7 hours a week (an hour a day), you would bank around 430 hours: inside the N5 range above and past the old official N4 figure of 300, but short of the 575 hours at the bottom of the N4 range. If you want N4 on that date, you need closer to 10 hours a week, which gives about 610 hours, just inside the range. Not a sure thing, and worth knowing before you pay the fee.

The same arithmetic for a bigger goal: 1,600 hours, the bottom of the N2 range, at 90 minutes a day is about 1,067 days, or just under three years. Seeing that number early is what stops people from booking N2 six months after finishing their textbook.

What to log, and why the split matters

The JLPT has sectional pass marks as well as an overall one. Every level is scored out of 180, with overall pass marks of 100 for N1, 90 for N2, 95 for N3, 90 for N4 and 80 for N5, according to the official scoring page. You also need a minimum in every scoring section: 19 out of 60 in each of the three sections for N1 to N3, and for N4 and N5, 38 out of 120 in the combined language knowledge and reading section plus 19 out of 60 in listening. A strong overall score with weak listening can still fail.

That makes the split of your hours as important as the total. Log at least four activity types separately: kanji and vocabulary, grammar, reading, and listening. If, after a month, listening is 10% of your time and the test gives it a third of the points at every level, you have found your problem before the exam did. A tracker such as LangTrack logs each session by activity and minutes, so you can see that split without building a spreadsheet.

For section-by-section plans once you have chosen a level, our JLPT N5 preparation guide and JLPT N2 preparation guide go into weekly milestones.

The bottom line

The JLPT's own historical figures (150, 300, 600, 900) are real and worth knowing, but they were written around classroom courses, and they make no distinction between learners who already read Chinese characters and those who don't. If you are an English speaker studying on your own, plan for two to five times as much, pick a sitting, and check your logged total against the range every month. The total will not pass the test for you, but it will tell you early whether the date you picked is realistic.
