Most guides put JLPT N4 at roughly 300 to 1,000 study hours from zero, with most landing between 550 and 1,000. The range is wide because it depends on your starting point, your kanji background and how well you study. Use it to plan, then confirm readiness with mock tests.
Most guides put JLPT N4 at roughly 300 to 1,000 study hours from zero, with most landing between 550 and 1,000. The range is wide because it depends on your starting point, your kanji background and how well you study. Use it to plan, then confirm readiness with mock tests. If you are weighing whether to aim for N4, the first question is how long it will take. Here is what the estimates say, what changes them, and how to turn hours into a calendar. How many hours does JLPT N4 take? There is no official number, so every figure is an estimate from a school, a study site or a community. Here is how a few of them compare: Coto Academy: about 550 hours for learners who already know kanji, and about 800 to 1,000 hours for those who do not. Japonin: about 600 to 1,000 hours. Nihongo Master: about 300 hours, reached in around five months at roughly 15 hours a week. That is a spread of 300 to 1,000 hours. Part of the difference comes from what each source counts. Some count hours from zero, while others count the extra hours after N5. When you read an estimate, check which one it is. What do you need to know for N4? N4 builds on N5 with more vocabulary, more grammar and more kanji. According to a common list, you need about 300 kanji and about 1,500 vocabulary words. Our own look at community lists found cumulative counts of about 245 to 284 kanji for N4, so treat 250 to 300 as a working range, not an exact target. If you are not yet at N5, start with that first. Our JLPT levels explained guide shows what each level expects. What changes your study time? Four things move the number up or down: Kanji background. Learners who already know kanji, such as many Chinese speakers, need fewer hours. Coto Academy's own numbers show a gap of 250 or more hours between the two groups. Where you start. If you have already passed N5, you only need the extra hours for N4. Study quality. An hour of focused practice with feedback counts for more than an hour of passive listening. Consistency. Studying a little every day beats long, occasional sessions, because you forget less between sessions. How do I turn hours into a schedule? Divide your target hours by the hours you study per day, then by 30 to get months. Here are the results for two common targets: Study per day 550 hours 1,000 hours 1 hour about 18 months about 33 months 2 hours about 9 months about 17 months 3 hours about 6 months about 11 months If you are starting from N5, your total will be shorter. If you use the 300-hour estimate, one hour a day takes about 10 months and two hours takes about 5. These are planning numbers, not promises. Your own mock test scores are the real measure of readiness. Can I pass N4 in six months? It is possible if you already have N5-level Japanese and study about two to three hours a day. At one hour a day, six months is unlikely. Be honest about how many hours you can protect each week, since pushing for a faster timeline often leads to burnout. Is Genki enough for N4? Genki 2 covers most N4 grammar, but learners report gaps in vocabulary, kanji and listening. We looked at this in Is Genki enough for JLPT N5 and N4? Plan on extra hours for vocabulary, kanji and exam-style listening on top of the textbook. How does this fit the US test schedule? In the US, the JLPT is offered once a year, in December. That makes planning backwards from the test date more important. Count your realistic weekly hours, estimate your total, and make sure the end date falls before December with a month to spare for mock tests. Our guide to the JLPT in the USA covers registration and test sites. If you are still working toward N5 first, our N5 study plan for working adults shows how to build a weekly routine, and you can adapt it for N4. How do I know if I am ready?

Frequently asked questions
- How many hours does it take to pass JLPT N4?
- Estimates run from about 300 to 1,000 hours from zero. Several guides land between 550 and 1,000. Your background and study quality can move the number a lot.
- How long does it take to go from N5 to N4?
- One estimate puts it at about five months at roughly 15 hours a week, which is about 300 hours. Others are higher, so plan on a range and check your progress with mock tests.
- How many kanji do I need for N4?
- Common lists suggest about 250 to 300 kanji cumulative, along with about 1,500 vocabulary words. There is no official list, so counts differ by source.
- Can I skip N5 and go straight to N4?
- Yes. You can register for any level without passing the lower ones. You still need the N5 knowledge, so plan the hours for both levels.
- Does knowing Chinese or Japanese kanji help?
- Yes. Learners who already know kanji tend to need fewer hours, since recognizing characters is one of the slowest parts for beginners.
