JLPT in 30 Days: A Last-Month Study Plan for N5, N4 and N3

The December JLPT is on Sunday, December 6, 2026. If you are reading this in early November, that is about four weeks away, and you probably fall into one of two groups. Either you have been studying steadily and want to stop wasting the last month, or you signed up back in August, life happened, and you are now doing the maths with a slightly cold feeling in your stomach.

Both groups need the same plan, and it starts with an honest sentence: a month is not enough to learn a level, but it is plenty of time to turn what you half-know into points.

Most people who fail a level they were close to do not fail because of one big gap. They fail because of fifteen small ones: a grammar pattern they recognise but mix up under time pressure, kanji they can read slowly but not at test speed, a listening section they never practised in one sitting. Those are exactly the things four weeks can fix.

The short answer: yes, you can prepare for the JLPT in 30 days, if you already have a foundation at your target level. Start with a full practice test to find your weak spots, then spend the weeks on grammar you mix up, reading speed and listening, in that order. Aim for 60 to 90 minutes a day and take three full practice tests before December 6.

What One Month Can and Cannot Do

Let us get the bad news out of the way first.

If you are sitting N4 and you have never really studied plain form, you will not master it by December while also catching up on kanji. If you are sitting N3 and your vocabulary is still around N4 size, a month will not close a gap of a couple of thousand words. Trying to do that usually ends with you skimming everything and retaining nothing.

What a month can do is surprisingly a lot:

• Make you fast at things you already know, which matters because the clock costs people as many points as the questions do.
• Fix the handful of grammar points you keep confusing, which tend to be the same handful the test loves to ask about.
• Build the stamina to listen carefully for the whole listening section without drifting off halfway.
• Stop you losing easy points to the answer sheet, the clock and nerves.

So the rule for this month is simple. No new textbooks. No new apps. No starting over from chapter one. You work with what you have, and you aim every hour at the score.

Know the Number You Are Chasing

The JLPT is pass or fail, and you need two things at once: a minimum total score, and a minimum in each scoring section. Miss either one and you fail, however good the other is.

Two things in that table should change how you spend the month.

First, at N5 and N4, listening is a third of your score. A lot of people treat it as the section they will "pick up naturally". If you scrape the minimum 19 on listening, you need 61 out of 120 at N5 and 71 out of 120 at N4 on everything else. That is a much harder test than the one you thought you were taking.

Second, at N3, reading gets its own sectional minimum. You cannot hide a weak reading score behind strong vocabulary any more. If reading is your slow section, it deserves more of this month than it feels like it does.

One warning about practice tests: the official scores are scaled, so a raw 95 on a mock paper does not mean you would get 95 on the real thing. Use your mock scores to see where you are improving, not as a prediction of your result.

Here is how long each part of the test is, from the official JLPT site:

Listening times can vary slightly with the length of the recordings. The full breakdown, including how scaled scores work, is in our JLPT exam guide.

Start With a Full Practice Test

Before you plan anything, find out where you actually are. Not where you feel you are.

Do one complete practice test, timed, in one sitting, this weekend, at roughly the time of day your real test starts. The best sources are the official ones: the sample questions on jlpt.jp and the official practice workbooks published for each level. Third-party mock books are fine too, but the official material is the closest thing to the real paper.

Then do the part most people skip. Go through every wrong answer and sort it into one of four piles:

1. Did not know it. A word, kanji or grammar point you have genuinely never learned.
2. Knew it, mixed it up. You have seen it, but you confused it with something similar.
3. Ran out of time. You never got there, or rushed and guessed.
4. Careless. Misread the question, bubbled the wrong number, changed a right answer to a wrong one.

The sizes of those piles are your plan. Pile 1 is the most expensive to fix and the least worth chasing this month, unless it is small. Piles 2, 3 and 4 are where your cheap points are. Most people find that piles 2 and 3 together are bigger than pile 1, which is good news. Those are fixable in four weeks.

If you only take one thing from this article, take this: a mock test you do not review is just an anxious morning.

The Four-Week Plan

The weeks below use the real calendar for this test: today, November 7, is day 1, and the exam on December 6 is day 30. Practice tests land on Sundays, because the real one is on a Sunday, and it helps to get used to sitting for the whole paper on that day.

Week 1 (Nov 7 to Nov 13): Diagnose and patch grammar

• Sat Nov 7 or Sun Nov 8: full practice test, then the four-pile review above.
• Make a short list of every grammar point from pile 2. Usually it is ten to twenty items.
• Each day, take three or four of them. Read a clear explanation, then write two example sentences of your own and say them out loud. Writing your own sentence is what separates "I recognise this" from "I can tell it apart from the one next to it".
• Keep vocabulary review going in the background, fifteen minutes a day, on words you have already met. No new decks.

Grammar comes first because it pays off twice. Fix a confusing pattern and you get the grammar question right, and you also read the passages that use it faster.

Week 2 (Nov 14 to Nov 20): Vocabulary in context and reading speed

• Switch your vocabulary review from single words to words inside sentences. Most vocabulary questions do not ask what a word means on its own. They ask which word fits this sentence, or how the kanji in this sentence is read.
• Do one timed reading passage every day. Time it, write the time down, and watch the number fall over the week.
• When a passage is slow, find out why. It is usually one of three things: an unknown word you got stuck on, a long sentence you could not break apart, or re-reading out of nerves. Each one has a different fix, so it is worth knowing which one is yours.

A useful habit for reading questions: read the question first, then the passage. You are not reading for pleasure. You are reading to find one answer.

Week 3 (Nov 21 to Nov 27): Listening week, plus a second test

• Sun Nov 22: second full practice test, same conditions as the first. Compare the four piles. Pile 3 should be smaller now.
• Make listening the main subject this week: thirty to forty minutes a day, in one block, without pausing the audio. The real test does not pause, so your practice should not either.
• After each set, listen once more with the script in front of you. Mark the exact spot where you lost the thread. That spot is usually a contraction, a fast casual form, or a word you know in writing but did not recognise by ear.

If the second test is still well below the pass mark, this is the week to be realistic about where your remaining points will come from. Put most of your time into whichever section is closest to its minimum.

Week 4 (Nov 28 to Dec 5): Sharpen, do not stuff

• Sun Nov 29: final full practice test. After this one, review your mistakes, but do not take another full test before the real one.
• Spend the week on your own mistake list from all three practice tests. That list is now the most valuable study material you own, because it is made of exactly the things you get wrong.
• Do short, timed sets every day so your sense of the clock stays sharp.
• Stop adding new material by about Thursday, December 3. In the last couple of days, reviewing what you already know is a better use of your time than cramming something new.

What a Normal Day Looks Like

You do not need five hours a day. You need roughly an hour, every day, without skipping. Here is a template for a 60 to 90 minute day:

If you only have thirty minutes on a busy day, keep the timed set and the review and drop the rest. Those two blocks do the most work.

Level-by-Level Priorities

N5

At N5 the test is mostly about whether you know the basics cleanly. The biggest wins this month are usually:

• Particles, especially は vs が and に vs で. These are a large share of grammar questions.
• Kanji readings for the common words, particularly the numbers and dates. 四日よっか, 八日ようか and 二十日はつか are classic traps.
• Listening to numbers, times and prices at natural speed. It sounds easy until three numbers come at you in one sentence.

Our N5 grammar list and N5 reading practice cover exactly this ground.

N4

N4 is where plain form stops being optional. If one thing deserves your week one, it is making sure every pattern that attaches to plain form feels automatic:

✗ 明日あした、雨あめが降ふりますと思おもいます。
✓ 明日あした、雨あめが降ふると思おもいます。
Ashita, ame ga furu to omoimasu.
I think it will rain tomorrow.

After that, look at giving and receiving (あげる, くれる, もらう) and transitive and intransitive pairs like 開あける and 開あく. Both come up again and again. For listening, it is worth getting comfortable with casual forms like じゃない, ちゃう and なきゃ. They turn up in everyday conversation, and they are good practice for following speech that is not slow and polite.

Use the N4 grammar points for the patterns and the N4 reading practice for timed passages.

N3

N3 is the level where the jump in reading catches people. The passages are longer, and they are written the way real Japanese is written, with long modifying clauses in front of the noun they describe.

• Practise breaking long sentences apart. Find the main verb at the end first, then work out what each clause in front of a noun is describing.
• Learn to tell apart the patterns that look alike: ように vs ために, ばかり vs ところ, わけ vs はず. N3 grammar questions love near-synonyms.
• Read something real every day. Short news articles are ideal because they are dense with N3 vocabulary. Our easy Japanese news readings are written at N5, N4 and N3, so you can read the N3 version and check yourself against the easier ones when you get stuck.

The N3 grammar list and N3 reading practice are the two pages to keep open this month.

Section Tactics That Are Worth Free Points

None of these replace knowing the material. They just stop you losing points you already earned.

Answer every question. There is no penalty for a wrong answer, so a blank bubble is always worth zero and a guess is worth something. If time is running out, fill in the rest before the end.

Do not get stuck. If a vocabulary or grammar question is not coming to you in about thirty seconds, mark your best guess, put a small mark next to it on the question booklet, and move on. Come back if you have time. Spending three minutes on one question can cost you a whole reading passage later.

Watch the clock in the grammar and reading section. At N5, N4 and N3, grammar and reading share one time block, and the reading passages come last. Decide before the test roughly when you want to start reading, and stick to it.

In listening, read the options during the pause. For questions with printed answer choices, use the few seconds before the audio starts to read them. Knowing what you are listening for makes a huge difference.

Let go of a missed listening question. You cannot go back. Choose your best guess right away and give the next question your full attention. One missed question is fine. Losing the next two because you were still thinking about it is not.

Be careful with the answer sheet. Check now and then that the question number matches the row you are filling in. Bubbling one row out of place is a cruel way to fail.

The Last 48 Hours

On Friday, December 4, do a light review of your mistake list and nothing else. On Saturday, December 5, do even less: thirty minutes of easy review in the morning, then stop.

It feels wrong to rest the day before a test, but by then your score is mostly decided. A tired brain on Sunday morning will cost you more points than you could gain from a Saturday cram. Instead, use Saturday to:

• Check your test voucher, the exact address of your test centre, and how long it takes to get there.
• Read your centre's test guide again for the check-in time.
• Pack your bag (see below).
• Go to bed at a normal time.

Test Day Checklist

Check-in and late-arrival rules vary by test location. Several overseas centres have added a check-in period for December 2026 and will not let you in once it closes. Even where you are allowed to sit later sections, missing the first one means you cannot pass. Follow your own test centre's instructions for your level, and plan to arrive early.

Bring:

• Your test voucher, filled in as your test centre asks.
• Photo ID, if your centre requires it.
• Pencils and an eraser, as listed in your test guide.
• A simple wristwatch. Phones and other electronic devices must be switched off and put away for the whole test.
• Water and something small to eat during the breaks.

In the breaks, do not discuss answers with other people and do not check your phone for "what was the answer to question 12". The section is finished. The only section that matters now is the next one.

Tools for the Month

All free, and useful for the plan above:

• Grammar by level: N5, N4 and N3 for clear explanations and quizzes on every point.
• Japanese grammar quiz for a quick check on your pile-2 grammar.
• Japanese vocabulary quiz for daily review in context.
• Japanese reading practice for timed passages at your level.
• Easy Japanese news for a new real-world reading every day, written at N5, N4 and N3.
• Kanji to hiragana converter for any reading you are not sure of.

Listening is the section a book cannot fully train, because it is about hearing Japanese at real speed and answering without time to translate. Benkyō: Speak & Learn Japanese gives you short spoken conversations every day at your level, which is a good way to fit listening practice into a busy month.

Four weeks is not long, but it is long enough to make a real difference to your score if you spend it on the right things. Take the practice test this weekend, be honest about the four piles, and let your own mistakes set the plan. Good luck on December 6. がんばってください！
