JLPT guide
How long does each JLPT level take?
The honest answer is a range — but the range tells you whether December is a plan or a wish.
The question everybody asks, and the only honest answer is a range — but the range is genuinely useful, because it tells you whether the level you are aiming at this December is a plan or a wish.
The commonly quoted hours
These come from surveys of people who passed, and they split on one thing: whether you already read Chinese characters. A Chinese speaker starts the kanji half of the exam most of the way home.
| Level | With a kanji background | Without |
|---|---|---|
| N5 | 250–450 h | 325–600 h |
| N4 | 400–700 h | 575–1,000 h |
| N3 | 700–1,100 h | 950–1,700 h |
| N2 | 1,050–1,500 h | 1,150–1,800 h |
| N1 | 1,700–2,600 h | 3,000–4,800 h |
They are cumulative — the N2 row is total hours from zero, not hours from N3. And the ranges are wide because they are measuring people, not curricula.
What that means in months
At one hour a day, N4 from zero is roughly two years. At three hours a day it is eight months. The JLPT runs twice a year, in July and December, so the arithmetic that matters is hours-per-week against the number of weeks left, and it is worth doing honestly once rather than optimistically every week.
Why N1 breaks the pattern
Look at the last row. Without kanji, N1 is not one step past N2 — it is most of another N2 again. The vocabulary roughly doubles, the reading turns to editorial and academic prose, and the listening assumes you are following an argument rather than a conversation. People who cleared N2 in a year routinely spend two more on N1.
Hours are an input, not a measure
Nobody has ever passed on hours. What decides it is whether you can finish the reading in the time given and clear the minimum in every section — and the only instrument for that is a timed paper.
Sit one now, at the level you are aiming for, and again every few weeks. The section breakdown tells you where the hours should go next, which is the part a study plan cannot guess: N5 · N4 · N3 · N2 · N1.
