How long does it take to learn Japanese? The unhelpful answer is “it depends”. The useful answer is that it depends on four specific things, and once you know what they are you can put a real date on your own goal.

This is a realistic timeline written by native Japanese teachers who teach adults in the UK. It is not the encouraging version and it is not the discouraging version. It is what we tell people in a trial lesson when they ask.

First, define what “learn Japanese” means to you

Most disappointment comes from an undefined goal. These are very different projects:

Pick one. A learner aiming at “conversation by next summer” progresses faster than a learner aiming at “Japanese”, because only one of them can tell whether they are on track.

The published benchmarks, and what they actually mean

Two numbers get quoted constantly. Both are useful and both are widely misunderstood.

The US Foreign Service Institute places Japanese in its hardest group for English speakers, at roughly 2,200 class hours to reach professional working proficiency. That figure comes from full-time, intensive training of selected adult learners, so it is a ceiling for a very high standard, not a description of what an evening-class learner is aiming at.

JLPT study-hour estimates are commonly quoted at a few hundred hours for N5, rising steeply towards N1. These vary a lot by source and assume no prior kanji knowledge, so treat them as orders of magnitude rather than targets. Our JLPT preparation guide covers what each level involves.

The practical translation: Japanese is not harder to speak than French. It is slower to read. Almost all of the extra time in those numbers is the writing system.

A realistic timeline at three to four hours a week

This assumes one lesson a week plus twenty to thirty minutes on most days, which is what a working adult can actually sustain.

Weeks 1 to 4

Hiragana, the sound system, greetings and self-introduction. You can read simple words aloud, slowly, and say who you are.

Months 2 to 3

Katakana, basic sentence structure, core particles, the polite ます form, numbers and time. You can order food, ask prices, describe your weekend in short sentences. Around a hundred kanji recognised as words. Our first three months guide sets this out lesson by lesson.

Months 4 to 9

Past and negative forms, te-form and the doors it opens, adjectives, giving and receiving, plain form. Kanji into the low hundreds. You can hold a slow conversation about familiar topics and read signs and menus. Roughly JLPT N5 territory, moving towards N4.

Year 1 to year 2

Conditionals, passive and causative, keigo in its everyday forms, longer sentences. Kanji into the several hundreds. You can have a real conversation with a patient speaker, understand a fair amount of slow television, and read short texts with a dictionary. Around N4 to N3 for a consistent learner.

Year 3 to year 5

Comfortable conversation, reading with growing independence, and the shift from “translating in your head” to understanding directly. N2 is a realistic target in this window for someone who keeps going; N1 usually needs either more hours per week or time spent in Japan.

If those timescales look long, remember that the first band, the one that makes a trip to Japan enjoyable, is measured in weeks.

Five things that change the timeline

  1. Consistency beats intensity. Twenty minutes daily beats three hours on Sunday, by a wide margin. Japanese in the early stages is mostly a memory problem.
  2. Whether you learn kana immediately. This applies if you are learning Japanese as a language: staying on romaji feels faster for a fortnight and costs months later. It does not apply to a short run-up before a trip, where the phrases you can say out loud matter far more than the characters you can read.
  3. Whether you produce or only consume. Making your own sentences, out loud and imperfectly, is what moves you. Passive study feels productive and is not.
  4. Whether anyone corrects you. Uncorrected mistakes harden into habits that take longer to remove than they took to form.
  5. Prior experience of a character-based language. If you already read Chinese characters, cut the reading estimates substantially. If not, they apply.

The three points where people stop

In our experience, learners rarely drift away at random. There are three predictable walls.

Week 3, at hiragana. It feels like memorising a phone book. The way through is to accept it as a two-week job, use short daily sessions, and start reading real words rather than isolated characters.

Month 5, when the beginner glow fades. The novelty has gone and fluency is still far away. This is where a fixed weekly lesson and a specific goal do most of their work.

The intermediate plateau, usually somewhere around N3. You understand a lot and can produce comparatively little. The answer is almost always more output and more reading, not more grammar study.

Knowing these are coming makes them much less personal when they arrive.

What if you only have eight weeks before a trip?

Then do not start a general course. Start with the situations you will be in: ordering, buying tickets, asking for directions, apologising and checking into a hotel. You do not need to read Japanese for any of that, and nothing on that list depends on it. If you do have spare time, learning to spot a few signs by shape rather than reading them, 入口, 出口 and 円 among them, makes the odd moment slightly easier; treat that as a bonus rather than homework.

Eight weeks of focused, situation-based practice will make a trip noticeably better. Eight weeks of a general beginners’ course will leave you able to introduce yourself and not much else. This is why we built Travel Japanese as a separate short block, and we look at how far it gets you in Is a Short Japanese Course Enough Before a Trip to Japan?

Frequently asked questions

Can I learn Japanese in a year?

You can reach comfortable everyday conversation on familiar topics in a year at three to four hours a week. Fluent reading in a year is not realistic for most people starting from zero.

Can I learn Japanese from apps alone?

Apps are good at vocabulary and kana drilling and poor at correction, particles and unscripted speaking. Most learners who use only apps stall somewhere in the first year. They work well alongside lessons.

How many kanji do I actually need?

A few hundred covers most everyday signage and simple text. Around two thousand are used in general published material. Learn them as words in context and the number stops being frightening.

Is Japanese harder than Korean or Chinese?

Grammatically, Japanese and Korean are similar and both are structurally distant from English. Chinese has simpler grammar and harder pronunciation. For an English speaker, the writing system is the main cost in Japanese.

Does taking two lessons a week halve the time?

No. Roughly speaking it helps, but the limiting factor is review between lessons. Two lessons a week without review is usually less effective than one with it.

What each JLPT level actually lets you do

Levels are easier to plan around than years, because they describe capability rather than effort. Roughly, and without the exam jargon:

You do not need to sit the exams to use the levels as milestones, though a booked exam date is one of the most reliable ways to keep momentum. Our JLPT preparation guide covers how the exams work in London.

A twelve-month plan you could actually follow

One lesson a week, twenty to thirty minutes on most other days, and a review point every quarter.

At the end of each quarter, do one thing that tests you rather than comforts you: a level check with your teacher, a mock exam section, or a conversation with someone who does not know your level.

Measuring progress when it feels invisible

The most common reason people conclude they are not progressing is that improvement in Japanese is discontinuous. Nothing happens for six weeks, then a chunk of listening suddenly makes sense. In between, use markers you can see rather than how fluent you feel:

  1. Recognition speed. Time yourself reading a short kana passage aloud once a month. The number goes down even when comprehension feels flat.
  2. Sentences you were never taught. Keep a note of the ones you produce spontaneously. The count rising is the clearest evidence of real learning.
  3. Recovery, not perfection. Early on you freeze when you do not know a word. Later you go round it. Noticing that you went round it is progress.
  4. Re-watch something. Take a scene you watched three months ago and watch it again. What you catch now is the measure.

Learning while working full time

Almost all of our learners have jobs, and the pattern that works is not the one people plan on their first enthusiastic weekend.

What fails: an hour a day every day, starting Monday. It survives about two weeks, and the collapse feels like personal failure rather than a scheduling error.

What works: a fixed weekly lesson you would need a real reason to cancel, twenty minutes on most days, and a deliberate day off. Roughly three to four hours a week, sustained for a year, will take a complete beginner further than ten hours a week sustained for six weeks. Japanese rewards frequency far more than volume, because most of the early work is memory, and memory responds to spacing.

If your weeks are genuinely unpredictable, build the plan around that rather than against it: shorter, more frequent lessons, online rather than travelling, and a teacher who can move a session occasionally.

Put a date on it

The fastest thing you can do for your timeline is to stop learning “Japanese” and start learning Japanese for a specific purpose, with a teacher who plans backwards from it.

Our £24 trial lesson is 45 minutes online with a native Japanese teacher based in London who teaches in English. We will check your level, ask what you want to be able to do, and tell you honestly how long that will take at the hours you can realistically give it.
