A language school's core product is student-visa sponsorship. If you are already in Japan on a work visa, that product is worth nothing to you, and you would be paying ¥610,000–1,900,000 a year for contact hours you can partly get free. The JLPT does not care where you studied.

Community class vs language school (2026)

|---|---|---|
| Contact hours per week | ~2–4 vs ~20 | Path2Japan estimate |
| Cost per year | ¥0–20,000 vs ¥610,000–1,900,000 | JASSO |
| Sponsors a student visa | No vs Yes | MEXT survey (FY2023) |
| Issues a certificate | Neither — N2 comes from the JLPT | Path2Japan estimate |
| Teachers who are volunteers | 23,281 of 46,257 nationally (50.3%) | MEXT survey (FY2023) |
What you are actually buying
Look at the national numbers and the business model becomes obvious. Japan’s accredited language schools (法務省告示機関) teach 122,001 learners — more than every other category combined. Yet they are only 634 institutions out of 2,727 teaching bodies nationwide.
Why do they concentrate so many learners? Because they are the only bodies that can sponsor a 留学 student visa. That is the product. The teaching is real, but the thing you cannot get anywhere else is the visa.
Which leads to the question this page exists for: if you are already in Japan on a work visa, what exactly are you paying for?
The comparison, honestly
| Community class | Language school | |
|---|---|---|
| Cost per year | ¥0–20,000 | ¥610,000–1,900,000 |
| Hours per week | ~2–4 | ~20 |
| Student visa | No | Yes |
| Curriculum | None — mixed level | Structured |
| Certificate | No | No (N2 comes from the JLPT) |
Two rows deserve attention.
The 5–10× hours gap is real. A volunteer class once a week will not take you from zero to N2 in eighteen months. Anyone telling you otherwise is being kind rather than accurate.
Neither issues a qualification. N2 comes from sitting the JLPT, an open exam. Your certificate does not record where you studied — a point that quietly demolishes the main reason people assume they need a school.
So who actually needs one
You do if: you need a student visa; or you have decided to stop working and study intensively; or you are going on to a senmon gakkō or university that expects a school record.
You probably do not if: you already hold a work visa, you can study a few hours a week around your job, and your target is functioning in Japanese rather than a school-to-school progression.
What the second route looks like
- A community class — free or a few hundred yen, once or twice a week. This is your speaking practice and your correction loop, and half of Japan’s Japanese teachers are these volunteers.
- Self-study for grammar and kanji — the part a mixed-level volunteer class cannot systematise for you.
- A private tutor if you can afford it — ¥2,000–4,000 an hour buys targeted work on your weak points; ten hours of that costs less than a month of school.
- Book the JLPT — not for the certificate itself but for the deadline. Nothing structures self-study like a paid exam date.
That stack costs a fraction of ¥610,000 and is a legitimate way to reach a working level. It is slower than full-time school. It is also the route most working adults in Japan actually take, because they have jobs.
Common mistakes & warnings
- Do not read this as "language schools are a scam". They are the only route to a student visa, and full-time intensity is genuinely hard to replicate alone. The point is that you should know which of the two things you are buying.
- Free community classes run 1–2 times a week with no curriculum. If you go this route, you are the one supplying the structure — decide that consciously rather than drifting.
Frequently asked questions
I have a work visa and want N2. Do I need a school?
No. The JLPT is an open exam; nobody asks where you studied. What you need is contact hours and structure. A community class covers speaking and correction; self-study or a private tutor (¥2,000–4,000 an hour) covers grammar and reading.
So what is a language school actually for?
Three things: sponsoring a student visa, delivering ~20 hours a week of structured instruction, and producing a school record. If you need the first, nothing substitutes. If you only want the second, you can approximate it. The third rarely matters outside school-to-school progression.
Is the free class really enough to work in Japanese?
For daily life and workplace conversation, often yes — combined with actually being at work in Japanese every day. For reading business documents at speed, no route is quick, school or not.
What would you actually do in my position?
Start at a [community class](/en/study/community-japanese-classes/) this month because it costs nothing and you meet people. Add self-study for grammar. Book the [JLPT](/en/study/jlpt-guide/) to force a deadline. Only buy a school if you need the visa or you have decided to stop working and study full time.
