From a genuine standing start — no hiragana, no vocabulary — plan on three to six months at 8 to 12 hours a week.
If you already read hiragana and katakana comfortably, two to three months is realistic.
Those ranges are wide because the honest answer depends on four things, and none of them is how clever you are.
What actually changes the timeline
1. Whether you can already read the scripts. This is the biggest single factor. Hiragana and katakana take most people two to three weeks to learn and several more to make automatic. Until they are automatic, every other part of the test is slower, because you are decoding letters instead of reading words. Students who arrive already reading them save roughly a month.
2. How many hours a week you can genuinely protect. Not how many you intend to study — how many survive contact with your actual shift pattern. Six real hours a week beats twelve aspirational ones. Be pessimistic here; the plan only works if it is true.
3. Whether your study is spread out or bunched up. Four sessions of 45 minutes across a week beats one three-hour Sunday session, by a wide margin, for vocabulary retention. This is the most reliable finding in language learning and the one most often ignored.
4. Whether you practise under exam conditions. Students who only ever do untimed exercises consistently underperform their practice level on the day. The test is 60 minutes, self-managed, on a computer. Practising any other way trains a different skill.
A realistic 12-week plan
This is roughly what we run, for someone starting from zero at about 10 hours a week.
Weeks 1–3 — Script and survival. Hiragana and katakana to automatic recall. The first 300 words. The sentence patterns the test leans on hardest.
Weeks 4–6 — Everyday situations. Shops, clinics, workplaces, transport. Start Conversation and Expression now, not later — it is the section students most reliably underestimate, because “what would a person actually say here” is a different skill from knowing the grammar.
Weeks 7–9 — Speed. Audio played once, at natural pace. Notices and short signs under a timer. This is where the untimed practice stops.
Weeks 10–12 — Full mocks and repair. One timed full-length mock per week, then rebuild the week around whatever it exposed.
How to know you are ready
Not by feeling ready. By this test:
Two full-length, timed mock tests, on a computer, in the same week, both at 200 or above.
Two, because one good mock is noise. Timed, because time management is a scored skill here. On a computer, because JFT-Basic is a CBT and reading Japanese on a screen is measurably different from reading it on paper.
Clear that bar and book the test. Miss it and you have saved yourself a test fee, which is the entire point.
The most expensive mistake
Booking too early.
We see it constantly: someone books a date, uses it as motivation, does not hit the level, and pays the fee to find out what a free mock test would have told them for nothing. The test fee is real money, and for many of our students it is a meaningful amount of it.
Book the date when the mocks say to. Not before.
