There is no age limit on JFT-Basic. Anyone can sit it - see who can take it. The Specified Skilled Worker route itself requires you to be 18 or over, with no upper bound in the language requirement.
That is the administrative answer. The practical question - is it harder at 45 than at 20 - deserves a more honest one.
What is genuinely different
Time is the real constraint. Most older candidates are working full time, often supporting a family. The difference in outcomes between a 22-year-old and a 45-year-old is usually hours per week, not capacity.
Rote memorisation is slightly slower, and the effect is smaller than people fear. It is comfortably offset by the next point.
You are better at structure. Older learners plan, keep to schedules, and tolerate boring drilling - which is most of what this exam rewards. Vocabulary and set phrases do not need insight. They need repetition, done consistently.
Handwriting habits do not matter here. You are never asked to write kanji on JFT-Basic. Recognition is the whole skill: kanji requirements.
What actually holds older candidates back
Two things, in our experience, and neither is age:
Studying in long, rare sessions. A three-hour Sunday session is worse than twenty minutes daily. Memory responds to spacing, not to duration - spaced repetition.
Not rehearsing the computer. Candidates who have not used a computer test before lose marks to the interface rather than the Japanese. This is entirely fixable in two sessions: sit our free exam demo on a laptop and the format stops being unfamiliar. What the screen does.
A realistic schedule for a working adult
- Weekdays: 20-30 minutes, split. Vocabulary on the commute, listening while cooking.
- One weekday evening: 45 minutes of grammar or a class.
- Weekend: one 60-minute mock, fortnightly, on a computer.
That is around five hours a week, and it reaches JFT-Basic level in four to six months from a genuine beginner start. How long it takes breaks the range down.
Studying around shift work has its own guide: studying Japanese while working full time.
About employability
JFT-Basic certifies language ability and nothing else. Employers in SSW sectors recruit for reliability and relevant experience, both of which older candidates usually have more of.
What matters is the sector: the sectors list sets out the fields, several of which - care in particular - explicitly value maturity.
Start with a measurement
Before planning anything, find out where you are. The free practice test is untimed and explains every answer in your own language; the exam demo is the full 60-minute thing.
A measurement is worth more than a month of guessing about whether you are the right age for this.
