There is no official JFT-Basic vocabulary list. The Japan Foundation does not publish one, and any site presenting a numbered list as “the official JFT-Basic words” is presenting its own guess as fact.
What can be said honestly is this: JFT-Basic tests Japanese at A2 on the CEFR scale, in daily-life and workplace situations. Working backwards from that, a realistic active recognition vocabulary for a comfortable pass is in the region of 1,500 to 2,500 words.
Treat that as a planning figure, not a target to tick off.
Why the range is so wide
Because the number is the wrong variable. Two candidates with 2,000 words can get very different scores depending on which 2,000.
JFT-Basic is built around a specific world: living and working in Japan. Someone who has learned 2,000 words of textbook Japanese weighted towards student life — university, classes, hobbies, travel — will underperform someone with 1,500 words weighted towards shops, transport, times, workplaces, hospitals and housing.
Relevance beats volume, and on this exam the gap is large.
The vocabulary that actually earns points
In rough order of return:
- Numbers, times, dates, counters. They appear in every section and they decide listening and reading answers outright. A question hinges on 9時50分, not on a difficult noun.
- Everyday actions. かいます, いきます, きます, たべます, つかいます, まちます and their forms.
- The workplace. Shifts, breaks, instructions, permission, apologising, reporting a problem.
- Shops and services. Prices, sizes, asking where something is, this one rather than that one.
- Transport. Stations, lines, stopping and not stopping, being late.
- Health and housing. The hospital, the landlord, rubbish rules.
- Adjective pairs. たかい/やすい, ちかい/とおい, おおきい/ちいさい. The exam likes opposites.
If you only had two weeks, that list in that order would be a better use of it than any general word book.
How to learn them so they stick
Spaced repetition, every day, small. Twenty new words daily with review of everything before. Not two hundred at the weekend.
Learn confusable words together. The exam’s wrong answers are built out of near-misses: 電車 and 電話, 病院 and 美容院, かいます and かえます. A word learned alone is not protected against the word it will be confused with. Put them on the same card.
Recognition, not production. You never write Japanese on JFT-Basic. Being able to recognise でんしゃ and 電車 is the requirement; being able to write 電車 from memory is a different and much more expensive skill.
In sentences, not in lists. A word learned inside a sentence you could say carries its particles and its register with it. A word learned as a translation pair does not.
How to know when you have enough
Not by counting. By testing.
Sit a full-length timed test and look at the section breakdown. If Script and Vocabulary is strong and you are still short of 200, more words is not your problem. If whole reading passages are opaque rather than tricky, it is.
The free practice test gives you that breakdown in about fifteen minutes. It is a much better guide to what to study next than any word count.
