What the official source says
The Japan Kanji Aptitude Testing Foundation runs the BJT. By their own description, it isn't a vocabulary or grammar test — it measures whether you can take information from a Japanese business setting and act on it appropriately.
| Section | Time and questions | What to train |
|---|---|---|
| Listening | ~45 min, 25 questions | Scenes, speaker roles, intent, short conversations |
| Listening and Reading | ~30 min, 25 questions | Audio plus tables, notices, documents, conditions |
| Reading | 30 min, 30 questions | Vocabulary, grammar, business expressions, documents |
There's no pass or fail. You get a score from 0 to 800 and a rank from J5 to J1+. The goal isn't to clear a line — it's to find which section is leaking points and push that one up.
Where BJT listening gets you
The first thing you do isn't translate — it's work out who's talking to whom. Boss to junior? Client to vendor? Inside the company or outside? Get this wrong and every later call goes off the rails.
Listening-reading adds another layer. While the audio plays, you're also scanning a table or notice for the part that matches what you just heard. Miss a date, a number, or a name, and the answer slips by.
- Who's talking: superior, peer, client, vendor — this is what decides the "right" wording.
- What they actually mean: polite Japanese softens refusals, hesitation, and requests until they almost disappear.
- Where it is on the page: dates, numbers, names, headers — the anchors that get you to the answer fast.
What past test-takers keep saying
On Reddit, the line you see most often is that BJT is way more "business" than people expect. Meetings, client calls, internal memos, the polite-form distinctions you only pick up at work — all of it shows up on the test.
A lot of N1 holders say their general Japanese alone wasn't enough. Without office experience, scores stay flat.
These are personal accounts, not data. But the same advice keeps coming back: drill business Japanese until it's automatic, so on test day your attention can go to the situation, the document, and the answer.
How to actually train for it
Start with the official samples
Get used to the question types, the CBT layout, and what information shows up on screen before the audio plays. Walking into the real test cold costs you points just from the format.
Lock in the relationship before anything else
The first seconds of audio: is it internal or external, senior or junior, client or vendor? Without this, you have no basis to judge keigo or intent.
Sort your mistakes by cause
When you miss a question, ask yourself: did I not hear the word, did I hear it but not know it, or did I get the meaning wrong? Each cause needs a different fix. Skip the sorting and you'll keep missing the same way.
Scan the document first, then listen
Before the listening-reading audio kicks in, eyes straight to dates, numbers, names, departments, headers. When the audio mentions a number, you already know which row to check.
Practice fast, review at normal speed
Running practice at 1.1× or 1.25× builds pressure tolerance. But review has to be at normal speed — if you can't explain the answer at full speed, faster practice won't fix that.
Drill the polite forms until they're automatic
「承知しました」「かしこまりました」「恐れ入りますが」— knowing the meanings isn't enough. Drill them until they fire on reflex, so your attention can stay on intent and document.

FAQ
Is BJT Prep official?
No. BJT Prep isn't affiliated with the test. For registration, fees, and the official rules, go to the BJT website and Pearson VUE.
Can I prep for BJT using only JLPT materials?
JLPT materials are useful for general Japanese, but BJT pulls from a different pool. Business situations, keigo distance, audio-with-document tasks — none of that gets practiced in JLPT prep.
Practice in Japanese, like the real test
The practice interface stays Japanese-only — same as the actual exam. Answer at test pace, then read the Japanese explanation. Replay any choice on its own, at whatever speed you want.
