ExploreAbout this exam
The Japanese semi-medium licence (準中型免許, jun-chūgata menkyo) sits between the ordinary licence and the medium licence. It allows you to drive vehicles above the ordinary-licence ceiling - broadly, trucks and other vehicles with a gross vehicle weight up to 7.5 tonnes and a maximum load of 4.5 tonnes - while remaining considerably easier to obtain than the medium licence. It is aimed at drivers who need to work with light-to-mid trucks: delivery and logistics staff, construction and utilities crews, rental and fleet drivers, and people whose employer requires them to handle vehicles beyond the ordinary class. The written test is multiple choice and is delivered in Japanese. It covers road traffic law and driving regulations (the largest share), traffic signs, markings and signals, safe driving and hazard perception, vehicle handling and maintenance, loading, towing and dimension/weight limits, emergency procedures and first aid, and the licensing and penalty system. Preparation means working through the official study text for your licence class, drilling sign and marking recognition until it is automatic, and doing practice papers under time pressure so that long, double-negative questions do not catch you out. The test is written for a careful driver, not a specialist, so consistent revision beats cramming. The official bodies publish current details of the examination and its procedures; check their sites for the figures that apply to you.
What you'll study
About Japan Semi-Medium Theory preparation
What can I actually drive on a semi-medium licence?
It covers vehicles beyond the ordinary-licence limits, up to a gross vehicle weight of 7.5 tonnes and a maximum load of 4.5 tonnes, subject to the conditions attached to your licence. It does not extend to the heavier vehicles reserved for the medium and large classes. Confirm the exact limits against the current official text before you rely on them.
Is the written test multiple choice?
Yes. It is a multiple-choice paper delivered in Japanese, with true/false style statements and scenario-based questions drawn from the full syllabus. There is no essay or oral component in the written stage. Reading speed in Japanese matters as much as knowledge, so practise with full-length papers rather than single questions.
How long is the test and what score do I need to pass?
The official examining body sets and publishes the current time limit and passing score, and these are not fixed figures you should assume. Check the official site for the values in force at your test centre. Do not rely on numbers quoted in forums or older study guides, which are often out of date.
How hard is it compared with the ordinary licence test?
The style is similar but the content is broader: weight, load and towing rules, vehicle inspection points and accident-response duties carry real weight. Most candidates find the difficulty lies in the volume of rules and the tricky wording, not in the concepts. Solid sign recognition plus timed practice papers is usually enough.
If I fail, can I retake it, and how soon?
Retakes are generally possible, but the schedule, any waiting period and the fee are set by the official body and vary by test centre. Check the official site or ask at the centre where you sat the test. Do not assume you can sit again the same day.
What should I study first?
Start with traffic signs, markings and signals - they are finite, highly visual and appear throughout the paper. Then work through road traffic law and driving regulations, which carry the largest share of marks. Add vehicle handling, loading and emergency response afterwards, and finish with the licensing and penalty rules, which are the smallest block.
What are the most common ways candidates lose marks?
Misreading double negatives and absolute words such as 'always' and 'never'; confusing similar signs or marking meanings; and guessing at weight, load and towing limits instead of knowing them. Skipping the emergency and first-aid section also costs easy marks. Slow down on long statements and read the final clause before choosing.
Do I need to study the practical driving material for the written test?
The written paper tests knowledge, not driving skill, but it does include vehicle handling, inspection and maintenance points, and safe-driving judgement. Those questions reward understanding how a vehicle behaves when loaded or braking. Study them as knowledge items rather than as practical lessons.
Is this site or guide officially connected to the Japanese licensing authorities?
No. This is independent study material and is not affiliated with, endorsed by or produced by any licensing authority or test centre. Always treat the official study text and the official body's published procedures as authoritative, and use independent guides only as extra practice.
