About this exam

The 警察官採用試験 is the entry route into Japan's prefectural police forces and, for some applicants, the national police agency. Each prefecture runs its own recruitment examination, so the content, schedule and difficulty vary by force; the National Police Agency hires separately. The examination is for Japanese nationals (or those meeting each force's nationality and residence conditions) who want a career as a police officer, and it is taken by high school, junior college, university graduates and experienced adults through separate tracks. Written testing typically covers constitutional law, administrative law including the 警察官職務執行法, criminal law, criminal procedure, civil law, general knowledge and current affairs, Japanese language, and numerical reasoning, alongside an essay (小論文), aptitude and personality testing, a physical fitness test, an oral interview and a medical examination. Because the legal questions reward precise recall of statutes and case law while the 数的処理 and 国語 sections reward speed, strong candidates build a study plan that mixes memorisation with timed practice. Read the current guidelines on the recruiting force's official website, since eligibility, schedule and the exact subject mix are set there and change between years. Preparation usually takes several months of consistent daily work, and interview and physical readiness deserve as much attention as the written papers.

What you'll study

Common questions

About Japan Police Exam preparation

Who runs the exam, and is it the same everywhere?

No. Each prefectural police force sets its own recruitment examination, and the National Police Agency recruits separately. Subjects overlap heavily, but eligibility, schedule, essay topics and physical standards differ. Always download the current 採用案内 from the force you are applying to rather than relying on another prefecture's guide.

What does the written test actually look like?

Most forces use multiple-choice papers in law subjects, general knowledge, Japanese language and numerical reasoning, often with a separate essay. Some tracks add a specialised or short-answer paper. The mix depends on whether you apply through the high school, university graduate or experienced-adult route, so check the subject list for your track.

How many questions are there and how long do I get?

These figures are set by each recruiting body and change between recruitment rounds, so no fixed number applies across Japan. The current question count, time limit and scoring are published in the official recruitment guidelines for the force and track you are applying to; confirm them there before you build a practice schedule.

Is the exam difficult?

The law papers are demanding because they test precise statutory wording and leading case law rather than general impressions. The bigger filter for many candidates is the combination of speed on 数的処理, clarity in the essay, and performance in the interview and physical tests. Balanced preparation matters more than depth in one subject.

Can I retake it if I fail?

In practice, yes. Recruitment examinations are held on a recurring schedule, and age limits define how long you remain eligible, so most candidates can apply again in a later round. The specific rules on reapplying, age limits and any waiting periods are set by the recruiting force, so verify them in the current guidelines.

How long should I study before the exam?

Three to six months of steady daily study suits most candidates, with more time if you are new to law. Start with criminal law and criminal procedure, which carry heavy weight and connect to the 警察官職務執行法, then add constitutional and civil law, and keep 数的処理 and 国語 in short daily sessions so speed improves gradually.

Where do most candidates lose points?

Common weak spots are mixing up similar statutory provisions, misreading the question stem in 数的処理 under time pressure, and writing a 小論文 that states an opinion without structure or a counterargument. Interview answers that sound rehearsed and vague about why you want to be an officer also cost points.

How should I prepare for the essay and interview?

For the essay, practise a fixed structure: state your position, give two reasons with concrete examples, address the opposing view, and conclude. For the interview, prepare specific episodes from your own life that show judgement and teamwork, and rehearse them aloud. Both improve faster with feedback than with silent reading.

What should I do about the physical fitness test?

Start training early rather than in the final weeks. Typical events test endurance, strength and agility, and the standards differ by force and by track, so confirm the exact events and passing criteria in the official guidelines, then train specifically for them while avoiding injury close to the test date.

Where can I find official details on dates, fees and results?

Only the recruiting body publishes authoritative information on application periods, examination dates, fees, passing criteria and results. Check the official website of the prefectural police force you are applying to, or the National Police Agency for its own recruitment, and treat third-party summaries as leads to verify, not as sources.
