ExploreAbout this exam
The Ishi Kokka Shiken (医師国家試験, Physician National Examination) is Japan's licensing examination for physicians. Passing it, together with completion of the required clinical training, allows registration as a physician in Japan and is the final step for graduates of Japanese medical schools as well as for candidates who qualify through other recognised routes. The exam is delivered in Japanese and is built almost entirely around multiple-choice questions, including case-based items that ask you to reason from a short clinical vignette to a diagnosis, next step, or underlying mechanism. Coverage is broad: basic medical sciences, internal medicine, surgery and its subspecialties, paediatrics, obstetrics and gynaecology, psychiatry and neurology, emergency and critical care, public health and social medicine, medical law and ethics, and clinical skills and communication. Preparation usually takes the form of a long, staged review of the core sciences followed by heavy practice with integrated cases and image-based items, plus repeated self-testing under time pressure. The official bodies publish the current schedule, fees, eligibility rules, question structure and scoring information each year, so always confirm those details at the source rather than relying on second-hand summaries.

What you'll study
About Ishi Kokka Shiken preparation
What is the exam format?
It is a multiple-choice examination delivered in Japanese over several days of testing. Items include standalone knowledge questions and case-based questions that present a short vignette, sometimes with laboratory data, and ask for a diagnosis, the most appropriate next step, or an underlying mechanism. Confirm the current structure on the official site.
How hard is it, and what is the pass rate?
It is a demanding, high-volume examination that assumes you have completed a full medical curriculum; most candidates spend several months on dedicated review. Pass rates vary by year and by candidate category, so the official examining body publishes the current figures. Check its site rather than relying on numbers quoted in forums.
Can I retake the exam if I fail?
Yes, retaking is possible, and many candidates do. The rules on how often and under what conditions differ by candidate category, and the official body publishes the current retake policy. Read the eligibility section carefully before planning a second attempt, and build your study plan around the areas that cost you marks.
How much does it cost and how long does it take?
Fees and the exact examination schedule change from year to year. The official examining body publishes the current fee, application window and examination dates on its site. Plan your application early, because document deadlines are strict and missing them cannot be fixed after the fact.
Should I study basic sciences or clinical subjects first?
Start with the basic sciences and pathology, because clinical reasoning questions are much easier when the mechanism is automatic. Then move to internal medicine as your anchor, and layer surgery, paediatrics, obstetrics and gynaecology, psychiatry and neurology on top. Keep public health, ethics and law in a steady weekly slot rather than cramming them at the end.
How should I use practice questions?
Use them as a diagnostic tool, not a scoreboard. After each block, write down why the wrong options were wrong and which fact you were missing. Revisit those notes weekly. Timed full-length practice under exam conditions matters too, because pacing across several days of testing is a skill in itself.
What are the most common failure modes?
Candidates most often fail through shallow coverage of broad subjects, ignoring public health, ethics and law, and never practising under time pressure. Another common error is reading explanations without testing recall. Passive review feels productive but does not build the retrieval speed that case-based items demand.
Do I need to memorise Japanese medical terminology?
Yes. The examination is delivered in Japanese, and disease names, drug names and anatomical terms appear in kanji and katakana forms. If you trained abroad, practise reading Japanese vignettes and laboratory reports early, because terminology slows you down before clinical reasoning even begins.
How do clinical skills and communication get tested?
They appear as written items covering interviewing, history taking, physical examination findings, informed consent and professional behaviour, rather than as a live practical test in the written examination. Study them alongside ethics and law, since the reasoning overlaps, and practise choosing the most appropriate next communication step.
