Japan High School Entrance Exams: The Dual Evaluation Explained
Japan high school entrance exams decide nearly every student's next school through a dual evaluation: a written test plus the 内申書 (naishinsho, "internal school report") that the middle school submits.12 Families that prepare only for exam day miss half the contest, because daily grades already count before the test booklet opens.
Procedures, fees, and requirements can change. Confirm current details at the Tokyo Metropolitan Board of Education admissions pages for Tokyo, or with your prefectural board of education for local exam rules.
Overview
High school is not compulsory in Japan, yet about 99 percent of middle-school graduates continue to one.3 Admission is the gate, and it works differently from the automatic district assignment of elementary and middle school. Every applicant competes, and every prefecture runs its own contest.
The system has two pillars. The written entrance exam tests five subjects on one day, while the naishinsho carries three years of classroom performance into the decision.1 Public schools use prefecture-wide exams set by the prefectural board; private schools set their own exams school by school.4 The sections below explain each component, the January-to-March calendar, the recommendation alternative, and the strategy open to foreign-resident families.
The Two Components: Exam Score and Naishinsho
Selection committees read two numbers side by side. The exam score shows what the student produced on test day, and the naishinsho shows what the student produced across three years. Neither alone decides most admissions; together they form the dual evaluation that gives this article its name.
The five-subject written exam
The standard public written exam covers the 五教科 (gokyōka, "five school subjects"): Japanese, mathematics, English, science, and social studies.12 Each prefectural board writes its own paper, so difficulty and style shift at prefectural borders. A student who moves from Osaka to Tokyo mid-year faces a different test, not just a different school.
Private schools set school-specific exams instead. Most test three to five subjects with their own difficulty and format, and competitive schools add their own essay or interview on top.1 National attached schools run similarly school-specific exams at high difficulty.
Prefectural boards and schools publish past papers, and commercial collections reprint them with answer keys. Practicing a neighboring prefecture's paper trains the wrong test, so confirm the paper's origin before buying a workbook.
The naishinsho report from the middle school
The 内申書 (naishinsho, "internal school report") is the middle school's formal record of the student's grades and conduct, sent directly to each high school applied to.12 It compresses classroom grades, attendance, and behavior assessments across the middle-school years into the school's official statement about the applicant. Students never write it and parents never see its final form before submission.
Third-year performance carries the heaviest weight in most prefectures' scoring. That timing matters: the report is largely fixed before the winter exam season begins, so a weak autumn cannot be fully repaired by a strong February.1 Families should treat every regular term test from the first year onward as part of the entrance campaign.
The Annual Schedule: January to March
The public admission calendar compresses into three months. Applications go in during January, the written exam falls in February, and results are announced in March for April entry.41 The diagram below shows the spine of the season.
Private-school cycles often start earlier, with some schools accepting applications from autumn and examining through February depending on the school.1 A student applying to both a private safety school and a public first choice juggles two calendars at once, and the private result sometimes arrives before the public exam date.
Most prefectures restrict applicants to a single public school per admission round, which makes the safety-school plan a private-school matter. A few prefectures run second rounds for unfilled seats, so read the local board's current-year guidelines rather than assuming last year's rule.
The Recommendation Track (Suisen Nyushi)
The 推薦入試 (suisen nyūshi, "recommendation-based entrance exam") fills a smaller share of seats through middle-school recommendation rather than open written competition.1 The middle school nominates students based on grades and special skills, and the high school selects through interviews and short essays instead of the full five-subject paper. Successful applicants commit early and typically cannot continue to the general exam for other schools.
This track suits students with strong cumulative records and a clear first-choice school. It does not suit late bloomers, since nomination depends on the same naishinsho record the general track weighs. Families considering it should ask the homeroom teacher about nomination standards a full year ahead, not in the application term.
Public, Private, and National Exam Differences
The three school tiers set exams through three different bodies. Prefectural boards write the public paper, each private school writes its own, and each national attached school writes its own at selective difficulty.41 Preparation therefore forks early: public-track students drill the prefectural paper format, while private-track students drill each target school's format.
Difficulty ladders form within each prefecture rather than nationally. A top public school in one prefecture may admit at scores that would rank mid-tier in another, so cross-prefecture comparisons mislead. Judge selectivity from the local board's published score bands and each school's applicant-to-seat ratios.
The Foreign-Family Strategy
Foreign-resident students face the same dual evaluation by default, and foreign-family guidance materials present 塾 (juku, "cram school") supplementation as the typical preparation rather than optional enrichment.1 Three years of Japanese-medium grading feed the naishinsho, so students who arrived recently compete on a report built partly in another school system.
Where a prefecture operates a foreigner special-quota track, a second door opens with fewer subjects and accommodated Japanese testing (see the quota discussion in this subcategory's companion coverage).56 The two paths are not mutually exclusive in planning: many families prepare for the standard exam while verifying quota eligibility in parallel. Confirm which door fits before committing preparation time to only one.
Good to know
Third-year grades count before the exam season starts
The naishinsho consolidates middle-school performance, with third-year results weighing heavily. A student who coasts through autumn and crams in winter repairs only the exam half of the evaluation.1 Treat term tests as entrance exams in miniature from the first year.
One public school application per prefecture round in most prefectures
Prefectural rules typically allow a single public-school choice per admission round.41 That constraint shapes the whole strategy: the public application expresses the true first choice, while safety options come from private schools with separate exams and calendars. Verify the current-year rule with the local board, since second-round procedures for unfilled seats change periodically.
Juku is the norm, not the exception, on competitive tracks
Guidance materials for foreign families describe juku attendance as standard preparation for selective schools.1 Costs and schedules vary widely by provider and course load, so families should compare monthly fees and February-intensive charges before enrolling. Starting in the second year spreads both cost and workload.
Essays and interviews are spreading beyond the written test
Tokyo and other prefectures document interview, essay, and group-discussion components alongside the five-subject paper.41 These formats reward students who can explain reasoning aloud, not just solve silently. Practice should include spoken answers and timed short essays, particularly for recommendation-track and selective-school applicants.
