About the Ibaraki Entrance Math Exam
The Ibaraki Public High School Entrance Examination mathematics paper is created by the Ibaraki Prefectural Board of Education. The single 50-minute, 100-point paper, sat on February 26, 2026 in the Reiwa 8 general selection, is a written exam on the 2017 MEXT junior-high Course of Study, organized into six major questions covering small-problem calculation sets, probability, plane geometry with proofs, linear functions, and solid geometry. Answers are entered on a printed answer sheet, mostly as a final value with some lettered-choice items, and geometry proofs are a noted Ibaraki feature. Admission combines the 500-point academic test with the 135-point junior-high report card (grades 1–3, nine subjects) with the two weighted roughly equally. This page provides 100 original English-language practice questions with detailed explanations as a study adaptation — not an official translation or a simulation of the official format.
Assessment
The real Ibaraki mathematics examination is a 50-minute paper scored out of 100 points (500 total across five subjects: kokugo, social studies, mathematics, science, and English including a listening test); in the Reiwa 8 (2026) general selection it was sat on February 26, 2026 (Thursday), with selection results announced on March 11, 2026 (Wednesday) at 9:00. The paper is created by the Ibaraki Prefectural Board of Education on the 2017 (Heisei 29) MEXT junior-high Course of Study, organized into six major questions: small-problem calculation sets (ōmon 1–2), probability (ōmon 3), plane geometry with proofs (ōmon 4, a noted Ibaraki feature), linear functions (ōmon 5), and solid geometry (ōmon 6). Answers are entered on a printed answer sheet, mostly as a final numeric or algebraic value with some lettered-choice items.

Ibaraki Entrance Math Study Tips from Top Performers
Frequently Asked Questions
Is the real Ibaraki mathematics entrance paper multiple-choice?
Not entirely. Ibaraki's mathematics paper mixes lettered-choice items with items where you write a final numeric or algebraic answer on the answer sheet, and the paper is organized into six major questions (small-problem sets, probability, plane geometry, linear functions, and solid geometry). So option-picking is part of the real paper, but you must also produce the answer yourself. This bank is an English-language four-option MCQ study adaptation, not official past problems or a reproduction of the official layout: real selection items are not limited to four options, and every stem is in Japanese. Work past papers under time pressure — six major questions with many sub-questions in 50 minutes leaves well under two minutes each.
Are these questions official past exam problems?
No. Although the Ibaraki Prefectural Board of Education publishes the actual examination problems after each sitting, it does not publish them as a multiple-choice set. This bank is an original English-language MCQ study adaptation aligned to the 2017 MEXT junior-high Course of Study, with genuine worked-calculation items across numbers and expressions, equations, functions, geometry, and probability.
How long is the mathematics paper and what is the maximum score?
The mathematics paper is a single 50-minute exam scored out of 100 points, sat on February 26, 2026 in the Reiwa 8 general selection. The five subjects total 500 points and are combined with the 135-point junior-high report card (naishinten) in selection, with the academic test and the report card weighted roughly equally.
How is the naishinten (report card) score calculated in Ibaraki?
Ibaraki uses all three junior-high years (grade 1, grade 2, and grade 3): the nine subjects (kokugo, social studies, mathematics, science, English, music, art, health and physical education, and technology and home economics) are each rated on a 5-point scale, giving 9 × 5 = 45 points per year and 45 × 3 years = 135 points total. In the common selection the 500-point academic test and this 135-point report card are weighted roughly equally, with the specific conversion ratio set by each school.
What is the Reiwa 8 (2026) application and results schedule?
Web application (shigansha jōhō nyūryoku) ran January 7–28, 2026, with paper application acceptance February 5–9, 2026 and application-change (shigan-saki henkō) on February 10 and 12, 2026. The JPY 2,200 fee was paid with Ibaraki prefectural revenue stamps or electronic settlement. The academic examination was held on February 26, 2026 (Thursday), with selection results announced on March 11, 2026 (Wednesday) at 9:00; the makeup examination (tsuiken) was March 4–5, 2026 and second recruitment (dai-ni boshū) application March 12–13, 2026.
What is the common selection (kyōtsū senbatsu) two-stage process?
In the common selection, applicants who did not pass the special selection (tokushoku senbatsu) and those who applied only to the common selection are judged in a two-stage process: the A-group selection (A-gun senbatsu) uses a both-rank duplication method (ryō jun'i chōfuku hōshiki) that lets applicants list a first and a second-choice school, and the B-group selection (B-gun senbatsu) follows for remaining places. The specific conversion ratio of the test and report card is set by each school.
What parts of the junior-high mathematics curriculum does the exam cover?
The paper covers the 2017 MEXT junior-high mathematics curriculum in six major questions: numbers and expressions (including square roots), linear/simultaneous/quadratic equations and inequalities, proportional/linear/quadratic functions, plane geometry with proofs and the Pythagorean theorem, solid geometry and measurement, and data analysis with probability. This bank distributes its 100 items across those six strands.
Do these details apply to the next (Reiwa 9 / 2027) entrance examination?
Most figures on this page describe the Reiwa 8 cycle, whose academic examination was sat on February 26, 2026. For the Reiwa 9 (2027 entrance) cycle, the Board has published the schedule: academic examination on February 25, 2027 (Thursday) with results March 11, 2027 (Thursday). The five-subject, 50-minute, 100-point structure and the report-card-plus-test selection method have been stable, but confirm the current year's application windows, fees, and selection ratios on the Ibaraki Prefectural Board of Education's own pages before relying on them.
