🔑 The 'Core of Showagakuin Shuei Entrance Exams' revealed by analysis

These are the common characteristics of Showagakuin Shuei Junior High School entrance exams that have emerged from the analysis.

1. Arithmetic consists of 5 large questions, all of which are descriptive. Solid geometry (plane + solid) accounts for an overwhelming 40-45% of all questions, and regularity and properties of numbers are required every year, showing a trend of increasing difficulty.
The structure of 5 large questions, all descriptive, is fixed, and solid geometry-related problems are presented at an overwhelmingly high ratio of 40-45% of all questions compared to other schools. Multiple questions from both plane geometry and solid geometry are presented every year. Regularity and properties of numbers are also required every year, and there is a trend that the difficulty level is increasing year by year.

2. Social studies uses 'reading long lead passages' as the entry point for all large questions. A specific regional theme has been presented for 3 consecutive years (Iwate -> Hokkaido -> Niigata). Character-count-specified descriptions (20-70 characters) and true/false combination selections appear as a set every year.
All large questions include long lead passages, and the style of answering questions after reading the lead passage is fixed. Comprehensive problems focusing on specific regions have been presented for three consecutive years (2024: Iwate Prefecture, 2025: Hokkaido, 2026: Niigata Prefecture), asking about the geography, history, industry, and culture of those regions in an interdisciplinary manner. Character-count-specified descriptions and true/false combination selections appear as a set every year.

3. Science has an overwhelming majority of descriptive questions (3-year average of 64%). Physics, chemistry, and biology are required for 3 consecutive years. Experimental observation and calculation are the two pillars, and puzzle-like problems are presented in physics every year.
The ratio of descriptive questions in science maintains a remarkably high level for a difficult school, with a 3-year average of 64%. Physics, chemistry, and biology have been presented as large questions for three consecutive years (earth science appears every year, but may not be independent as a field), and both experimental observation and calculation are asked throughout all large questions. In physics, problems that require 'assembling mechanisms like a puzzle to answer' are presented every year.

🔢 Arithmetic | 5 large questions, all descriptive. Solid geometry accounts for 40-45% of all questions; regularity and properties of numbers are required every year, showing a trend of increasing difficulty.

Characteristics of consecutive questions

• 5 large questions, all descriptive (zero multiple-choice) is fixed.

• Solid geometry is presented at a high ratio of 40-45% of all questions.

  • Both plane geometry (area ratio, angles, similarity, equal-area transformation) and solid geometry (cutting, volume, surface area, solids of revolution).

  • 2024: 2 plane questions + 2 solid questions (total 4 questions related to geometry).

  • 2025: 2 plane questions + 2 solid questions + 1 spatial awareness question.

  • 2026: 2 plane questions + 3 solid questions (solid ratio increased).

• Regularity and properties of numbers are required every year (trend of increasing difficulty).

  • 2024: Rules of sequences and general terms.

  • 2025: Enumeration of integers with conditions and discovery of rules.

  • 2026: Properties of numbers with complex operational rules (difficulty level increased significantly).

• Ratio and proportion (saltwater, speed, work problems) appear every year.

Points for 2027
Since solid geometry accounts for more than 40% of all questions, completing plane geometry and solid geometry to the same level is an absolute condition for passing. For solid cutting, establish the habit now of confirming 'which face is cut and what the shape of the cross-section is' while drawing it into the solid diagram. Since regularity continues to show a trend of increasing difficulty, repeat the practice of visualizing the 3-step solution process in your notebook: 'first try with small numbers -> discover the rule -> generalize'. Because all questions are descriptive, make it a habit to practice writing 'explanations that combine formulas and words' for all problems.

🌍 Social Studies | Long reading passages serve as the entry point for all major questions; specific regional themes for 3 consecutive years (Iwate → Hokkaido → Niigata); character-count-specified descriptive questions and true/false combinations appear every year

Characteristics of consecutive questions

• Long reading passages accompany all major questions (a fixed style of answering questions while reading the passage)

• Comprehensive questions focusing on specific regions have appeared for 3 consecutive years

  • 2024: Iwate Prefecture (Agriculture, forestry and fisheries, traditional culture, reconstruction from the Great East Japan Earthquake)

  • 2025: Hokkaido (Agriculture, dairy farming, history of development, Ainu culture, tourism)

  • 2026: Niigata Prefecture (Rice cultivation, heavy snowfall areas, Sea of Japan climate, historical trade)

• Descriptive questions with character limits (20–70 characters) appear every year

• True/false combination selection (format: "Select the correct combination") appears every year

• Complex questions that span geography, history, and civics are incorporated into each major question

Points for 2027
As a countermeasure for specific regional questions, the most reliable preparation is to maintain a notebook organized by the 7 axes of "climate, topography, agriculture, industry, transportation, culture, and history" for all 47 prefectures in Japan. The ability to explain regional characteristics, regardless of which region is featured, will determine success or failure. For descriptive questions with character limits, practice adjusting the amount of information according to the length: "20 characters → facts only," "40 characters → facts + reasons," and "60–70 characters → facts + reasons + impact." For true/false combination questions, the only way to increase your correct answer rate is to thoroughly follow the procedure of "checking the truth of each item before selecting the combination" and leaving no ambiguous knowledge behind.

🔬 Science | Descriptive questions average 64% over 3 years; Physics, Chemistry, and Biology are mandatory for 3 consecutive years; experimental analysis and calculations are the two pillars; puzzle-like problems in Physics

Characteristics of consecutive questions

• Descriptive questions average 64% over 3 years (an exceptionally high level for a top-tier school)

• Physics, Chemistry, and Biology have been mandatory as major questions for 3 consecutive years

  • Earth science appears every year but may not always be an independent major question

• Experimental analysis and calculations appear as the two pillars throughout all major questions

• Physics puzzle-style problems (problems requiring the assembly of mechanisms and logical reasoning) appear every year

  • 2024: Compound problem on levers and centers of gravity (considering equilibrium while changing conditions)

  • 2025: Combinations of electrical circuits and the relationship between current and voltage (circuit puzzles)

  • 2026: Compound problem on buoyancy and density (reasoning about combinations of liquids and floating/sinking)

• Descriptive questions asking to "explain the experimental procedure" appear every year

• Compound problems combining graph reading and numerical calculation appear every year

Key points for 2027
To handle the 64% descriptive question rate, practice three-stage causal descriptions—"experimental results → why it happens → what laws are at work"—daily across all fields. For physics puzzle problems, it is effective to train your variable manipulation thinking by asking, "If I change one condition, what changes?" Master the three themes of levers, buoyancy, and electrical circuits in three stages: "basic calculation → condition changes → compound problems." Focus on practicing how to carefully break down and solve chemistry calculations (solubility, neutralization, gas volume), and minimizing point losses in biology and earth science knowledge questions is the key to stabilizing your total score.
