🟥Waseda Junior High vs. 🟦Kaijo Junior High | 2027 Entrance Exams: Which School Is Right for Your Child?

The representative of Shin-Juku discusses the realistic admission strategies for Waseda and Kaijo

“Even within the same deviation score range, the required skills are vastly different.”

Waseda Junior High School and Kaijo Junior High School. Both are leading boys' preparatory schools in the Tokyo metropolitan area, and many examinees compare them. For the 2027 academic year, both schools will hold entrance exams on February 1st and February 3rd. Both use a four-subject exam format (Japanese, Math, Social Studies, and Science), and looking at the subject weightings alone, they are identical: Japanese 30%, Math 30%, Science 20%, and Social Studies 20%.

However, even with the same subject weightings, the exam duration, point distribution, volume of information in the questions, answer formats, and methods for accumulating points differ significantly. Waseda emphasizes the ability to accurately collect the points you should get within a limited time. On the other hand, Kaijo emphasizes the ability to organize long texts and multiple conditions or materials, and to construct final answers, multiple-choice selections, and written responses.

Waseda is a “precision collection type” that accurately and rapidly captures core subject areas⚡. Kaijo is a “structural completion type” that structures complex conditions and materials to build up points through complete answers and written responses🧠.——Even among top-tier boys' schools, the strategies for success are completely different.

This article is not intended to compare which school, Waseda or Kaijo, is more difficult. It is an article to help you judge “which school is easier for my child to improve their score in” for 2027, by deciphering the reasons why compatibility with past exam questions differs so much despite the same deviation score range, same exam dates, and same subject weightings, based on the 2026 entrance exam results and the question trends for each subject.

In this article, rather than just introducing the schools, we will delve into the answer-writing behaviors that bring you closer to passing both Waseda and Kaijo, based on the 2026 entrance exam results and question trends up to 2026. In the paid section in particular, we will organize details for each subject, including “which units are likely to appear,” “in what form those units appear,” “why there is a difference in past exam scores despite the same subject weightings,” “what the differences are between Waseda-style and Kaijo-style answer-writing behaviors,” and “what you should check in past exam questions for 2027.”

“Between Waseda and Kaijo, which is my child better suited for?” “Why is there a difference in past exam scores even though their mock exam deviation scores are similar?” “If they are good at math, which school allows them to demonstrate their strengths more easily?” “Is there a way to pass even if they have weak subjects in Japanese or Science?” “What should be prioritized in the remaining time for 2027?”—This content is for those who have such questions.

In this article, we will clarify the subjects that actually determined pass/fail in the 2026 entrance exams, the trends for each subject visible from past exam questions up to 2026, the differences in the skills required by Waseda and Kaijo, the measures that should be prioritized for 2027, and the types of examinees suited for each school.
