K-kai (Bunkyo-ku, Tokyo), a place to learn advanced mathematics and science within the Kawaijuku Group, celebrates its 30th anniversary this year. As part of the 30th-anniversary events, a special seminar introducing the world of "unsolved mathematical problems" will be held on Saturday, April 11, for junior and senior high school students who love mathematics. The speaker is Mr. Junnosuke Koizumi, a Special Postdoctoral Researcher at RIKEN and a K-kai alumnus.
■ Discover the Joy of Pursuing Questions No One Knows the Answers To
Since its opening in 1996, K-kai has offered programs for top-level junior and senior high school students that do not set passing entrance exams as the goal, nor are they bound by grade levels or subjects. Instead, they provide opportunities to learn advanced mathematics and science "enjoyably," "deeply," and "as much as you want to learn." Over its 30-year history, many researchers who discovered the joy and depth of learning here have emerged from its alumni and are currently active in their fields.
Mr. Junnosuke Koizumi, who will be speaking this time, is one of them. He became interested in physics and mathematics during high school and encountered modern mathematics at K-kai. After that, he deepened his studies at the University of Tokyo and its graduate school, and is now an up-and-coming researcher studying algebraic geometry and arithmetic geometry at RIKEN.
Mr. Koizumi will talk about "Unsolved Problems in Mathematics." He will introduce "unsolved problems," which are rarely handled in school learning, starting from familiar "plane figures." Questions close to junior and senior high school students, such as the arrangement of triangles and quadrilaterals, distances between points, angles, and areas, lead to surprisingly deep and difficult problems—through this unexpectedness, he will convey the depth of mathematics and the joy and thrill of pursuing questions to which no one knows the answers.
As Japan's decline in research capabilities and the shortage of science personnel are being reported, K-kai's initiative serves as an opportunity for junior and senior high school students to broaden their perspectives and their own possibilities by learning the inherent fascination and meaning of academia.
Please share this valuable opportunity through your media. We also welcome press coverage.

[About K-kai] ~A learning environment full of intellectual stimulation where many Math Olympiad participants gather~
This is a course specialized in learning mathematics, information science, and physics "at a higher and deeper level" as "academic disciplines," rather than with the ultimate goal of passing entrance exams. It breaks down the barriers between junior high school, high school, and university to realize systematic, deep learning. Instructors are mainly current students and alumni of the University of Tokyo and its graduate school, and International Science Olympiad medalists also teach classes. In 2023, two alumni, and in 2025, one alumnus participated in the International Mathematical Olympiad and won gold medals. In addition to regular classes, Math Olympiad-related courses are also held to convey the depth and appeal of academia. ◆K-kai Website https://www.kawai-juku.ac.jp/kkai/
