Zoom-Up Math by Z-kai future success in STEM!!

Our Philosophy

Z-kai will continue to contribute to social innovation and progress through our educational services, developing the skills and competencies needed to create future global leaders.

Our History

Z-kai offers educational services in Japan from its inception in 1931, particularly focused on developing challenging material for advanced and gifted preK-12 students.
In the past forty years, over 1/3 of the students who passed the entrance examination to the University of Tokyo, which is the most competitive higher education institution in Japan, have made use of our services to achieve their success.

Through experiences serving more than 200,000 Japanese students each year, Z-kai has learned that it is better for students to solve a limited number of well-thought-out problems rather than numerous less-challenging ones. In this way, students’ mathematical knowledge, thinking skills, and processing are maximized and made more flexible. We will contribute to raising mathematics educational standards not only in Japan but also in the United States by offering our world leading quality materials.
