School Outline

Educational Philosophy

True freedom nurtures the will and strength to grow independently.

Josai has three founding principals; extension of natural aptitude, respect for individuality, and respect for individual ingenuity. This is all enveloped within the philosophy of “ho’on kansha”, or “returning kindness with gratitude”. There is an environment in which students’ talents, academic abilities, and other core parts of education are developed. We consider the relationship of teachers and students as well as that between students when considering class organization. While respecting individuality, we foster the abilities for our students to be contributing members of society during their time at Josai.

Fostering the “ability to get involved” through the accumulation of experience
Education to create human resources who will survive in the world of the future

Our school motto is “ho‘on kansha“, which means to be grateful for everything that surrounds us, the environment, the earth, and nature, and to repay them for their kindness. In order to repay these favors, it is important to lead a happy life. In order to lead a happy life, it is necessary to make unremitting efforts in junior high and high school. Through study, club activity, and school events provided by our school, students will be able to recognize their own self-worth, and to recognize the value of their own existence and that of others. The repetition of these activities will lead to “self-confidence” and “self-affirmation. School is a place of training and discipline where students can develop their character through these activities. The experience, knowledge, and skills gained through such training become one’s own assets. Young people who acquire these assets will feel a great sense of personal growth, will be grateful to those around them, and will try to “repay” them for their kindness. In time, the scope of their attempts to “repay” will expand to the town, the country, and the world in a large circle.

In 2018, our school started a new integrated junior and senior high school education program, “JOSAI Future Global Leader Program” (JFGLP). The JFGLP has steadily produced positive results by fusing in-school and out-of-school learning with hands-on experience to cultivate independence, problem-solving skills, and a global perspective, with the goal of nurturing individuals who will be active in society and in the world in the future. The JFGLP also emphasizes career education that looks beyond the university entrance examination as its goal, and cultivates the ability of each student to approach university entrance examinations with a clear idea of “where and what I want to study for my future self”.

At the same time, our school is committed to not only capturing students’ growth and achievements through the senses, but also data on the effectiveness of education. While adapting to the trends of the times and changes in the world, we will provide support tailored to the growth of each individual student, utilizing the flexibility and quick decision-making ability that only a private school can offer. In order to provide appropriate support, teachers must also be willing to learn. We will continue to challenge new initiatives, remembering that we will learn together with our students and that our faculty members will continue to grow as well. We will continue to focus on education that nurtures goal-oriented, independent individuals while maintaining the liberal education and warm school culture that have taken root in our school and keeping a close eye on trends and fashions. Please look forward to the new initiative at Josai.
