Our aim is to foster global citizens who understand Japan through Japanese language education, who can become a bridge between Japan and their home countries, contribute to the development of the international community, and support Japanese deaf education and language development for children.

Ezoe Canel Ryuji, Chairman of the Board
Shinjuku Japanese Language Institute was founded in 1975 by my grandparents and father. At that time, Japanese language education was still largely unfamiliar, and many learners came from Western countries. For that reason, English was commonly used to explain Japanese grammar in class.
However, from the 1980s onward, the number of students from Asia increased rapidly, and it became difficult to fully meet their needs with English-based materials made for Western learners. In response, my father began closely observing students’ learning processes and devoted himself to developing original teaching methods and materials. Through continuous improvement, “Ezoe Grammar,” which later became the core of our school’s education, was born.
Using colors and visual charts to show parts of speech, breaking Japanese sentences into “Information” and “Predicate,” and understanding particles through a two-tier structure—these and many other innovations established a systematic and intuitive approach to learning Japanese.
The visual grammar system has also been recognized as effective not only for foreign learners, but for students who are deaf and acquiring written Japanese. Today, we are also putting effort into applying it to deaf education.
With this background, our aim is:
And guided by the principle:
We strive not merely to teach the language, but to explore the very substance of education itself—through research on Japanese grammar and kanji instruction, as well as analysis and study of Japanese language education. Our goal is to deliver an education through which each learner can achieve their target outcomes.
Furthermore, by continuing to develop and refine our grammar and teaching materials, we strongly believe we can contribute meaningfully to the field of Japanese language education.
We will continue learning and growing, and together with all of you, expand the possibilities of Japanese education.
