Unlike other western countries of immigrants, Japan is a non-immigrant country, and the education of public junior and elementary school education in Japan is considered to be essentially Japanese assimilation education. We have been teaching Japanese language learning to foreign-rooted students in Japanese public elementary and junior high schools for many years, and have to face those problems such as loss of mother tongue, school maladjustment, and decline in academic ability on a daily basis. In order to solve these problems more smoothly, We founded U Academy. From the perspective of bilingual education, we will improve students' Japanese cognitive ability and at the same time solve problems that school counselors failed. I would like to contribute to the stability and prosperity of Japanese society by continuing to solve these problems.
