M (30 years old) who faces deportation on charges of overstaying, is currently (as of the end of August, 2018) incarcerated at the East Japan Immigration Center, located in Ushiku city, Ibaraki prefecture. He is a Nikkei who was a 10-year-old pupil at his arrival in Japan. Shortly after entering junior high school, he stopped attending classes, and ended up getting involved repeatedly in delinquent and criminal acts. While in prison, he lost his status of long-term resident, and became an illegal immigrant. Regarding the disposition of his case, he objected it by filing an appeal against the court’s decision, but he lost the lawsuit appeal in a district court and a high court. As well as M, not a few non-Japanese pupils in Japan are also being denied the opportunity for an education and have to go through similar experience. This paper presents and analyzes M’s life in Japan, where he has been living for almost 20 years, and aims to identify the issues and circumstances that surround non-Japanese pupils and illegal immigrants.
