Anti-discrimination student uprisings (known as “Issei Kyudan Toso”) arose in the late 1960s and early 1970s in several Japanese high schools in the Hanshin (Osaka-Kobe) area. Encouraged by the rapid rise of the Buraku liberation movement in the 1960s, Korean students attending Japanese high schools in the Hanshin area, who had passed as Japanese by using Japanese-style names began to identify as Koreans by using their real (ethnic) names. They established themselves as ethnic subjects who fought against discrimination in Japanese society and severely criticized Japanese teachers for turning a blind eye to the discrimination they faced and were victims of. This study reveals how identity politics functioned in this process by analyzing a recent novel titled “Bokura no Hanran (Our Rebellion),” written by a second-generation Zainichi Korean writer, Bang Jeongung. Bang was one of the leading activists of the student uprising, later became a high school teacher, and wrote a novel based on his own experiences after retirement. Bang’s novel provides valuable insight into how Korean students at Japanese high schools in the Hanshin area experienced the anti-discrimination movement in the late 1960s, when it was om the rise. From today’s perspective, the ethnic identity constructed in this movement seems to be too monolithic, even suppressive of each individual’s intersectionality; however, Bang’s novel depicts a strong enough momentum of this movement at its inception point to make participants focus on ethnic identity.
