This paper aims to understand Japan's colonial responsibility post–war and present a new picture of '1968'. It examines incidents of ethnic discrimination excluded from the university–centered narrative, focusing on three late 1960s cases – the Kim Hee–ro incident, Li Zicheng's suicide, and Kaseitō's accusations – to address ethnic discrimination against Zainichi Koreans and Chinese. First, in February 1968, the Kim Hee–ro case unfolded at Sumatakyō Onsen inn, a hostage situation denouncing police racism. Suzuki Michihiko, a Japanese intellectual, leveraged his connection with Kim Hee–ro to discuss Japanese imperialism's war responsibility and racism. Yazaki Kaoru, a Nichidai Zenkyōtō viewed Kim's action as a struggle practice rather than intrinsic ethnic discrimination. Next, Li Zicheng's suicide, a Taiwanese student, was triggered by the Immigration Control Act issue. Neglected by the New Left movement, fear of deportation intensified, leading to Li's death and a rift with Kaseitō. Student activist Tsumura Takashi adopted a self–reflective approach, seeking to amend the struggle's strategy and direction. The New Left's self–critique and Zenkyō'tō's shift altered student movement goals, emphasizing the importance of ethnic discrimination issues. This redirection moves away from the '1968' narrative steeped in 'Showa Nostalgia', guiding towards recognizing Zainichi's structural discrimination and the colonial issue.
