Sayama incident
The Sayama incident (狭山事件, Sayama Jiken) occurred on May 1, 1963, when 16-year-old Yoshie Nakata was kidnapped, raped, and murdered by an unconfirmed individual in Sayama, Saitama, Japan. The incident, in which then-24-year-old Kazuo Ishikawa, a man of disputed guilt in the case, was imprisoned for 31 years, highlighted official discrimination against Japan's burakumin caste.
