Two of the largest minority groups in modern Japan--Koreans, who emigrated to the metropole as colonial subjects, and a social minority known as the Burakumin, who descended from former outcastes--share a history of discrimination and marginalization that spans the decades of the nation's modern transformation, from the relatively liberal decade of the 1920s, through the militarism and nationalism of the 1930s, to the empire's demise in 1945.
