Originally commissioned to record urban redevelopment in Osaka’s Kamagasaki district, Hideo Arai transcends reportage to capture a haunting portrait of displacement during Japan’s economic miracle. With a dissonant score by experimental composers Toshi Ichiyanagi and Yuji Takahashi, the film juxtaposes the brutal reality of shantytown "barracks" against the state's modernization projects. Slum remains a visceral critique of social erasure and a vital, observational work of Japanese documentary film.
