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.

Slum remains a visceral critique of social erasure and a vital, observational work of Japanese documentary film.
