Jōhatsu, literally “evaporation” is the Japanese term for people disappearing without a trace. Salesman Tadashi Oshima is one of them. Director Shōhei Imamura, together with Oshima's fiancé Yoshie Hayakawa and actor Shigeru Tsuyuguchi created an investigative documentary that looks into this man, his motives, his possible whereabouts, and the others that are gone.

 

人間蒸発 is a fascinating exploration of aspects of 1960s Japanese society that make jōhatsu distinct from similar phenomena elsewhere.
