Tadashi Imai
After Japan's defeat in World War II, Iwasaki was active in criticizing those who participated in the war effort. He joined Nihon Eigasha (Nichiei), primarily a documentary film company, and helped produce two important, but ill-fated documentaries: "The Effects of the Atomic Bomb on Hiroshima and Nagasaki", which was confiscated by Occupation authorities, and "A Japanese Tragedy", directed by Fumio Kamei, which was banned for its critical depiction of Emperor Hirohito. While continuing to work as a film critic from the 1950s on, including pursuing a vigorous debate on the nature of cinematic realism with Taihei Imamura, Iwasaki helped produce some of the independent films made by Tadashi Imai and Satsuo Yamamoto after many left-wingers were expelled from the major studios in the Red Purge.
