Caterpillar (キャタピラー, Kyatapirā) is a 2010 Japanese drama film directed by Kōji Wakamatsu, partially drawn from Edogawa Rampo's banned short-story "The Caterpillar" (芋虫, Imomushi, 1929).
The film is a critique of the right-wing militarist nationalism that guided Japan's conduct in Asia during the Second Sino-Japanese War and World War II. The film deals with various issues, such as war crimes, handicapped veterans, and spousal abuse. The film also deals with themes of sexual perversion and features graphic sex scenes.
It was nominated for the Golden Bear at the 60th Berlin International Film Festival. Shinobu Terajima received the Silver Bear for Best Actress at the Berlin Film Festival for her portrayal of Kurokawa's wife.
