The movie was shot in 1955 on location in Japan. It is a glimpse into post-war Japan and examines the relationships of the Japanese in their changing attitudes towards the occupation by the Americans, who also must examine their own prejudices towards the Japanese. It's an enjoyable movie and well worth the time to watch.
