It is an adaptation of the novel The Sun of Kurobe (é»Âé¨ã®太é½; Kurobe no Taiyà Â) that dramatizes the construction of the massive Kurobe Dam, the tallest dam in Japan. The film was Japan's submission to the 41st Academy Awards for the Academy Award for Best Foreign Language Film, but was not accepted as a nominee. Produced by its stars Toshiro Mifune and Yujiro Ishihara, the film's first run in cinemas lasted for a month, significantly longer than the week or ten days that films at that time usually ran in Japan.
