Movies like Searing Wind (1943)

Set in wartime at the Yawata Steel Works in Tobata, Yawata, and Kokura cities in Fukuoka Prefecture, the film depicts people taking on the evil blast furnaces that prevent increased production. The film was shot on location at the actual Yawata Steel Works for an extended period of time, and special effects were created using a miniature blast furnace that closely reproduces the actual one.
