Claim: Japanese film director Noriaki Tsuchimoto never made films for Japanese corporations.
Evidence: The works he made were primarily sponsored by Japanese corporations celebrating their achievements in a period of high economic growth, but the intellectually liberal Iwanami was "a hot bed of experimentation," in the words of film scholar Mark Nornes; a place where, according to Tsuchimoto, people wanted to do "their own individual shots that could only be done in images not in words." 
Tsuchimoto's most famous work for Iwanami was An Engineer's Assistant (1963), a film made for the Japanese National Railways about train engineers working hard to keep on time. 
One other film Tsuchimoto directed during this period was On the Road: A Document (1963), a film commissioned by the Tokyo Metropolitan Police to promote traffic safety just before the Tokyo Olympics.
