While directing his war movie "Siege of Fort Bismarck" (1963), he insisted that "special effects are not used because they are not powerful!" , the director of special effects, told him to try it without special effects, and he started shooting only with Furusawa, but in the end, Kengo apologized to Tsuburaya. After that, when he saw the result of the special effects, he prostrated, "It's Tsuburaya after all." From the standpoint of disagreeing with the Tokyo Tribunal, he continued to submit plans for "Asia no Arashi," which depicts the modern history of Japan, to Toho, but it was not realized due to Toho's corporate culture, which dislikes political topics. Kengo loved the "red color of the Hinomaru", so I was particular about the color of the title of my movie, and even rushed to the photo lab to make it a convincing "red color of the Hinomaru".
