'[Rüdiger Tomczak] I remember an interview I had with Kumai in the year 1995 during the Montreal World Film Festival...During this interview Kumai told us that he had to work as an adolescent with Korean Forced laborers at an airport where Kamikaze pilots were starting. As an adolescent he witnessed discrimination of non-Japanese during that time. Kumai was too young for being responsible for the Japanese terror but too sensitive to be able to forget the dark chapter of Japanese civilization. But he was old enough to get an idea about the dark sides of human beings during the war.'
