  1. Q1. What was your most impressive work?
    We faced many difficulties when the film I developed was put through a small quantity prototype maker carried only by E.I. du Pont de Nemours and Company (commonly known as DuPont) in the United States for film-formatting test, but after the film was rolled up, the local operators cheered joyfully with me, which was a great memory.
  2. Q2. What does your company do?
    The company manufactures and sells three high performance products: Kapton® polyimide film, Hytrel® polyester elastomer, and Kevlar® para-amid fiber[1].
  3. Q3. What does your department/section do and what work are you in charge of?
    Our group develops polymer for new polyimide film and looks for their new applications. I am responsible for the polymer development group as a group leader.
  4. Q4. What kind of job do you mainly put a lot of effort into?
    I cannot write the details but I focus my effort into developing new polymer and elemental technology that could become "The new foundation to stand on."
  5. Q5. When do you feel rewarded at work?
    I feel great joy when a new product take shape using the technology established through past failures and successes with the cooperation of colleagues from other departments.
  6. Q6. What is it that you put a lot of effort into in your personal life?
    It’s watching my two sons play in soccer games and playing futsal with a team composed of mostly friends from my neighborhood. Although I’m not an experienced soccer player, I work hard to learn how to play with my sons teaching me.
    Also, because my home is close to the airport and many foreigners live around the neighborhood, I enjoy international exchange through playing futsal.
