Yes, it was a great honor to lead the project. But though my role was project leader, if I had to put my finger on what precisely I did, I'd say that I lit the touch paper for the project. Once development got properly under way, I think it would be fair to say that I was basically just watching from the sidelines. At the point where we were just about to start mass production, Yoneyama-san had already been working extremely hard for a long period over in China. If he had been a younger colleague, I could have said something like: "Go for it! Just one more push!" But with a senior colleague with as much more experience as Yoneyama, I was rather a little concerned about his health!
