A male broadcaster asked Mr. Nagano, "Please tell me how you felt when you pushed the button".

He answered, "I was just surprised. Really surprised. Only that".

Then the broadcaster asked next, "What did you find at the goal?"

Mr. Nagano answered, "Many people have asked me about
that time and again. And I've thought of telling the truth when I stand
here (meaning at the top of the tower after clearing the course). To
tell the truth, there is nothing here for me. I just like Sasuke. And by
doing Sasuke.... my fellows, friends,...  To have the opportunity to
stand here, on the stage of Sasuke, with them. Yes... You know..."

Then,he brushes the tears with his hand.

Then the male broadcaster asks him again, saying, "What does Sasuke mean to you?"

He answers, "Hmm, I can't say... You know, it's like a place where I can leave a sign that I have lived. But most of all, ... really, you know, it's friends... I really enjoy doing this with them. It's really just that that motivates me..."
