I think memory is the most important asset of human beings. It's a kind of fuel; it burns and it warms you. My memory is like a chest: There are so many drawers in that chest, and when I want to be a fifteen-year-old boy, I open up a certain drawer and I find the scenery I saw when I was a boy in Kobe. I can smell the air, and I can touch the ground, and I can see the green of the trees. That's why I want to write a book.
