Issey Miyake in the Times. Interesting the explicit reference to optimism, which is both the strength and limitation of design. The richness of his work originates less in optimism than an ongoing effort to justify it. The difference between Fra Angelico and Velazquez: between faith and the desire for faith: a noble lie.

On Aug. 6, 1945, the first atomic bomb was dropped on my hometown, Hiroshima. I was there, and only 7 years old. When I close my eyes, I still see things no one should ever experience: a bright red light, the black cloud soon after, people running in every direction trying desperately to escape I remember it all. Within three years, my mother died from radiation exposure.

I have never chosen to share my memories or thoughts of that day. I have tried, albeit unsuccessfully, to put them behind me, preferring to think of things that can be created, not destroyed, and that bring beauty and joy. I gravitated toward the field of clothing design, partly because it is a creative format that is modern and optimistic.

I tried never to be defined by my past. I did not want to be labeled “the designer who survived the atomic bomb,” and therefore I have always avoided questions about Hiroshima. They made me uncomfortable.

But now I realize it is a subject that must be discussed if we are ever to rid the world of nuclear weapons. There is a movement in Hiroshima to invite Mr. Obama to Universal Peace Day on Aug. 6 the annual commemoration of that fateful day. I hope he will accept. My wish is motivated by a desire not to dwell on the past, but rather to give a sign to the world that the American president’s goal is to work to eliminate nuclear wars in the future.
