After the 60th anniversary of the atomic bombings of Hiroshima and Nagasaki passed last August, filmmaker Steven Okazaki began worrying that the attacks and their cautionary lessons are being forgotten.

"If you really ask young people, they know very little about Hiroshima and Nagasaki," the 54-year-old Japanese-American said. "I think that's very disturbing."

While doing research recently for his upcoming film, the Oscar-winning filmmaker asked young people in Tokyo's trendy Harajuku district about the significance of Aug. 6, 1945.
