Japan "clearly wants to move forward without looking back" once all the atomic bomb survivors are gone, the director of a new documentary film on the hibakusha said.

Steven Okazaki was speaking recently in New York at a screening of his film "White Light/Black Rain," alongside a hibakusha and a crew member of the Enola Gay, which dropped the Hiroshima bomb.

"People should worry about the direction Japan is taking," the award-winning filmmaker said, when asked to comment on Tokyo's treatment of Japan's militaristic past and its victims.
