At a time when the fate of a U.S. Marines' Futenma base in Okinawa is dominating headlines, a documentary is shedding light on the troops and the training they undertake before living on foreign soil.

Director Yukihisa Fujimoto went to South Carolina's Parris Island, one of the marines' main training facilities, to document the 12-week process used to convert pimply boys and girls into fighting men and women in "One Shot One Kill," now screening in Tokyo.

Fujimoto, a critic of the many U.S. military facilities in Japan, including the Futenma air station, said he was motivated to shoot the film after spotting young marines in Okinawa and realizing he knew little about them and who they were before being deployed to Japan.
