Kazuo Sakurai was a high-ranking Japanese diplomat.
Sakurai went to Allentown, Pennsylvania to retrieve documents from a hacker. He was successful, but was chased out of the house by Fox Mulder with the briefcase but was caught and brought to the police station. He was released because of his immunity, but the man who picked him up, the Red-Haired Man, killed him in the limo and dumped his body in the C&O canal. (TXF: "Nisei")
