Kawate Haruo knew that his father, Masao, a second-generation Japanese American, returned to Japan after World War II. That, however, was about all he knew of it. After Masao's death, Haruo found a letter to an American attorney, Wayne Collins, seeking restoration of his American citizenship.

Follow along as Haruo pieces together the facts of his father's life, 80 years after the attack on Pearl Harbor.
