I happened across the story of Takejiro Higa on the University of Hawaii web site. He was born in Hawaii of Okinawan ancestry, moved to Okinawa at 2 years of age and returned to Hawaii at 16. He witnessed the attack on Pearl Harbor and enlisted to serve in US Army Military Intelligence Service. His service returned him to Okinawa to participate in the battle as an interrogator and translator. A fascinating life.
