Picture that my dad apparently took of Japanese General Masaharu Homma. The back of the picture says: “Jap General Homma and aides taken Naha Air Field.” Another similar photo continues with: “...on way to Manila to be tried for war crimes.”
According to Wikipedia, Gen. Homma was military commander of the Philippines. During the Japanese occupation, the Bataan Death March occurred and civilians were brutalized. The Japanese military, however, thought he was too cautious and too lenient with Philippine civilians and forced him into retirement in August 1943.
After the war ended, he was captured and transferred to Manila to stand trial for war crimes. He was convicted and executed on April 3, 1946.
This photo was apparently taken during a layover in Okinawa on the way to Manila. Since he was retired, that would explain why he is not wearing a military uniform.
Also according to Wikipedia, there is a film adaption in the works about the general called Beast of Bataan. Actor Hayden Christensen is attached to the project.
