My Marine dad was on the invasion fleet at sea headed to Japan when the bombs dropped. He then became part of the occupation force. All I know of his time there were two souvenirs he brought home: a Japanese Rising Sun flag and a silk parachute to make Mom’s wedding dress for October 1947. I sure wish he had kept a diary and that I had talked to him about his experiences in Japan. He didn’t bring home any love for Japan and we sure didn’t adopt any Japanese culture in our home.
My dad was in Tokyo Bay for the surrender and was part of the initial occupation forces. He hated the Japanese until the day he died.
