Authors' Note:
[1] Allied occupation forces were responsible for the return of six million Japanese military personnel and civilians from Japan's defunct far-flung Empire. In addition, there were over a million Korean and about 40,000 Chinese prisoners and conscript laborers and approximately 7,000 Formosans and 15,000 Ryukyu Islanders to be repatriated.

Some Allied and many former IJN warships, from aircraft carriers to kaibokan, were used to facilitate the enormous repatriation effort. Japanese vessels and crews were used to the fullest extent possible to conserve Allied manpower and accelerate demobilization. Each ex-IJN ship first had to be demilitarized; guns removed or, in the case of large warships, barrels severed, ammunition landed, and radar and catapults removed, if fitted. Repatriation of the Chinese on Japanese ships began early in October from Hakata, but U.S. guard detachments had to be placed on many ships to prevent disorder because the Japanese crews could not control the returnees.

Japanese-run repatriation centers were established at Kagoshima, Hario near Sasebo, and Hakata near Fukuoka. Other reception centers were established and operated at Maizuru, Shimonoseki, Sasebo, Senzaki, Kure, Uraga, Yokohama, Moji and Hakodate. Allied line and medical personnel supervised the centers. Incoming Japanese were sprayed with DDT, examined and inoculated for typhus and smallpox, provided with food, and transported to his final destination in Japan.

Thanks go to Dr. Higuchi Tatsuhiro of Japan, Mr Jeff Donahoo of Iowa, USA and Mr. Gilbert Casse of France.
