When the Red Army invaded Manchukuo, they captured 850,000 Japanese settlers. With the exception of some civil servants and soldiers, these were repatriated to Japan in 1946–7. Many Japanese orphans in China were left behind in the confusion by the Japanese government and were adopted by Chinese families. Many, however, integrated well into Chinese society. In the 1980s Japan began to organize a repatriation program for them but not all chose to go back to Japan.
