During the Second Sino-Japanese War, the Japanese government introduced a plan to settle 5 million Japanese in Manchukuo. Following the end of the war, approximately 2,800 Japanese orphans in China were left behind by families repatriating back to Japan. The majority of Japanese left behind in China were women, and these Japanese women mostly married Chinese men and became known as "stranded war wives" (残留婦人,zanryū fujin?). Because they had children fathered by Chinese men, the Japanese women were not allowed to bring their Chinese families back with them to Japan so most of them stayed. Japanese law only allowed children fathered by Japanese fathers to become Japanese citizens.
In these ten years, Japanese nationals living in China increased roughly three times from 46,000 to 127,000 in proportion to the growth in trade volume between the two countries.Gubei, Shanghai has the largest concentration of Japanese nationals in Mainland China.
