Ten war-displaced Japanese headed back to China on Monday after spending two weeks in Japan under a Japanese government-sponsored program to search for their relatives.

Only one of them, Zhao Guiqin, 61, managed to find Japanese relatives. After having interviews with two Japanese women in Tokyo, Zhao found that one of them was her aunt, Tamako Yaguchi, 85.

They determined that they were related after sharing information about Zhao's family, including the Japanese names of Zhao and her twin sister, the Health, Labor and Welfare Ministry said.

The Japanese government started a program in 1981 to help war-displaced Japanese, who were left behind during World War II and its aftermath and grew up in China.
