Yoshie Arai, whose Korean name is Sin Jong Ho, looks at a print of a railway in the area where she lived in Tokyo before moving to North Korea in 1960. When she was 16 she started working at a factory owned by a Korean. There she met her future husband who was a colleague. They got married when Yoshie was 18 years old and moved to Korea in January 1960. ''We started working at a factory in Pyongyang a few days after we arrived here. And I also started learning Korean language as well.''
