An award-winning photojournalist has shed light on forgotten Japanese women who married Korean men and moved to North Korea during a 1959-1984 repatriation project.

"They have been in different settings since arriving in North Korea. Some of them have lost contact with their relatives in Japan, while some still wrestle with their conscience about leaving their families back in Japan," said Noriko Hayashi.

"Each of their lives is equally irreplaceable. And as most of them are getting old, we do not have that much time left to hear what they have to say," she added.
