The government is pushing for the inclusion of records concerning sex slaves for the Japanese Imperial Army on the UNESCO World Heritage list.
The Ministry of Gender Equality and Family said Tuesday the move would "raise global awareness so that such a tragedy will never happen again."
A ministry official said "tens of thousands of records" have been obtained from women who were forced by imperial Japan to serve as sex slaves for soldiers during World War II. The records include interviews, photos and drawings made by the victims as part of psychotherapy.
The government plans to gather data from victims in other parts of the world.
Kim Jae-ryun at the ministry said, "We are looking to push forward the date of the listing to 2015 by applying in conjunction with other nations." The victims also included Chinese, Filipino and a handful of Western women.
