Korea and Japan are holding their first working-level talks on the so-called "comfort women" issue in Seoul, on this Wednesday.
Officials say the Korean representative, Lee Sang-deok , director general of the Foreign Ministry's Northeast Asian Affairs Bureau, will reiterate Seoul's demand for an official apology and legal compensation from Japan for the Japanese military's wartime sexual slavery of Korean women.
Tokyo claims the issue was resolved through a 1965 treaty, when the two countries normalized diplomatic ties.
Wednesday's meeting is the result of an agreement reached ahead of a trilateral summit in The Hague between Korea, Japan and the United States, last month.
Around 200-thousand women, mostly Korean, were forced to serve the Japanese army in comfort stations in the early 20th century.
