AKIPRESS.COM - People in South Korea and Taiwan unveiled monuments and staged protests on Tuesday to mark Japan’s wartime use of “comfort women”, a euphemism for girls and women forced to work in Japan’s wartime brothels, Reuters reports.

In South Korea, a new monument was unveiled as part of its first “Memorial Day for Japanese Forces’ Comfort Women Victims,” which threatens to exacerbate a sensitive diplomatic issue with Japan, South Korea’s neighbor and a key ally of the United States in efforts to contain North Korea.

“My hope is that this issue will not lead to a diplomatic dispute between South Korea and Japan. I also do not think that this will be solved by a bilateral diplomatic solution,” South Korean President Moon Jae-in said in commemoration of the day.

Moon said the issue involves “the entire world” and human rights of women as a whole, and pledged the South Korean government will respect the women as the main parties of the issue, and pursue commemorative projects to restore their honor and dignity including discovery, preservation and propagation of records.

Japan has said the issue was resolved by a 2015 deal, struck by a previous, conservative South Korean administration, under which Japan apologized to the victims and provided 1 billion yen ($9.03 million) to a fund to support them.

But South Korean President Moon Jae-in’s administration has spotlighted the emotionally-charged issue and has called for Japan to do more, despite backing down in January from formally renegotiating the deal.

In March, Moon described Japan’s wartime use of comfort women as “crimes against humanity”, with Japanese Chief Cabinet Secretary Yoshihide Suga calling Moon’s remarks “extremely regrettable.”

Tokyo has protested over other existing monuments in South Korea dedicated to comfort women, including one in front of the Japanese embassy in Seoul, as well as the move late last year to establish a day to remember comfort women.

August 14 was chosen because on August 14, 1991, South Korean comfort woman victim Kim Hak-sun became the first to give a public testimony about her experience, according to the country’s Ministry of Gender Equality and Family.

A think-tank funded by the South Korean government devoted to researching the issue also opened earlier this month.

The comfort women issue has been a regular cause for contention between Japan and neighbors including China and North and South Korea since the war.
