WASHINGTON (Yonhap) ― A memorial to Korean and other Asian women forced into sexual slavery by Japanese troops during World War II will be set up in a county adjacent to Washington this week, informed sources here said Monday.

The 1.5-meter-wide, 1.1-meter-tall monument, the seventh of its kind to be established in the U.S., will be unveiled in a Friday ceremony at the Peace Memorial Garden behind the Fairfax County Government building in Northern Virginia, they said.

It gives a brief introduction to Japan’s wartime atrocity and a call by Rep. Mike Honda for the nation’s formal apology and proper compensation, according to the sources.

The monument is flanked by two butterfly-shaped benches.

Butterfly was chosen as a symbol of hope by a group of victims.

This project was brought to fruition after year-long efforts by the Korean Council for Women Drafted for Military Sexual Slavery by Japan in Washington and the Comfort Women Memorial Committee.

The groups plan to hold a press conference on Tuesday to release details of their campaign.

They have pushed for the construction of the structure relatively in a low-profile manner due to worries that Japan may lobby to block the move.

The first local memorial to the so-called comfort women was established in New Jersey in 2010. There are another five such monuments in the United States.
