It was well illustrated by the "monument to the dedication made by the Pyongyang branch of the women's society for national defence of Imperial Japan" discovered on Moran Hill in Pyongyang in July 2005.

The "monument", 2.5 meters high, 25cm wide and 25cm thick, was erected in May 1942 in praise of "patriotism" displayed by the Japanese women in the branch for the interests of Japan.

The women's society was a reactionary organization, the members of which were the wives of Japanese aggression army officers.

The "women's society for national defence" was first organized in the Osaka Division and the "women's society for national defence of Imperial Japan" was organized in Tokyo in October 1932 under the aegis of military ministers.

Later, the society had its branches in Korea, China, Sakhalin, the South Sea Islands, etc.

It played a noticeable role in Japan's aggression of the Asian Continent.

15 branches were active in Hwanghae and Phyongan provinces, under which there were 175 sub-branches.

Their activities were aimed at covering up the true colors of Japan's fascist repressive policy and dampening people's resistance against Japan in colonized countries.

They actively carried on propaganda activities among Korean women to make them serve the Japanese army as sexual slaves.

The fact gives a glimpse of the crimes of the society.
