Evidence that foreign women were forced into sex slavery by the Japanese military during World War II has been found at the National Archives of Japan. This counters the Shinzo Abe government's claim that there is no such proof.

On request by a civic group to disclose the information, the archives recently unveiled official document showing that the Japanese troops had forced 35 Dutch women detained in a prisoner camp in Indonesia to serve as the so-called ‘comfort women,’ a euphemism for enforced military sex laborer or slave for the Japanese Imperial Army.

The 530-page document includes court records convicting five former Japanese officers and four civilians of rape in Indonesia after the end of the war. It also includes defendant testimonies made in Japan at a later time.

The document is titled ‘Batavia court file,’ after the old name of Jakarta.

A former Japanese Army lieutenant general was one of the convicted to receive a 12 year sentence. The record states that the lieutenant general was ordered by an officer in 1944 to take the Dutch women detained on the island of Java to four brothels where he threatened them into prostitution.

During an investigation later in 1966 in Japan, the lieutenant general testified that there was some degree of coercion when the women were asked to consent to serving the troops.

This document is believed to have been the basis for the 1993 Kono statement. Then Chief Cabinet Secretary Yohei Kono issued a statement acknowledging military involvement in the sexual enslavement and offering apology and remorse.

However, this is the first time the document itself has been disclosed. The disclosure debunks the Abe government's claim that there is no proof of administrative or military involvement in the sexual drafting of women.

In March 2007, the Cabinet of Prime Minister Shinzo Abe said based on documents found by the government, there are no accounts indicating that Japanese authorities were involved in the forced conscription of women.

Abe's second Cabinet launched in late 2012 remains unchanged in this stance. Some Cabinet members have even called for revisions to the Kono statement.

During World War II, the Japanese military forcibly recruited women from Korea, China and Southeast Asia to sexually serve its troops, and inflicted indelible pain on the lives of the young female victims.

The Tokyo government still refuses to take responsibility. Some Japanese officials have even claimed that the women were there voluntarily to make money.

However, evidences of Japan's wartime conducts continue to emerge rebuking such claims.
