China's State Archives Administration plans to release videos documenting the suffering of sex slaves at the hands of the Japanese military more than 70 years ago. The eight-part video series will be released on the administration's website, one per day until August 23rd.

An estimated 200,000 "comfort women" were forced into sexual servitude by Japanese troops. Only a handful are still alive, and few have publicly admitted to the role they were forced into. Thousands took their secret to the grave without receiving any apology or compensation from Japan.

The State Archives Administration calls the Japanese actions "horrific, institutionalized acts of violence" and one of the most painful chapters in history. Japanese Prime Minister Shinzo Abe's Friday statement to mark the 70th anniversary of the end of World War II made no direct reference to the "comfort women".
