Six Filipino former sex slaves staged a rally Saturday near the entrance of the Philippine presidential palace as Benigno Aquino III held a meeting with Prime Minister Shinzo Abe.

"Justice for the grandmothers! Shinzo Abe, we are here, proof of the Japanese military's sexual slavery," Virginia Villarma, 84, shouted. "President Aquino, this is your chance. If you truly support us, convey our message to your friend, Shinzo Abe."

Villarma was 14 when Japanese forces housed her and her sister in a garrison in Manila's port area, forcing them to wash soldiers' clothes, cook food and cater to their sexual needs, she said.
