A Tokyo museum is presenting a detailed view of wartime sex slavery in Okinawa through pictures, testimonies of residents and other documentary evidence, coinciding with the 40th anniversary of Okinawa's reversion to Japan from U.S. control.

In a yearlong exhibition through next June, the Women's Active Museum on War and Peace shows there were at least 145 "comfort stations" in the islands, at which women not only from Japan but also from Korea and Taiwan were forced to provide sex to Japanese soldiers.

The exhibition, "Comfort Stations in Okinawa and Sexual Violence by U.S. Forces," also introduces testimonies from 300 Okinawa women who were sexually assaulted by U.S. military personnel in the postwar era, although they are believed to be just the tip of the iceberg.
