Over 2,100 "comfort stations" across China have been confirmed as being part of Japan's "comfort women" system during World War II. Among the far more than the estimated 200,000 Chinese victims of the system, 358 survivors from the Chinese mainland were discovered, with only seven remaining.

These numbers are the results of the latest findings collected in a four-volume book written by professors Su Zhiliang and Chen Lifei, from the Research Center for Chinese Comfort Women at Shanghai Normal University.

A Comprehensive History of the Japanese Military 'Comfort Women' System is a book of two million words that comprehensively and systematically explores the system's diverse aspects with solid evidence, exhaustively unveiling its background, origin, development process, management, operation, postwar follow-ups, and more.

Released on Aug 14 at the 2025 Shanghai Book Fair to mark the International Memorial Day for Comfort Women, the book includes the married couple's fieldwork and research results conducted over three decades. It aims to close the gap left by those who deny the history and reveal the historical truths that Japan has been trying to bury.
