On September 22, 2017, in an initiative led by the local Chinese-American community, San Francisco erected a privately funded San Francisco Comfort Women Memorial to the comfort women of World War II. Some Japanese and Japanese-American opponents of the initiative argue the statue would promote hatred and anti-Japanese sentiment throughout the community and object to the statue singling out Japan. Tōru Hashimoto, the mayor of Osaka, Japan, objected that the memorial should be "broadened to memorialize all the women who have been sexually assaulted and abused by soldiers of countries in the world". Supporting the statue, Heather Knight of the San Francisco Chronicle pointed to the San Francisco Holocaust Memorial and the landmarked Japanese internment camps in California as evidence that Japan is "not being singled out". In protest over the statue, Osaka ended the sister city relationship with San Francisco that had been established since 1957. When the city accepted the statue as public property in 2018, the mayor of Osaka sent a 10-page letter to the mayor of San Francisco, complaining of inaccuracies and unfairly singling out Japan for criticism.
