Japan’s Osaka city has ended its “sister city” ties with San Francisco over the display of a statue depicting women forced to work as sex slaves for Japanese soldiers during World War Two.
Osaka mayor Hirofumi Yoshimura said the “comfort women” monument “destroyed the two sides’ relationship of trust”.
The work depicts three young women – from Korea, China and the Philippines – standing in a circle holding hands.
It is estimated that some 200,000 women were kept in these military brothels.
The statue on display in San Francisco, which was initially set up privately but officially accepted by the US city last November, is entitled the “Women’s Column of Strength”.
It represents the women who worked in the brothels at the time, including some who were reportedly lured with the offer of paid work as cooks or cleaners, according to a UN report.
Mr Yoshimura’s decision to end Osaka’s sisterhood with the city, which dates back to 1957, was first announced in November, but the move was delayed following the death of San Francisco Mayor Ed Lee in December.
Lee was later replaced by London Breed, the city’s first female black mayor.
Mr Yoshimura set out the reasons for his decision in a 10-page letter to Ms Breed, saying that part of the “problem” was the monument’s inscription, which he said “presents uncertain and one-sided claims as historical facts”.
“There is also disagreement among historians when regarding the historical facts such as the number of ‘comfort women’, the degree to which the former Japanese army was involved, and the extent of the wartime harm”, his letter adds.
The full inscription on the side of the statue reads: “This monument bears witness to the suffering of hundreds of thousands of women and girls euphemistically called ‘comfort women’, who were sexually enslaved by the Japanese Imperial armed forces in 13 Asian-Pacific countries from 1931 to 1945.”
The monument also includes a fourth figure who stands nearby, depicting an elderly woman meant to be Kim Hak-sun, the first woman to speak out about her experience during the Japanese occupation of Korea during the war.
A spokesman for Ms Breed described Mr Yoshimura’s decision as “unfortunate”, adding: “We will remain sister cities via the people-to-people ties maintained by our San Francisco-Osaka Sister City Committee and their counterparts in Osaka.”
