Japan’s current government has made no secret of its distaste for the Kono Statement. During Mr. Abe’s first administration, in 2007, the cabinet undermined the Kono Statement with two declarations: that there was no documentary evidence of coercion in the acquisition of women for the military’s comfort stations, and that the statement was not binding government policy.

Shortly before he became prime minister for the second time, in 2012, Mr. Abe (together with, among others, four future cabinet members) signed an advertisement in a New Jersey newspaper protesting a memorial to the comfort women erected in the town of Palisades Park, N.J., where there is a large Korean population. The ad argued that comfort women were simply part of the licensed prostitution system of the day.

In June this year, the government published a review of the Kono Statement. This found that Korean diplomats were involved in drafting the statement, that it relied on the unverified testimonies of 16 Korean former comfort women, and that no documents then available showed that abductions had been committed by Japanese officials.

Then, in August, a prominent liberal newspaper, The Asahi Shimbun, admitted that a series of stories it wrote over 20 years ago on comfort women contained errors. Reporters had relied upon testimony by a labor recruiter, Seiji Yoshida, who claimed to have rounded up Korean women on Jeju Island for military brothels overseas.

The scholarly community had long determined that Mr. Yoshida’s claims were fictitious, but Mr. Abe seized on this retraction by The Asahi to denounce the “baseless, slanderous claims” of sexual slavery, in an attempt to negate the entire voluminous and compelling history of comfort women. In October, Mr. Abe directed his government to “step up a strategic campaign of international opinion so that Japan can receive a fair appraisal based on matters of objective fact.”

Two weeks later, Japan’s ambassador for human rights, Kuni Sato, was sent to New York to ask a former United Nations special rapporteur on violence against women, Radhika Coomaraswamy, to reconsider her 1996 report on the comfort women — an authoritative account of how, during World War II, imperial Japan forced women and girls into sexual slavery. Ms. Coomaraswamy refused, observing that one retraction did not overturn her findings, which were based on ample documents and myriad testimonies of victims throughout Japanese-occupied territories.

There were many ways in which women and girls throughout the Indo-Pacific became entangled in the comfort system, and the victims came from virtually every settlement, plantation and territory occupied by imperial Japan’s military. The accounts of rape and pillage leading to subjugation are strikingly similar whether they are told by Andaman Islanders or Singaporeans, Filipino peasants or Borneo tribespeople. In some cases, young men, including interned Dutch boys, were also seized to satisfy the proclivities of Japanese soldiers.
