Various expressions of regret and statements acknowledging the role of the Japanese military in operating the “comfort women” system have been made by government officials, but none, including the latest, has expressed an unconditional acknowledgment that Japan as a state was responsible.

As part of the latest “apology”, Japan pledged 1 billion yen (HK$65.2 million) for the creation of a South Korean foundation to support the surviving South Korean victims with medical, nursing and other support services. South Korea, in turn, pledged to “irreversibly” drop its demand for reparation, end all criticism of Japan on the issue and remove a memorial constructed by Korean “comfort women” survivors in 2011 in front of Japan’s embassy in Seoul.

Rather than fully acknowledge the state’s responsibility for initiating the system of “comfort stations”, the agreement offers a “heartfelt apology and remorse” but only for the “involvement of Japanese military authorities” in forcing women into sexual slavery. According to survivors and their advocates, this falls well short of a complete and meaningful apology. It does not recognise Japan’s role in establishing and maintaining the system of slavery. It does not accept legal responsibility for the violations. It fails to meet criteria set out in international human rights norms that a public apology must be an “acknowledgement of the facts and acceptance of responsibility”.

Our recent report, “More Than Words: Apologies as a Form of Reparation”, explains that the most meaningful public apologies clearly acknowledge responsibility for the violations and recognise the continuing pain of survivors and victims’ families. As it points out, apologies for massive and systematic war crimes and human rights violations should come as a result of consultations with survivors and victims’ families about the form, content and timing.

This was not the case for South Korea’s “comfort women” survivors. This is certainly not the case for all other survivors across Asia who are not covered by this agreement. Instead, this attempt at an apology appears to have come about through US encouragement. It was motivated less, if at all, by a desire to render justice but by a need to ease tensions between Japan and South Korea (including over territorial disputes and unresolved historical grievances).

The centre’s report emphasises that apologies should not end truth-seeking nor stifle truth-telling by victims. Instead, an apology should encourage a collective reckoning by society of conflict-related crimes or human rights violations carried out in the name of the state. An apology should open up space for accountability rather than close it.

Certainly, apologies should not be used to remove or devalue measures, such as memorials or monuments – especially those established by victims themselves – to ensure that violations are not forgotten. Memorials built by victims that are strongly supported by society are not for the government of the day, let alone a foreign government responsible for war crimes, to remove. That only adds grave insult to irreparable injury.

Apologies, too, should not discriminate among victims of the same violations. Indeed, Japan’s failure to mention the victims of its “comfort stations” in China, the Philippines, East Timor and other Asian countries supports the view that it was motivated primarily by political expediency rather than a genuine admission of past wrongdoing. By effectively discriminating against some victims, the gesture fulfils neither the spirit nor purpose of an official apology.

Finally, apologies should not be instrumentalised for other purposes that are inconsistent with the “never again” promise that they are meant to symbolise. Here, the apology for past crimes arguably does not reduce present regional security tensions – and may even escalate them. This not only diminishes its significance but turns the apology on its head by devaluing the victims’ decades-long demands for justice.

Japan could learn from recent examples of apologies for violations committed during occupation as part of reparations programmes that accompanied a state’s unequivocal acknowledgement of responsibility. The UK government apologised in 2013 for the torture and abuse of Kenyans suspected of supporting a movement against British colonial rule in Kenya. Britain also funded a memorial and paid compensation to survivors. In 1991, President Patricio Aylwin of Chile apologised on behalf of the state for violations committed by the Pinochet dictatorship. He made it clear that the state was responsible for the violations and that state agents had committed enforced disappearances, torture and extrajudicial killings. He followed up with a draft law for a reparations programme and an institution to implement it – which was enacted and continues to provide support to victims to this day.

The Japanese government has played a constructive role in promoting reparations as an element of transitional justice in the Rome Treaty that created the International Criminal Court. In 2014, it made a significant financial contribution to the Trust Fund for Victims that was created by the treaty as its reparations mechanism. Japan even asked that the donation be “earmarked for victims of sexual and gender-based violence”. In other words, despite political, diplomatic and security challenges that have marked Japan’s refusal and reluctance to apologise to the “comfort women”, it has shown that it recognises the importance not only of addressing sexual and gender-based violence in armed conflict but of the need for reparations to be made to victims.

The UN and national governments should now step in and ask Japan, after so many years, to unequivocally acknowledge its responsibility to “comfort women” for past sexual slavery crimes with a full and meaningful apology coupled with effective reparations.
