Minju Joson Sunday in a signed commentary observes in this regard: By origin, the issue of the above-said remains was a hideous crime that should have been clarified already long ago but the Japanese authorities have glossed over the case, claiming that "they are likely to be part of the specimens of human bodies used by a military medical school" and "they have nothing to do with the 'unit 713'" and the like.

In the subsequent period there were more new evidence proving the experiments on human bodies conducted by the unit and the public attention was focused on this issue to give rise to the call for investigating the issue of the remains. This changed situation compelled the Japanese authorities to set about the work for unearthing the remains and investigating the case.

Brutal mass killings including the experiments on human bodies perpetrated by the Imperial Japanese Army against Korean people and other Asian people in the past were unprecedentedly hideous crimes.

Japan's settlement of its past crimes is a legal and moral duty and a historical task whose fulfillment should neither be delayed nor dodged any longer.

Japan should probe the truth behind such hidden crimes as the horrible experiments on human bodies committed by the unit, though belatedly.

The Japanese authorities seem to persistently evade the settlement of the crimes, calculating that their past crimes will remain buried into oblivion and forgotten by people with the passage of time and the replacement of the old generation by a new one.

This is, however, a gross miscalculation.

The monstrous crimes committed by the Japanese imperialists against the Korean people in the past will always remain recorded as crimes and they will snowball unless Japan goes on without settling its past crimes, warns the commentary.
