[Cabin in the Woods] How would the Japanese office have accomplished anything?

It is made very clear in the movie that the five specific kids needed to fulfill their roles and die, with the exception of the last one, who doesn't have to die, just needs to suffer.  It's also made clear that there are other offices around the world, and that they are attempting to appease the same Old Gods, and all failed, thus putting all of the pressure on the Cabin office.  The only other operation we see, though, is the Japanese one, and there are none of the archetypes needed for the sacrifice, only a bunch of elementary school Japanese girls.  If they hadn't failed, and the girls had been slaughtered, what would that have accomplished, if the sacrifice had to be as specific as it was established to be; one might say that the characters were simply misinformed, but that can't be true either; if an indiscriminate massacre is all that is necessary, then the Cabin facility wouldn't have failed.

Each office is placed in specified spots around the world where the distance with the Old Ones is small enough for the procedure be the most effective.  
It's to remember that each spot also responds to a slightly different kind of Old One, and their power and needs have affected their surroundings since the times when they were still around; Making the necessary sacrifices and rituals different.  
In resume, the old folklore of the place signifies a difference in the Old One residing underground, even if it's just enough to please one of them to keep them calm, each one takes pleasure in a different kind of sacrifice, some of them quenching their thirst with just a virgin as others need a small town to be reduced to gravel.
