Further searching gives an indication to the shame. It has also created a backlash with a few men wrongly accused.
It would certainly be "nice" that what happened is what you describe: people would work together to stop it and ruin the lives of those who do it such that it creates a deterrence. Unfortunately, there is a societal belief that one can treat young women like that. I do not mean to beat up Japan--much--but think of how molesters get away with it in any culture. Read about the "man-boy" culture in Afghanistan if you find your day has just been too pleasant.
I am trying to avoid said Wall of Text, but I fear some of it is the Colossal Over-Generalization of prudishness in "the West" versus Japan.
This just goes back to the point of culture needing a change so that such incidents are no longer thought of as trivial and victims as someone who's "asking for it." But I don't think separating women into different train cars is a step in solving this problem.
