But now, there is some temporary relief for Japanese women -- a train car of their own. It's just an experiment now, and only during rush hour, but for those who have been harassed, it has made a huge difference.

One woman passenger told ABC News, "Because it's just only girls, females, and we don't touch, you know, so … [it's] very safe!"

Even most men seem to think the women-only cars are fair. Many men worry about being falsely accused of groping if they accidentally brush up against a woman in a packed train. Gropers can be imprisoned for up to seven years or fined up to $485.

But there's also some grumbling, especially in overcrowded adjacent cars, where the men are packed like sardines, while the ladies ride in comfort.

However, as one newpaper editorial in Tokyo suggested, the victims did not bring about the women-only experiment, but the "chikan."
