Last year, train lines in Tokyo introduced women-only cars to reduce these groping incidents, perpetrated by chikan, the Japanese word for molesters. Groping complaints on trains tripled from 1996 to 2004, prompting train operators to take action. Granted, avoiding handsy fellow passengers isn’t the only benefit:

But the reasons women seek out these carriages are not always straightforward. “I don’t go out of my way to ride on them,” said Akane Kojima, a 30-year-old Tokyo office worker. “If I were to do so, it wouldn’t necessarily be to escape the perverts but to escape the various bodily odors that men emanate, particularly during the summer months.”

Other benefits include a respite from the often racy advertisements that fill the various train lines. The specially marked trains generally run during the super-crowded morning commute hours. A few befuddled men find themselves in the relatively uncrowded female-only cars, but are generally steered toward the crushed embrace of their fellow men.

Western travelers can identify the trains by the hot pink signs designating the cars as “Women Only”. Helpfully, the signs are printed in English as well as Japanese.
