Japanese authorities are responding to the legendary overcrowding on Tokyo commuter trains. Railway officials say they can't actually relieve the crowding, but they can make it easier on women. In a survey, almost two-thirds of women between age 20 and 40 said they'd been groped by men in the crowded train cars. So the railroads are increasing the number of women-only cars. This protective measure has drawn protests from men, who call it discrimination.
