Women in Tokyo have reported experiencing so-called "leg hair harassment" after local authorities encouraged men to wear shorts as a way of coping with a severe summer heatwave. The advice, aimed at helping people stay cool amid soaring temperatures, has instead sparked complaints from women who say they are being subjected to unwanted comments and stares over the visible body hair on men's exposed legs, highlighting a clash between practical heat-safety guidance and social attitudes towards grooming and appearance.

The controversy has emerged as part of a wider discussion in Japan around how to manage extreme heat, with officials keen to promote lighter, cooler clothing to reduce the risk of heat-related illness. However, the backlash illustrates how such public health messaging can collide with entrenched social norms, with some women describing the situation as a form of harassment linked to men's bodily appearance rather than the clothing choice itself. The episode has drawn attention both in Japan and internationally as an unusual side effect of the country's efforts to help its population cope with rising temperatures.
