Japanese Workers Embrace Shorts Amid Extreme Heatwave

by Chief Editor

Tokyo Metropolitan Government officials have begun wearing shorts, polo shirts, and sneakers to work as part of a “Cool Biz” initiative to combat extreme summer heat. With temperatures reaching 35 degrees Celsius and humidity levels at 72 percent, the shift away from traditional formal suits is a practical response to rising health risks, according to reports from The Straits Times and AFP.

The Evolution of ‘Cool Biz’ in Tokyo

The “Cool Biz” campaign was launched in 2005 by Yuriko Koike, who was serving as the Minister of the Environment at the time. The initiative was designed to help staff survive extreme weather by replacing formal suits. While the program initially focused on removing ties and suit jackets, the Tokyo Metropolitan Government is now encouraging the use of even more relaxed dress codes.

Toru Suda, a 34-year-old government employee, noted that while the transition to shorts and sneakers felt initially awkward, the collective shift among colleagues made the change practical. The policy is a measure to mitigate the physical strain of commuting and working in Japan’s sweltering summers, where the Japan Meteorological Agency and the Ministry of the Environment have issued emergency heatstroke warnings.

Workplace Flexibility vs. Traditional Corporate Culture

For many public servants, the casual dress code is a matter of necessity rather than fashion. Noboru Watanabe, head of the Tokyo government’s climate change team, stated that he has become so accustomed to the casual style that returning to formal trousers feels difficult. However, he maintains that he will wear formal attire when attending high-level state functions.

Takuya Ozawa, 38, another government official, described the transition as a significant improvement in personal comfort during his daily commute. Meanwhile, workers in the private sector, such as 30-year-old marketing employee Takayuki Deguchi, have expressed frustration with their own companies’ rigid dress codes. Deguchi advocates for similar flexibility in the private sector, citing the logic of regulating body temperature through clothing as a sensible approach to extreme weather.
