Tokyo’s “Cool Biz” Push Lets Men Wear Shorts, Sparking a Gender-Focused Dress-Code Debate

Core Policy Change
In April, the Tokyo Metropolitan Government expanded its “Cool Biz” programme, allowing office workers to replace suits, ties and jackets with T-shirts, trainers and, for the first time, shorts. Governor Yuriko Koike presented the update as a response to record-breaking summer heat and rising electricity costs. The guidance is advisory; employees choose clothing appropriate to temperature, duties and workplace norms.
Background & Context
The 2005 Cool Biz initiative promoted short-sleeved shirts and the removal of jackets to cut air-conditioning demand. After the 2011 Tohoku earthquake strained the power grid, the government introduced “Super Cool Biz,” further relaxing dress rules. The 2024 expansion adds shorts as an officially endorsed option for male staff in government offices and encourages private firms to follow suit.
Data & Statistics
- A June 17 online survey of 800 Japanese adults aged 20-59, conducted by Gorilla Clinic, found 53.5 % opposed wearing shorts at work and 46.5 % supported the recommendation.
- Among those opposed, 45.5 % cited concerns about body shape or visible leg hair; cleanliness and workplace etiquette ranked lower.
- Women comprised the majority of respondents and were more likely than men to view visible leg hair as off-putting.
- The Fire and Disaster Management Agency recorded seven heat-stroke deaths and 4,580 hospital admissions during the week of July 6-12, underscoring the public-health urgency.
Official Statements & Responses
The Japan Meteorological Agency now labels days above 40 °C as “kokusho-bi” (brutally hot day) to raise awareness of heat risks. The Fire and Disaster Management Agency advises residents to stay hydrated, use air-conditioning where possible and acclimatise gradually.
Criticism & Opposition
Women’s groups argue the policy creates a double standard: men may wear shorts, while many female employees remain expected to wear tights or long skirts. Online, the term “sunehara” (leg-hair harassment) describes discomfort at seeing male colleagues’ exposed shin hair.
Akifumi Funatsu, director of Gorilla Clinic, noted an increase in male clients seeking laser hair removal, calling it a matter of “social etiquette when wearing shorts.”
On-the-Ground Perspectives
Several office workers reported feeling more comfortable in shorts, citing reduced sweating and a perception of greater approachability. Some female staff said male leg hair distracts them and reinforces expectations that women maintain a more modest dress code.
Why It Matters
The policy aims to mitigate heat-related health risks, reduce electricity consumption, and modernise workplace culture. The gendered reaction highlights lingering expectations about professional appearance in Japan’s traditionally formal offices.
Conflicting Reports & Gaps
Sources consistently report the same heat-stroke figures for the week of July 6-12, but no data have been released on actual energy savings attributable to the shorts recommendation. The survey does not capture how many companies have formally updated dress-code policies to permit shorts.
What’s Next
Tokyo officials have indicated that the expanded Cool Biz guidance will remain in effect for the remainder of the summer, with no announced deadline for further revisions. The government has not specified any formal mechanism for monitoring compliance or measuring the policy’s impact on energy use.
