Tokyo hit nearly 38 degrees Celsius this summer, turning standard concrete office districts into literal saunas. Faced with record heat waves, the Tokyo Metropolitan Government decided it was time for drastic action. They told city employees to ditch the suit jackets, unbutton their collars, and show up in shorts.
It seemed like a sensible move for energy conservation and employee survival. Instead, it ignited a fiery debate across Japanese corporate culture.
Walk into a Tokyo office building today and you might see middle-aged men sitting at their desks in polo shirts and tailored shorts. But for many coworkers, especially female colleagues, the sudden exposure of bare shins has been a jarring sight. The backlash was so immediate that internet users quickly coined a brand new term for the phenomenon: sunehara, short for shin harassment or leg hair harassment.
What started as an environmental initiative to lower air conditioning usage has exposed a complicated web of corporate double standards, generational clashes, and shifting beauty norms in Japan.
The Heatwave Push That Shattered Corporate Traditions
Japanese salaryman culture built its identity on uniform dark suits, crisp white shirts, and dark ties. Even after former Environment Minister Yuriko Koike introduced the original Cool Biz initiative back in 2005 to encourage lighter summer clothing, most corporate dress codes remained notoriously rigid. Short-sleeved button-downs were acceptable. Shorts were strictly forbidden.
That changed when municipal officials decided to lead by example under the renewed Tokyo Cool Biz guidelines. Watanabe Noboru, a 53-year-old Tokyo environmental official, made headlines when he traded his standard trousers for khaki shorts and a T-shirt. He noted that coworkers said he looked younger and more approachable, adding that the lighter gear made the grueling summer temperatures tolerable.
However, government encouragement is one thing. Public acceptance inside private offices is another matter entirely.
The Numbers Behind the Shin Harassment Phenomenon
Is the outrage just loud social media chatter, or do people actually mind seeing male legs in the workplace? Men's cosmetic provider Gorilla Clinic ran a detailed online survey of 800 Japanese adults aged 20 to 59 to find out.
The results show a country deeply divided over the issue.
- 53.5% of respondents opposed men wearing shorts to work during summer.
- 46.5% supported the decision to allow shorts.
- 45.5% of those who opposed shorts cited concerns over body shape or visible body hair as their primary reason.
The survey revealed something even more striking about visual perception. Acceptance wasn't really about the shorts themselves. It was about what was on the legs.
When shown a picture of a man wearing a professional jacket with shorts and visible leg hair, only 24.1% of respondents found the outfit acceptable for the office. But when shown the exact same outfit on a model with hair-free legs, the approval rating surged to 58%.
For many workers, the problem isn't the fabric. It's the forest of hair sitting next to the copy machine.
Double Standards in Workplace Appearance
The sunehara backlash isn't solely about aesthetics. It runs much deeper into the reality of gender roles in Japanese corporate life.
Many female workers have voiced frustration over what they view as a blatant double standard. For decades, Japanese women in corporate environments have faced intense pressure regarding their appearance. Many workplaces expect women to wear pantyhose, pumps, and full makeup, regardless of how hot it gets outside. High-profile movements like #Kutu (a play on the Japanese words for shoe and pain) previously highlighted how women were forced to wear high heels to work.
When municipal guidelines suddenly granted men permission to wear shorts and sneakers while women felt obligated to maintain traditional professional attire, resentment flared.
Critics rightly point out that women spend significant time, money, and energy on hair removal, foot care, and expensive business wear. Expecting female employees to adhere to meticulous grooming standards while male colleagues show up in relaxed lounge attire feels uneven. If men are going to bare their shins, critics argue, appearance standards need to evolve fairly for everyone.
The Rise of Male Laser Hair Removal in Japan
Faced with accusations of sunehara, Japanese men are reacting in a very practical way. They are heading straight to cosmetic clinics.
Akifumi Funatsu, a director at Gorilla Clinic, noted a distinct surge in male clients seeking laser hair removal specifically for their legs. These men aren't just looking to smooth their skin for aesthetic reasons. They see leg hair removal as a matter of modern social etiquette when wearing shorts to work.
Male grooming in Japan has been trending upward for years, but the official push for office shorts accelerated it overnight. Japanese men who want the comfort of shorts are finding that shaving, trimming, or permanently removing leg hair is the price of admission to avoid making colleagues uncomfortable.
Retailers are capitalizing on the moment too. Japanese fashion brands have launched specialized summer sets designed specifically for the office. Some look like sleek tailored shorts paired with lightweight blazers, while others resemble matching linen pyjama sets. Yet even with new retail options, adoption remains slow. Only about one-third of survey respondents said shorts were currently permitted in their own workplaces.
Finding Balance in the Modern Office
Transitioning away from century-old dress codes won't happen overnight, but severe weather demands practical changes. If your organization is navigating relaxed dress policies, keeping a few straightforward guidelines in mind makes the transition smoother for everyone.
- Establish clear grooming guidelines. If shorts are permitted, set clear rules on length and overall neatness so employees aren't guessing what is acceptable.
- Apply flexibility equally. Ensure relaxed dress rules apply across all genders without hidden expectations or double standards.
- Keep client-facing expectations distinct. Differentiate between internal office workdays and external client meetings where formal attire remains appropriate.
- Focus on breathable fabrics first. If shorts aren't realistic for your specific industry, promote lightweight linen trousers and moisture-wicking dress shirts as a middle ground.
Extreme heat waves aren't going away, and rigid wool suits simply don't make sense in 38-degree weather. Tackling the dress code debate directly keeps employees comfortable while maintaining mutual respect across the entire office floor.
