As record-breaking heatwaves sweep across East Asia this summer, major Japanese corporations are relaxing strict dress codes and allowing male employees to wear shorts to the office. The sudden departure from Japan’s long-standing salaryman uniform—dark suits, conservative ties, and crisp white shirts—has triggered a fierce national debate over workplace decorum, hygiene, and the newly coined term “sunege hara,” or leg hair harassment.
From Cool Biz to Casual Workwear
For decades, Japan’s corporate sector maintained a rigid dress standard designed to signal uniformity, loyalty, and collective discipline. The first major crack in this tradition appeared in 2005 when the Japanese Ministry of the Environment launched the “Cool Biz” campaign, encouraging offices to set air conditioners to 28 degrees Celsius and allowing workers to ditch ties and jackets during summer months.
In recent years, escalating global temperatures and a post-pandemic shift toward flexible working arrangements have accelerated these changes. What started as tieless shirts has rapidly evolved into “Super Cool Biz,” with companies embracing polo shirts, sneakers, and now, hemline cuts above the knee.
According to a recent survey by Tokyo-based HR research firm Teikoku Databank, over 65 percent of Japanese firms have introduced flexible attire policies to boost employee comfort and reduce energy consumption. However, the step toward shorts has pushed cultural comfort zones further than previous iterations.
The ‘Leg Hair Harassment’ Contradiction
While proponents argue that shorts are an essential adaptation to climate change, critics contend that exposed legs violate professional boundaries. The friction has sparked widespread discussion across Japanese social media platforms and morning talk shows regarding visual comfort in shared spaces.
In corporate surveys, female colleagues and senior managers frequently voice discomfort over unkempt leg hair in client-facing environments. This sentiment gave birth to the buzzword “sunege hara,” reflecting concerns that exposed body hair might make coworkers uncomfortable or damage a firm’s public image.
Rather than banning shorts entirely, many enterprises are introducing specific grooming guidelines. Workplace handbooks now increasingly advise male workers to trim, thin out, or completely shave their leg hair if they choose to wear knee-length trousers.
Surging Demand in Male Grooming and Retail
The dress code evolution has created an unprecedented windfall for Japan’s male grooming and retail sectors. Beauty clinics in major metropolitan hubs like Tokyo, Osaka, and Yokohama report a dramatic surge in male customers requesting leg hair reduction and laser hair removal treatments.
Data from market research firm Fuji Keizai indicates that the Japanese male cosmetics and grooming market expanded by nearly 12 percent year-over-year, driven heavily by body hair care products. Consumer electronics manufacturers are similarly reporting record sales for body trimmers equipped with length guards specifically designed for subtle thinning.
Department stores and apparel brands have capitalized on the trend as well. Retail giants are prominently featuring tailored “business shorts”—crafted from moisture-wicking, wrinkle-resistant fabrics—paired with lightweight blazers to bridge the gap between comfort and professionalism.
Redefining Workplace Norms in Asia
Cultural experts view the shorts debate as a microcosm of a broader generational shift within Japan’s labor market. As the country faces severe labor shortages, companies are forced to modernize their corporate culture to recruit and retain younger talent who prioritize individual comfort and flexibility.
Industrial psychologists point out that rigid dress codes often act as a barrier to employee well-being, particularly in extreme weather conditions. Adapting attire to climate reality is increasingly viewed as an occupational health measure rather than merely a fashion statement.
The trend is also inspiring similar conversations in neighboring Asian financial centers like South Korea and Taiwan, where rising summer temperatures are challenging traditional office aesthetics.
Looking Ahead to Next-Generation Guidelines
As summer temperatures continue to set records across the region, industry observers expect the acceptance of casual corporate attire to become permanent rather than seasonal. Corporate Japan is moving toward a self-regulatory model, where dress codes focus on overall presentation rather than specific garments.
HR departments are expected to formalize inclusive grooming guidelines that balance personal comfort with professional boundaries. Observers will be watching whether leg hair removal becomes an implicit social requirement for men, or if Japanese corporate culture will ultimately embrace a broader definition of natural appearance in the workplace.
