The Japanese work ethic is renowned for its dedication, precision, and commitment to excellence. However, within this culture of dedication, an extreme form of work-related pressure has emerged: karoshi, or "death by overwork." The term encompasses a societal issue where work-life balance is often sacrificed for loyalty to employers, leading to adverse physical and mental health effects. In Japan, karoshi has come to symbolize a deeper cultural phenomenon and a complex relationship with work that has affected generations. Understanding karoshi involves exploring Japan's cultural roots, societal expectations, and efforts to shift away from this practice.
Historical Roots of Japanese Work Ethic
Japan’s work culture has deep roots, influenced by historical values of diligence, respect, and loyalty. These principles were shaped in part by Confucianism, which emphasizes loyalty to authority, and by the samurai code of bushido, where honor and duty were paramount. These values permeated Japanese society, blending with modern values during the Meiji Restoration and later after World War II, when Japan's economy transformed into an industrial powerhouse. In the 1950s and 1960s, Japan’s rapid economic growth was supported by a workforce willing to endure long hours and challenging conditions to rebuild the nation. Companies often treated employees like family, leading to lifetime employment systems that further entrenched loyalty, endurance, and dedication as cornerstones of Japanese work culture.
Defining Karoshi: "Death by Overwork"
Karoshi is a uniquely Japanese term that emerged in the 1970s, as Japan’s economic boom began showing cracks in the human cost of relentless work. It refers specifically to sudden death caused by excessive work, typically due to heart attacks, strokes, or suicide linked to chronic stress. Studies show that working more than 60 hours a week increases the risk of cardiovascular disease, hypertension, and even death. While work-related deaths exist globally, Japan’s high-pressure work culture, where employees feel bound to work excessive hours, has made karoshi a significant public health and social issue.
Causes of Karoshi: Societal Pressures and Company Culture
Several factors contribute to karoshi, rooted in both societal expectations and company culture:
1. Loyalty to Employers: A deeply embedded cultural expectation in Japan is to show dedication to one’s employer, often at the expense of personal well-being. Employees feel obligated to work overtime to demonstrate commitment, even if not explicitly asked. This is often unspoken but socially reinforced, making it difficult for employees to decline extra work.
2. Long Working Hours: Many Japanese companies expect employees to stay beyond standard work hours. Unpaid overtime, known as service overtime (sabisu zangyo), is common, especially for salaried employees who feel bound by loyalty to the company. Japan has among the longest working hours globally, with significant numbers working over 80 hours a week, a threshold often linked to increased karoshi risk.
3. Lack of Vacation Utilization: Japanese workers are granted paid vacation days but rarely take them. Fear of being viewed as uncommitted or burdening coworkers by being absent results in low vacation use. Taking time off is seen as a disruption, so many employees forgo their vacations, further contributing to fatigue and stress.
4. Social Stigma Against Work-Life Balance: Unlike some Western countries where work-life balance is increasingly prioritized, Japanese culture historically glorifies self-sacrifice. Those who prioritize personal time over work can be stigmatized as lacking dedication, and, as a result, workers often choose work over personal health and time with family.
5. Job Insecurity and Economic Pressure: With economic recessions and structural changes, job security has become less certain. Workers feel pressured to perform at peak levels to retain their positions. For younger generations, especially, the fear of layoffs has created a more competitive environment where overwork seems necessary for career survival.
The Psychological and Physical Toll of Karoshi
The impact of overwork on physical and mental health can be devastating. Chronic stress from prolonged working hours is linked to hypertension, cardiovascular disease, and impaired immune responses. Mental health impacts are also significant, with increased rates of depression, anxiety, and suicidal thoughts among overworked employees. Karoshi also affects families, creating strain due to absent parents or partners and loss due to stress-induced illnesses or suicides.
One infamous karoshi case involved the death of a young Dentsu employee in 2015, who worked over 100 hours of overtime the month before her suicide. Her case, which received considerable public attention, underscored the psychological and physical limits workers endure, sparking discussions and reforms regarding Japan’s work culture.
### Government and Corporate Responses to Karoshi
In response to the growing concern around karoshi, the Japanese government and businesses have introduced several reforms:
1. The Work Style Reform Law (2018): To address karoshi, the Japanese government passed the Work Style Reform Law. This legislation capped overtime at 100 hours per month and 720 hours annually, aiming to reduce excessive work hours. Companies are required to keep overtime within these limits to curb risks associated with overwork.
2. Premium Fridays: An initiative introduced by the Japanese government encouraged employees to leave work at 3 p.m. on the last Friday of each month. Though not widely adopted, Premium Fridays aimed to promote a healthier work-life balance by allowing workers to leave early and spend more time on personal interests or with family.
3. Encouragement of Remote Work: The COVID-19 pandemic led to an increase in remote work options, which offered a respite from long commutes and encouraged some companies to re-evaluate work expectations. While some companies returned to in-office norms post-pandemic, remote work did increase awareness around flexible work models.
4. Raising Awareness: The Japanese government established the Karoshi Hotline and other support services for those experiencing overwork stress. Public awareness campaigns aim to destigmatize work-life balance and encourage people to seek help.
5. Corporate Responsibility and Work-Life Balance Policies: Some corporations, particularly larger, progressive firms, have begun prioritizing work-life balance by instituting strict policies around overtime, encouraging vacations, and adopting mental health programs.
Changing Attitudes Among Younger Generations
Japan’s younger generations have begun to challenge traditional work expectations. Millennials and Gen Z workers are more vocal about the need for work-life balance and are increasingly willing to prioritize personal well-being over work. While older generations may view these attitudes as lacking commitment, younger employees are demanding change and often seek employment in companies with more progressive policies around overtime and flexibility.
Karoshi in International Perspective
While Japan’s karoshi culture is deeply rooted in its history, other countries, particularly in East Asia, face similar issues with overwork. South Korea, for instance, also contends with long work hours, intense corporate loyalty, and rising mental health concerns. Comparatively, Western nations have progressively moved toward promoting work-life balance, with countries like Sweden adopting six-hour workdays. Observing these models could inspire Japan to continue efforts toward reducing work-related stress.
Moving Toward a Healthier Work Culture
Japan’s shift from a high-stress work culture to a more balanced approach requires ongoing commitment. Emphasizing mental health, increasing transparency around working hours, and promoting flexible work arrangements are crucial. Educational programs that redefine loyalty—not as exhaustive dedication but as sustainable productivity—can also help change long-standing attitudes.
The Japanese work ethic, a blend of historical loyalty and post-war dedication, has contributed to Japan’s global reputation for hard work and excellence. However, karoshi reveals the darker side of this ethic, highlighting the urgent need for change. Japan’s government, companies, and society are gradually addressing these issues, though the journey to a balanced work culture remains complex. With new laws, evolving social expectations, and changing values among younger generations, Japan may one day redefine its work culture—maintaining its excellence without sacrificing well-being.
