Japan's karoshi crisis has reached a new peak, with a record number of workers compensated for illnesses or deaths caused by excessive work. The latest data from the Ministry of Health reveals that the government recognized 1,310 cases eligible for compensation in the last fiscal year—the highest ever—and received 6,212 applications, another record. This marks the fourth consecutive year of record-breaking figures, underscoring a persistent and growing problem.
What Is Karoshi and Why Is It Making Headlines Again?
Karoshi, literally "death from overwork," refers to fatalities or disabling illnesses—such as strokes, heart attacks, and severe mental health disorders—triggered by extreme work hours and stress. The term has been part of Japan's social lexicon for decades, yet the latest government statistics show the issue is far from resolved.
The Ministry of Health's annual report tracks claims for workers' compensation related to overwork. The record numbers for fiscal 2025 indicate not only that more people are suffering but also that awareness and reporting may be increasing. However, experts caution that official figures are just the tip of the iceberg, as many cases go unreported or unrecognized.

The Alarming Trend Behind the Numbers
While the absolute numbers are striking, the trend is even more concerning. The fourth consecutive year of record claims suggests a systemic failure to address the root causes of karoshi. Despite government initiatives and corporate reforms, the pressure to work long hours remains deeply embedded in Japan's corporate culture.

According to The Japan Times, the rising number of applications—whether approved or not—signals growing awareness among workers of their rights. Yet it also reflects a worsening work environment where employees feel compelled to push themselves to dangerous extremes.
Key Takeaways from the Latest Karoshi Data
- Record compensation: 1,310 workers received government compensation for karoshi-related conditions in fiscal 2025, the highest on record.
- Record claims: 6,212 applications were filed, indicating a growing recognition of the problem.
- Fourth straight year of records: The trend shows no sign of reversing.
- Underreporting likely: Official figures may not capture the full extent of the crisis.
- Cultural roots: Long working hours and loyalty to employers remain deeply ingrained in Japan's work ethic.
Who Is Affected by Karoshi?
Karoshi affects workers across industries, but certain sectors are particularly vulnerable. Transportation, construction, healthcare, and IT are known for long hours and high stress. The victims are often middle-aged men, but increasingly, younger workers and women are also at risk.
The Japanese government has introduced measures such as work-hour caps and mandatory health checkups, but enforcement remains weak. Many companies still expect employees to work overtime without pay, and the stigma around mental health makes it difficult for workers to seek help.

Why This Matters Beyond Japan
Japan's struggle with karoshi is a cautionary tale for other developed economies. As work pressures intensify globally, the line between dedication and self-destruction blurs. The Japanese experience shows that without robust enforcement and cultural change, even well-intentioned policies can fail. The background to this story is set out in Trending: latest articles.

Moreover, the economic impact is significant. Lost productivity, healthcare costs, and compensation payouts strain public finances. For businesses, reputational damage and legal risks are growing concerns. Earlier coverage in South Korean Man Overstays 15-Day Japan Visa by 33 Years shows how the argument developed.

What to Watch Next
Activists and labor unions are calling for stricter penalties for companies that violate work-hour regulations. The government is reviewing its karoshi prevention guidelines, but critics argue that voluntary measures are insufficient. The coming year will test whether Japan can break the record-breaking streak or if the crisis will continue to escalate.
