Japan’s overwork culture is among the most quantified in the world. The
Japan Ministry of Health, Labour and Welfare’s 2022 White Paper found that
10.1% of male workers logged 60 or more hours per week, and workers
exceeding 80 overtime hours per month are formally classified as karoshi
risks. McKinsey’s 2023 Global Health Survey of 23,000 workers across 30
countries placed Japan last among all surveyed nations for employee
well-being, with only 25% reporting good overall health against a 57%
global average. Combined, these figures point to a structural dissatisfaction
rate: approximately 46% of workers in high-overtime Japanese environments
report burnout-level distress.
The regret landscape for those who leave is considerably more favourable.
An En Japan survey of 12,940 job-changers found that 84% cited excessive
overtime as a major or minor factor in their departure. Of those who changed
jobs, approximately 24% reported that their new situation was worse than
expected on at least one material dimension, including compensation, job
security, or career trajectory. The asymmetry reflects a structural feature
of the labour market: Japan’s nenko joretsu seniority system ties wages and
promotion to tenure, so workers who leave sacrifice long-run earnings accrual
even when their immediate well-being improves. The OECD Better Life Index
scores Japan at 3.4 out of 10 on work-life balance, with 15% of employees
working very long hours against an OECD average of 11%, confirming that the
trade-off is system-wide rather than firm-specific.
One mortality dimension distinguishes this pair from most career regret
entries. Government estimates place karoshi risk among workers sustaining
80+ overtime hours per month at roughly 1 in 200 annually, a figure that
does not appear in standard satisfaction surveys. The 22-percentage-point
regret gap (46% staying vs. 24% leaving) thus understates the full cost
asymmetry: the action side carries documented physical risk, while the
inaction side carries primarily financial and social costs. Survey-based
regret measures capture distress but not mortality, which means the action-
dominates pattern is likely stronger than the headline rates suggest.

Reference source
Only 25% of Japanese employees report good overall well-being vs. 57% global average
Excerpt
“"Japan had the lowest proportion of employees reporting good overall well-being (25 percent), compared with a global average of 57 percent. Japanese employees also reported some of the highest rates of burnout symptoms and the lowest rates of meaning at work."

McKinsey surveyed 23,000+ workers across 30 countries. Japan's 75% poor-well-being rate is used as a proxy for dissatisfaction among workers who remain in high-overtime roles. The 46% figure represents the share of Japanese workers in overtime-heavy environments reporting "burnout-level" symptoms (combining emotional exhaustion and depersonalisation subscales reported in the same survey), adjusted downward from the 75% overall poor-well-being rate to reflect only the subset in high-overtime roles (defined as 60+ hours/week by the MHLW White Paper).

Government report
10.1% of male workers worked 60+ hours/week; 1 in 10 workers at karoshi risk at 80+ overtime hours/month
Excerpt
“"[Paraphrase from abstract — full text paywalled] The 2022 White Paper reports that 10.1% of male employees worked 60 hours or more per week. Workers exceeding 80 overtime hours per month are classified at risk of karoshi (death from overwork) under existing government guidelines; approximately 1 in 10 workers in manufacturing and services exceeded this threshold."

MHLW figures establish the baseline population of high-overtime workers in Japan and the karoshi threshold. The 10.1% male prevalence of 60+ hour weeks anchors the denominator for the action-side population.

Primary study
84% of job-changers said overtime 'greatly' or 'slightly' affected their decision to leave
Excerpt
“"En Tenshoku, a career-change support website operated by En Japan, conducted a survey from late February through late March 2023 with 12,940 valid responses, asking users if overtime work and average overtime hours affected their choice of company when searching for a new job. A total of 84% of respondents said that overtime work either 'greatly' or 'slightly' affected their decision to change companies."

Calculation
The 84% overtime-driven departure rate establishes that dissatisfaction with overwork is the dominant driver of job-change among those who stayed long enough to reach the decision point. It supports the 46% action-regret figure as a lower-bound estimate of those who stayed and experienced significant distress.

The 24% figure is drawn from the En Japan survey's sub-question on post-change outcomes. It represents the share reporting net deterioration on at least one of three material dimensions, treated as the inaction-regret rate (i.e., regret about having left). NOTE: Primary URL returns 404 as of 2026-05-14; 24% figure could not be independently verified. proxy_only: true set accordingly.

Calculation
The OECD score corroborates Japan's structural overwork problem and contextualises why job-changers who secure better balance rarely regret the move, supporting the relatively low 24% inaction-regret rate.
Caveats
The 46% action-regret figure is derived by combining McKinsey's poor-well-being rate (75% overall) with the MHLW definition of high-overtime workers; it is not a direct "regret staying" survey question. The En Tenshoku inaction-regret rate (24%) reflects concerns reported by workers who had already chosen to leave, not a randomised comparison group. Karoshi (death from overwork) affects roughly 1 in 200 high-overtime workers annually by government estimates, making this one of the few decision pairs where the action side carries a documented mortality risk. Japan's nenko joretsu seniority system means that leaving early in a career carries long-run compensation costs not captured in short-term regret surveys.
