A nationwide online survey of 100,000 people in Japan found that 14.8% of men and 17.7% of women were classified as high-stress, with younger adults (20s and 30s), those with short sleep time, long working hours, and low household income being most affected.
Key Findings
Results
The proportion of individuals classified as high-stress differed by sex, with 14.8% of men and 17.7% of women meeting the high-stress threshold.
Respondents with stress test scores of 77 or more were classified as the high-stress group; those below 77 were classified as the non-high-stress group.
The survey included 100,000 men and women registered with an online survey company in Japan.
Women had a higher proportion in the high-stress group compared to men (17.7% vs. 14.8%).
Results
Younger adults in their 20s and 30s had a significantly higher proportion of high-stress individuals compared to other age groups, for both men and women.
The proportion of men and women in their 20s and 30s in the high-stress group was significantly higher than other age groups.
This age-related pattern was consistent across both sexes.
The finding suggests that younger working-age adults bear a disproportionate stress burden in the Japanese population.
Results
The most common stress coping methods for both men and women in the general population were 'sleeping' and 'bathing.'
These two methods were the top-ranked coping strategies across the full sample regardless of stress classification.
Coping method data were collected as part of the nationwide online survey of 100,000 respondents.
These passive, home-based strategies appear to dominate stress coping behavior in Japan.
Results
Stress coping methods differed between the high-stress group and the general population, with 'receiving chiropractic massage' being most common for high-stress men and 'spending time in the bathroom' being most common for high-stress women.
High-stress men most commonly reported 'receiving chiropractic massage' as their primary coping method.
High-stress women most commonly reported 'spending time in the bathroom' as their primary coping method.
These coping preferences in the high-stress group differed from the overall population trends of 'sleeping' and 'bathing.'
Results
Binomial logistic regression analysis identified 'short sleep time,' 'long working hours,' and 'low household income' as significant factors associated with being in the high-stress group.
Logistic regression was used to identify factors influencing membership in the high-stress group.
Three key predictors emerged: short sleep time, long working hours, and low household income.
These factors represent both behavioral/lifestyle and socioeconomic dimensions of stress risk.
The analysis was conducted on a sample of 100,000 respondents, providing substantial statistical power.
Conclusions
The authors conclude that the stress factors and coping methods identified are important health issues for the entire nation and are relevant to preventive medicine and public health.
The study was framed as providing 'basic data for stress management by clarifying the current state of stress among the general public and how they cope with stress.'
The authors state the findings 'will contribute to preventive medicine and public health, which aim to reduce stress among the general public.'
The nationwide scope (100,000 participants) was intended to represent the general Japanese population.
What This Means
This research surveyed 100,000 people across Japan to understand how stressed the general public is and how people cope with that stress. Using a standardized stress scoring system, the researchers found that about 1 in 6 women (17.7%) and roughly 1 in 7 men (14.8%) were classified as highly stressed. People in their 20s and 30s were the most stressed age group, and having less sleep, working longer hours, and having a lower household income were all linked to being in the high-stress category.
The study also revealed interesting patterns in how people manage stress. For the general population, the most popular methods were simply sleeping and taking baths. However, highly stressed individuals tended to seek different outlets — highly stressed men were most likely to get chiropractic or massage treatments, while highly stressed women were most likely to spend extended time in the bathroom, suggesting these groups seek more deliberate or prolonged forms of relief.
This research suggests that stress is a widespread public health concern in Japan, particularly among younger working-age adults and those facing economic hardship or poor work-life balance. The findings may be useful for designing stress prevention programs at a national level, highlighting that improving sleep, managing work hours, and addressing income inequality could be meaningful targets for reducing population-level stress.
