Work-Life Stress in Japan: Exploring the Physiological Factors Behind Karōshi and Karōjisatsu

This study explores how personal and workplace-related factors influence perceived stress, anxiety, and depression among individuals in Japan, particularly those in salaryman-type occupations. Participants completed a self-report survey assessing variables such as number of children, work hours, perceived job control, esteem, influence, and promotional opportunities. The data was analyzed using bivariate Pearson correlations to identify relationships between these variables and mental health outcomes. Results revealed several significant findings. A strong positive correlation was found between the number of children and depression levels, while longer working hours were associated with decreased feelings of job reward, though not with increased stress. Additionally, perceived promotional opportunities and workplace esteem were negatively correlated with anxiety and stress, respectively. Contrary to the initial hypothesis, individuals with less perceived influence at work reported higher stress levels, suggesting that a lack of control may be more detrimental than high responsibility. These findings shed light on the psychological burden of hierarchical, rigid work environments. Although the sample size was small (n=6), this study offers possible initial insight into the psychosocial stressors contributing to issues like karōshi (death from overwork) and karōjisatsu (suicide due to overwork).
