This article explores the causes and effects of stress in Japan, a problem that affects all cultures but is particularly prevalent in Japan. Stress can be attributed to long working hours, high expectations from employers and peers, and pressure to conform to societal norms. The impact of stress on Japanese society can be seen in increased mental health issues such as depression and anxiety, as well as physical health problems such as hypertension, heart disease, and stroke. The government has taken steps to address these issues through initiatives such as providing more access to mental health services, increasing awareness about mental health issues, reducing working hours and providing better support for employees. Individuals can also manage their stress levels more effectively by taking time for themselves, exercising regularly, getting enough sleep, talking about their feelings and seeking professional help if needed. Non-Japanese citizens living in Japan can also play an important role by being understanding towards cultural differences and offering support when needed.
