This article explores the current state of mental health in Japan and discusses how it can be improved. It looks at the prevalence of mental illness in Japan, which is lower than in other countries, but still a significant issue due to social stigma and limited access to professional help. The causes of poor mental health are examined, including poverty, unemployment, overcrowding, family problems and modernization. The impact on society is also discussed, including an increase in crime rates and an overall decrease in productivity due to absenteeism from work or school caused by depression or anxiety disorders. Solutions are proposed to improve mental health in Japan such as creating more awareness through public campaigns and providing better access for those who need help.
