Prevalence, treatment, and the correlates of common mental disorders in the mid 2010′s in Japan: The results of the world mental health Japan 2nd survey

The study found lower prevalence of mental disorders in Japan than in Western countries in the mid 2010's, suggesting that the prevalence of mental disorders remained stable in the last decade in Japan. Treatment rate increased for those with moderate disorders, which might reflect the government's attempt to raise people's awareness of mental health.
