Of the 42,364 billion yen spent in medical expenses in 2015 in Japan, only 1,924 billion yen was spent on psychiatric medicine, accounting for 4.5% of total expenditure. However, as shown in Table 1, the share of the number of hospitals and beds was 12.6% and 21.3% respectively.
A major problem of psychiatric medicine in Japan is that the average length of stay was as long as 270 days as of 2016 (Figure 1). According to the Organization for Economic Co-operation and Development (OECD) data, this duration was less than 50 days for those in other developed countries. Therefore, the Japanese government is working to create a system that allows psychiatric patients to be independent in the community in order to prevent long-term hospitalization, but there are many problems to be solved.
