This study aimed to use open data to describe nationwide utilization of the psychiatric emergency admission fee, introduced in Japan in 2002 to promote high-acuity psychiatric units. Annual trends from fiscal years 2013 to 2023 were examined using statistics from the National Database of Health Insurance Claims (NDB), published as part of the Mental Health and Welfare Data, while differences by age, sex, and prefecture were analyzed using NDB Open Data for fiscal year 2024. The annual number of patients rose from 34,845 in 2013 to 57,394 in 2023, and the number of institutions submitting claims increased from 118 to 180; the number of prefectures with no claims fell from 8 in 2014 to 3 in 2024. In 2024, patient numbers peaked in the 50–59 age group for both sexes, and women outnumbered men in every age group. Per 100,000 population, the highest rate was observed among men aged 90 and older (97), while women showed a bimodal distribution, with peaks at ages 20–29 (70) and 80–89 (62). Nationwide, the number of patients per 100,000 population was 43.7, ranging from 124.2 in Yamagata to 12.1 in Tochigi, representing a tenfold difference across prefectures. The authors emphasize that the increases in patient and institution numbers, together with the decline in the number of prefectures with no claims, indicate nationwide improvements in psychiatric emergency care. However, disparities between prefectures persist, and standardization is essential to ensure equitable access. Limitations included the lack of detailed individual patient data, such as diagnoses, and the exclusion of admissions covered by other admission fees because the study examined only the fee for the highest-acuity emergency admissions.
