In Japan, the "Statistical Classification of Diseases, Injuries, and Deaths," based on the International Classification of Diseases (ICD), has been established as a statistical standard under the Statistical Law. The ICD is widely utilized for cause-of-death and disease classification in official statistics—such as Vital Statistics, patient surveys, and social medical practice statistics—as well as in medical records within healthcare institutions.Efforts have been made to align the Japanese terminology of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) with that of the ICD-11 wherever feasible. Following the publication of the Japanese version of DSM-5, the Liaison Committee of the Japanese Society of Psychiatry and Neurology (JSPN) continued to work on ICD-11 disease nomenclature. They solicited public comments in June 2018 and conducted a questionnaire survey in February 2019. Based on these inputs, a draft was reviewed and reported to the Delegate Assembly at the JSPN Annual Meeting in June 2019. Subsequently, in November 2019, the Society's draft was presented to the Terminology Management Committee of the Japanese Medical Association.In 2021, the ICD-11 Office of the Ministry of Health, Labour, and Welfare officially requested the JSPN to translate disease names and terms. During the translation of the DSM-5-TR into Japanese in 2023, the society's draft of ICD-11 disease names and terms was applied. The ICD-11 Committee has been simultaneously translating the Clinical Descriptions and Diagnostic Requirements (CDDR) into a Japanese version endorsed by the JSPN. In my lecture, I will discuss the history of introducing ICD-11 to Japan and the changes it will bring to clinical psychiatry.
