The Japanese Association of Medical Sciences (JAMS) began its activities in 1902 and was incorporated as an academic organ within the JMA in 1948. At present it comprises a total of 105 specialist Medical societies. The General Assembly of the Japan Medical Congress is held once every four years, constituting the largest medical congress of its kind in Japan, and brings together leading scientists in the fields of medicine and medical care.
Each year, the JAMS sponsors three symposia to promote and facilitate exchange of the latest information among medical researchers.
