For the fourth year in a row, Japan’s National Institute of Infectious Diseases in Tokyo (NIID) has reported more than 5,000 syphilis cases in the country. In 2020, 5,784 syphilis cases were reported in Japan with 1,550 reported in Tokyo and 889 in Osaka. Syphilis was a major issue in Japan until shortly after the end of World War II, but the total reported cases declined to several hundred annually until 2011, when a rebound began.
