HIV/AIDS in Japan
Open-knowledge reference entry
Human immunodeficiency virus (HIV) first came to attention in the 1980s in the United States, followed by global interest in the years that followed. Among the many countries affected, Japan's population of affected people remains low in comparison to other developed countries such as the United States and European countries. The number of cases continues to rise. Official reports indicate that 6 homosexual men were diagnosed in 1985, which grew to 100 people infected by 1990.
The primary group affected in the 1980s was hemophiliacs, but that shifted to sexual transmission in the late 1980s and early 1990s. Due to poor media coverage and the lack of momentum from activist groups, large misconceptions about the disease, homosexuals, and foreigners spread about the general population.
Today, Japan remains one of the top providers of funds for global efforts such as the Global Fund to Fight AIDS, Tuberculosis, and Malaria and World Health Organization for HIV/AIDS prevention and treatment.
Epidemiology
In April 2016, sexual contact was the primary mode of HIV/AIDS transmission. In homosexuals, it accounted for 57.3% of all HIV cases and 38.7% of AIDS cases. Heterosexual transmission is responsible for 27.2% of HIV infections and 35.7% of AIDS infections.

Why this record matters
A short description can identify a subject without explaining its stakes. For “HIV/AIDS in Japan”, the useful work is to connect “open-knowledge reference entry” to the records capable of establishing context and consequence.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Dec 11, 2025. The linked authority identifier is Q5629855. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1985, 1990 and 2016.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
