Futanari what’s this? In short – is the Japanese word for hermaphroditism, which is also used in a broader sense for androgyny.
If you expand it more, that is: Beyond Japan, the term has come to be used to describe a commonly pornographic genre of eroge, manga, and anime, which includes characters that show primary sexual characteristics from both females and males. In today’s language, it refers almost exclusively to characters who have an overall feminine body, but have both female and male primary genitalia . The term is also often abbreviated as futa(s), which is also used as a generalized term for the works themselves.
History of futanari. Where do they come from?
Japanese folk religion created diverse fantasies related to sexual characteristics. Traditional vocal pieces that date back hundreds of years deliver rough evidence that a change of gender was not ruled out: and that the representation of the gender was used to worship deities such as dōsojin, which sometimes had ambiguous gender, being neither male nor female. Gary Leupp adds that the origins might even reach back to the origins of Buddhism, since the deities would not necessarily have a fixed or determinable gender.
Likewise, the belief spread that some people could change their gender depending on the lunar phase. The term half-moon was coined to describe such beings. Japanese traditional clothing, which made distinguishing men from women more difficult, as in other cultures, presumably might have had an influence on this development. To restrict women from accessing prohibited areas and to avoid smuggling by hiding items in the belt bag, guard posts were assigned to perform body checks. Historical records indicate that guards liked to joke about this matter quite frequently, resulting in various stories and even poems. Whether anatomical anomalies, such as clitoromegaly or unusual physical development, led to these assumptions remains an open question.
Until 1644, when onnagata actors were required to adopt male hairstyles regardless of the gender they were portraying, actors playing characters such as female warriors capitalized on the interest in the futanari quality, which was common in both samurai and commoner society.
Anime and manga
Originally, the Japanese language referred to any character or real person that possessed masculine and feminine traits as futanari. This changed in the 1990s, as drawn futanari characters became more popular in anime and manga. Today, the term commonly refers to fictional female or female-looking hermaphrodite characters. Futanari is also used as the term for a specific genre within hentai-related media that depicts such characters.
