Futanari (ふたなり) is a Japanese term that appears mainly in anime, manga, and fictional adult media. It describes fictional characters with both traditionally male and female physical traits. The concept is primarily a fantasy or fictional genre rather than a medical classification. Its depiction can vary considerably depending on the story, artwork, or creator. While the term has roots in Japanese language and culture, it has also become recognized internationally through online anime and manga communities. It is important to distinguish futanari as a fictional genre from real-world discussions of biological sex, gender identity, or intersex variations. In popular media, the term is usually used as a storytelling or character-design concept rather than a scientific description.
