A fundoshi in practical application.

The fundoshi (Japanese: 褌 / ふんどし) is the traditional Japanese style of Loincloth. It is a single long piece of cloth wrapped into place and fastened by twisting and tucking alone. This versatile tying technique makes any suitable piece of cloth a potential fundoshi. A similar technique can also be used to wear cloth as a headband. Although historically worn by both men and women, if worn by women in modern fiction, it is almost always for fanservice.

Traditionally, the fundoshi was worn as a form of underwear. Its role as underwear has decreased in modern Japanese society, as more people wear Western-style underpants. The fundoshi still may be worn during traditional festivals, or as swimwear. In fiction, it will often be worn constantly to complete a Japanese set of Awesome Anachronistic Apparel.

A Sub-Trope of Loincloth. Compare Barely-There Swimwear, Sexy Sweater Girl, Sexy Soaked Shirt. Not to be confused with fujoshi or their male counterpart fudanshi.

    Anime & Manga 
  • Matsuri of Ayakashi Triangle wears fundoshi, which we end up seeing a lot after he's turned female. His name is even a a pun on this, being a homophone for the matsuri (festivals) where people still wear them. According to a bonus page, it's considered part of the exorcist Ninja uniform, but Matsuri wears them even off the job because he's comfortable in them. He also lets Suzu know that his grandpa wears a red fundoshi. This doesn't seem to be as common as Matsuri assumes, as Soga lets him know he just wears boxers. Eventually, Matsuri's mother convinces him to switch to regular panties as a sort of mental endurance training—temporarily causing Matsuri to become less confident and even less coordinated.
