[[caption-width-right:350:A fundoshi in practical application.]]
The fundoshi (Japanese: 褌 / ふんどし) is the traditional UsefulNotes/{{Japan}}ese style of men's {{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.

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 boxers, briefs, panties, etc. The fundoshi still may be worn during traditional festivals, or as swimwear.

A SubTrope of {{Loincloth}}.

[[folder:Anime & Manga]]
* In ''{{Kenichi the Mightiest Disciple}}'', Shigure and Hayato prefer fundoshi to Western-style bathing suits. Shigure also wears a [[{{Sarashi}} chest wrap]] for her upper body and finds a standard two-piece bathing suit to be indecent.
** Shigure always wears a fundoshi.
* In the ''{{Gokusen}}'' manga, [[ShipperOnDeck Ooshima]] more or less forces Shin to participate in a festival where the men traditionally wear fundoshi, because it's major FetishFuel for [[YakuzaPrincess Kumiko]].
* When [[{{Yotsubato}} Yotsuba!!]] sees someone in a fundoshi at the town festival, she reacts as a five-year-old probably would: "BUTT!! HAHAHAHAHAHAHA!! BUTT!!!"
* In the ''OuranHighSchoolHostClub'' manga, Tamaki must wear one of these if his team loses the sports festival. [[spoiler: They do. He does]]
* Featured often in ''Manga/{{Gintama}}'' for comedic effect.
* Pesche from ''Manga/{{Bleach}}''
** Ikkaku wears one in the "Bleach on the Beach" chapter.
* Another female example: Matabei Gotou from ''LightNovel/HyakkaRyouranSamuraiGirls'' wears this. In her case, it's definitely FanService... (She's not even wearing a skirt or anything over it!).
* Junko's from ''IchibanUshiroNoDaimaou'' is the [[MaleGaze first thing we see of her]]; she also wears a {{Sarashi}}.
* Clain from ''{{Fractale}}'', after being forced to change his dirty pants, reveals that it's his choice of underwear.
* Played for squicky laughs in a OnePiece filler set in Medieval Japan, where Nami is hit by a strange piece of cloth... revealed to be [[HollywoodCyborg Franky's]] Fundoshi. Her reaction is priceless.
* In ''SakigakeOtokojuku'', fundoshi are the only underwear permitted by school rules. Consequently, all the students wear them.
* ''BakiTheGrappler'''s Hanayama Kaoru is a Yakuza, and so a very traditional man. When he gets serious on a fight, he [[BattleStrip rips his clothes]], shows his family's back tattoo and keeps on fighting. [[http://view.thespectrum.net/series/new-grappler-baki-volume-01.html?ch=Volume+04&page=101 Wearing only a fundoshi.]]
* Goemon from ''Characters/LupinIII''. Particularly of note on missions involving swimming or diving; the rest of the Lupin gang will opt for wetsuits, but not the [[{{Samurai}} highly traditional]] Goemon.
* Salamander from ''YondemasuYoAzazelSan'' wears nothing but a fundoshi. It's a ShoutOut to Yukio Mishima (of whom Salamander is a parody of) posing in fundoshi with a sword for a photoshoot.
* In ''Manga/FairyTail'', Elfman wears one adorned with a character meaning "honorable man".
* Kikuri of ''HellGirl'' sports a pair of these. Though considering she looks to be about five years old at best (hard to tell with demons and all) it's definitely not for fanservice.
* ''AsuNoYoichi'': Yoichi in [[http://www.mangafox.com/manga/asu_no_yoichi/v03/c009/12.html his]] show's requisite BeachEpisode.
* In ''Anime/CuteyHoney'', [[DirtyOldMan Dan]][[MiniatureSeniorCitizens bei]] wears one for FanDisservice.
* ''Manga/KyouKaraOreWa'' features it in a rather strange way: a character who [[MuggingTheMonster tried to bully Mitsuhashi pre-series]] ended up bandaged in such a way it looked he was wearing a fundoshi over his head and nicknamed Fundoshi Mask as the start of Mitsuhashi completely ruining his life and [[ButForMeItWasTuesday forgetting about him]].

[[folder:Comic Books]]
* ''Franchise/TheGreenHornet: Year One''. When conducting research for Kato's origin, writer MattWagner was surprised to discover that Japanese underwear of the period essentially consisted of - as he put it - 'banana hammocks'. A scene involving Japanese soldiers in fundoshi ended up in the comic.

[[/folder]]

* ''VideoGame/{{Persona 4}}'' has a fundoshi as armor. [[InformedEquipment Unfortunately, it doesn't appear on their in-game models.]] On the other hand, [[ShadowArchetype Shadow Kanji]] is clad in one when you first confront him.
* Heihachi's 1P costume from ''VideoGame/{{Tekken}} 4''. Enough said....

[[/folder]]

[[folder:Western Animation]]
* ''WesternAnimation/SamuraiJack'' wears a fundoshi under his usual outfit. Since Jack suffers ClothingDamage in half the episodes, he has many, ''many'' fundoshi scenes. This has contributed to making Jack a very potent MrFanservice.

[[folder:Real Life]]
* This is considered traditional in UsefulNotes/{{Japan}} so expect to see it at almost any culture festival that involves men with special outfits. Special [[RatedMForManly manliness]] points go to Hokkaidō men who wear only this ''in the snow'' and the Kurama hi-matsuri (fire festival), where men do this while holding '''20 foot long torches''' on their shoulders.
* Also a pride point for many Yakuza, who loudly proclaim their traditionalist ways. Anytime they pose for their elaborate back tattoos ([[http://en.wikipedia.org/wiki/Irezumi irezumi]]), there is about a 99% chance that they will do it in {{fundoshi}}.
