[[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.

In the modern world, the fundoshi has been noticed for another quality. The fact that it covers the genitals while leaving almost everything else exposed, has made it a well-acknowledged FetishFuel. It has been adopted as a form of {{Fanservice}}, with a similar effect as BarelyThereSwimwear.

In Japan, this is also less of an issue for the MoralGuardians, as the fundoshi is a well-recognized part of Japanese traditional culture. Thus it is actually in relatively ''better taste'' than a speedo, despite actually [[TheissTitillationTheory exposing more skin]] than a speedo. Outside of Japan, the fundoshi has become increasingly popular as a form of [[RuleOfSexy sexy underwear or fetish wear]] for men.

[[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 ''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.
* In the ''WesternAnimation/{{Gargoyles}}'' spin-off ''ComicBook/BadGuys'', Yama is shown to wear a fundoshi while in stone sleep. It's also hinted from the clothing and equipment neatly laid out on the bed that he often wears an athletic cup.

* Ashitaka from ''Anime/PrincessMononoke'' has a fundoshi as underwear.
* Many of Creator/AkiraKurosawa's movies, being set in medieval Japan, feature men wearing this (and often not much else).

[[folder:Pro Wrestling]]
* Some Japanese professional wrestlers with sexual-charged gimmicks wear a thong or a fundoshi to emphasize it. Otoko Sakari, Manabu Murakami and Razor Ramon RG are examples.

[[folder:Video Games]]
* As a consequence of fandom injokes, Rinnosuke from ''VideoGame/{{Touhou}}'' (particularly his counterpart '''Man'''nosuke) is often depicted wearing nothing but a fundoshi.
* Gotou in ''{{Shin Megami Tensei I}}'' sports a fundoshi despite being a military man. Hell, he will even fight you with only a fundoshi on.
** Speaking of ''Franchise/{{Shin Megami Tensei}}'', several demons such as pre-Soul Hackers Loki and Soul Hacker design Take-Mikazuchi all wear a fundoshi.
** ''{{Persona 4}}'' has a fundoshi as armor. [[InformedEquipment Unfortunately, it doesn't appear on their in-game models.]]
* Heihachi's 1P costume from ''VideoGame/{{Tekken}} 4''. Enough said....
** Also shows up as his Alt costume in ''VideoGame/PlaystationAllStarsBattleRoyale'' [[BeCarefulWhatYouWishFor as a direct response to fan outcry that they wanted his old man appearance.]]
** As one of the swimsuit pieces in {{Tekken Tag Tournament 2}}, most of the men can wear a fundoshi
* Juuichi's fundoshi scene during the camping arc of ''{{Morenatsu}}''. Also, Tatsuki is sometimes seen outdoors in his fundoshi.
* Mizoguchi's alternate costume in ''[[VideoGame/TheKingOfFighters King of Fighters: Maximum Impact 2 Regulation A]]'' is nothing but a fundoshi.
* The Ruan Brothers from ''Outlaws of the Lost Dynasty'' all share the same muscled physique with a rokushaku fundoshi as their base sprite. The only difference is that they put on different colored loincloth and various heads.
* One of [[TheOneGuy Zafira's]] [[AndYourRewardIsClothes unlockable swimsuits]] in ''VideoGame/MagicalGirlLyricalNanohaAsPortable: The Gears of Destiny''. The other one is an OldTimeyBathingSuit.
* ''VideoGame/MarvelVsCapcom2'': Jin's taunt and anti-air animation show he's not afraid to be traditional in more than one way.
* ''VideoGame/BlazBlue''[='=]s Bang Shishigami wears one beneath his outfit, and it's the only clothing that survives his [[FinishingMove Astral]] [[KillItWithFire Heat]].

** Also, in ''{{Way of the Samurai}}'' 3 and 4, you have the option to wear nothing but a fundoshi at the character selection screen.
* Rowen from ''{{Tales of Xillia}}'' wears a fundoshi as his swimsuit costume.

[[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}}.
