History HotSpringsEpisode / AnimeAndManga

* ''Anime/{{Gintama}}'' has this on episodes 131 to 134 as Stand Arc where the Yorozuya and Otae-san took on a vacation and zany misadventure about spiri... stands.
** Then on Episodes 219-B and 220, Gintoki, Shinpachi, and the Shinsengumi are on this trope, now with Hedoro and his family. Hilarity ensues.

* ''Anime/TheWallflower'' had an episode set in a hot spring, which featured a murder mystery, Sunako generally creeping out everyone staying at their hotel, and a truly awe-inspiring [[https://www.youtube.com/watch?v=qOE04nchmv0 game of ping pong.]]

* In ''Anime/YuriOnIce'', Yūri Katsuki's family runs a day trip onsen ryokan called Yūtopia which also runs a teahouse and served as a part of the setting in early episodes. Unsurprisingly, nude fanservice runs rather rampant, albeit coming from the male side of the bath (mostly coming courtesy of Viktor).

* ''Anime/GinTama'' has this on episodes 131 to 134 as Stand Arc where the Yorozuya and Otae-san took on a vacation and zany misadventure about spiri... stands.

* In ''Webcomic/HetaliaAxisPowers'', Japan has a small hot spring in his BigFancyHouse. Both in the manga and the anime, England gets to enjoy the warm water -- and befriend some spirits, like a ''kappa'' and a ''zashiki warashi''. [[TearJerker Who have to leave the house since Japan can't see them anymore]].
** In the manga... how does North Italy find out that Japan's a lightweight [[GagPenis in his pants]]? When they both take a bath in the same spring.

* ''Manga/GetBackers'' has two. One involves Ban and Ginji mistaking Kazuki for a girl at a distance and trying to peep on him, Juubei and Kazuki cranking up the HoY. The other involves Shido proving that his girlfriend Madoka has him whipped, Ban and Ginji being ''very'' intimidated by the size of Shido's... [[GagPenis um...]] and monkeys. Again.

* Early on, ''Manga/NegimaMagisterNegiMagi'' involves quite a bit of action in the pool-sized bath, although not ''that'' kind of action. It dies down until a "Chapter 100% in the nude" appears as a break involving hot springs.

* ''Manga/OnePiece'': At the end of Arabasta arc, although the fanservice there is strictly for females. When Nami catches the guys peeking on her and Vivi, she gets rid of them by flashing them, causing them to pass out and fall back on their own side. She dubs this technique the "Happiness Punch" or "Paradise Punch", depending on the version.

* Episode 20 of ''Anime/Persona4TheAnimation''.

* Episode 5 of ''Manga/{{Saki}}'' has the characters going to one for their Mahjong training camp.

* ''Anime/{{Gravion}}'', naturally, has a Hot Springs Resort episode, and naturally (being ''Gravion''), it still ends with a {{Robeast)) battle in molten magma while the maids sing Gravion's transformation theme.

* ''[[Franchise/LyricalNanoha Magical Girl Lyrical Nanoha]]'': The cast goes to a Hot Springs or [[PublicBathhouseScene Public Bath]] together once per season. The FanService-oriented first season had this occur in the anime itself. The later two seasons relegated these episodes to the [[AudioAdaptation Sound Stages]]. The ''[[Manga/MagicalGirlLyricalNanohaViVid ViVid]]'' manga also features one (with extra fanservice).

* ''LightNovel/NananasBuriedTreasure'' has a rare gender-swap of [[Administrivia/SeenItAMillionTimes what almost always transpires]] in hot spring episodes. Yuu gets excited by the [[InnocentInnuendo increasingly homoerotic]] conversations going on in the ''men's'' section, and she eventually pokes a hole in the wall to peek at them. She doesn't get to see much of her beloved Isshin, though, so she [[UnprovokedPervertPayback jabs Juugo in the eye for no reason.]]

* Episode 6 of ''LightNovel/DateALive'' is dedicated to everybody trying to get ''to'' the hot spring, only to face obstacles on the way. When they finally make it, [[AnIcePerson Yoshino]] accidentally freezes it solid. Fortunately, Kannazuki, who had been ordered to dig a massive hole as punishment at the beginning of the episode, uncovers a geyser, and they convert that into an onsen.

* In ''LightNovel/TheFamiliarOfZero'', a hot spring erupts on Saito and Louise's land. Saito quickly converts it into an onsen and invites everybody to use it. Several characters had never heard of a hot spring, but agree to come when it is explained, and the girls like how it is good for the skin. They agree to have the boys and girls take turns, but the boys (except for Saito) predictably try to peep, only to be [[CantBatheWithoutAWeapon blasted away]]. Tiffania faints from the heat and has to be carried out. Later that night, Saito and Louise [[TwoPersonPoolParty use the onsen together]].

** There was also a bit of one in the original ''LightNovel/FullMetalPanic'' in the bath on the ''[=TdD=]''.

* ''LightNovel/NyarukoCrawlingWithLove'' subverted this during the UsefulNotes/AdobeFlash-animated ''Remember my Love(craft)'' series, teasing a Hot Springs Episode in the NextEpisodePreview, then spending the entire running time with a shot of Nyarko's pet Shanta-while we just hear the female cast talking to one another. At one point Ato-ko says "[[LampshadeHanging I feel kind of bad about teasing the audience like this...]]"

* ''Anime/{{Patlabor}}'' :

* ''LightNovel/ShakuganNoShana'' had the Hot Springs OVA. There was also a pool episode, but it probably doesn't count (although that one has high doses of fanservice).

* ''LightNovel/{{Sukisho}}'': The last episode. Taking into consideration that it is more or less filler it is not surprising that fanservice should abound.

** The second episode of ''[[LightNovel/WashioSumiIsAHero Washio Sumi Chapter]]'' contains a scene where the girls are in a hot spring after training.

* Not in the series proper, but the OVA episode "Vacation" for ''LightNovel/AccelWorld'' centered around Haruyuki's friends taking him to a hot spring to help him lose weight for an upcoming physical exam. The place serves for a bit of soul searching for both him and his girlfriend Kuroyukihime. In playing with the series's rules, there also exists a virtual counterpart to the hot springs in the Accelerated World, which the characters take a dip in as their avatars.

** Another episode involved [[VillainProtagonist Keroro]] [[RagtagBunchOfMisfits and his platoon]] trying to drill their own hot spring so they can get rich off of it. Though, much like the rest of [[FailureIsTheOnlyOption Keroro's schemes]], [[MurphysLaw things]] [[GoneHorriblyWrong go]] [[DidntThinkThisThrough south]] [[HilarityEnsues very quickly]].

* The ''Manga/RurouniKenshin'' anime has not one, but two onsen episodes. Both involving characters accidentally seeing each other naked.

** The third episode of the Unova Saga is one. Right after Ash received his Oshawott, he and Iris intend to do a sand bath, only for them to later find out that the sand will be flooded by hot geyser. The sand bath house becomes a hot springs house in the end. And Ash meets the Sunglasses Sandile that would be caught by him 61 episodes later.

* In ''Anime/YuriOnIce'', Yūri Katsuki's family runs a day trip onsen facility called Yūtopia which served as a part of the setting in early episodes. Unsurprisingly, nude fanservice runs rather rampant, albeit coming from the male side of the bath (mostly coming courtesy of Viktor).

* In ''Anime/YuriOnIce'', Yuri Katsuki's family runs an onsen facility called Yutopia which serves as a part of the setting in early episodes. Unsurprisingly, fanservice runs rampant, albeit coming from the male side of the bath (mostly coming courtesy of Viktor).

** And then there's the Lavaridge Gym battle between Sapphire and Flannery -- yes, a Gym battle in a hot spring. Sapphire wanted to do it right then and there, however; Flannery and Mack used their strongest fire powers to slow down Mt. Chimney's complete death after Team Aqua killed the volcano, and it was now or never for the hot springs.

* ''Manga/AiKora'': Played for laughs and {{lampshaded}} in the same chapter, when Hachibe invites all the girls along with him to an onsen he "won" tickets for (he really worked at a bunch of several part time jobs to earn the money to buy them, unsurprisingly.) simply so he can talk to Sakurako and figure out his feelings for her and vice versa, and also to peek at the girls of course.

* ''Manga/BlackClover'' has a four chapter/two episode mini-arc about this. Most of it is spent just ''getting'' to the hot spring, which is a reward for a training exercise that involves ''climbing a magically super-active volcano.'' [[DrillSergeantNasty Mereoleona]] apparently intended the mixed-gender group to all bathe together (to everyone else's discomfort) before [[DishingOutDirt Sol creates a wall]] to divide the pool in half. Also worth noting is that none of the guys are interested in peeking until Yami talks them into it, and seems more interested in watching ''them'' try than doing it himself. Yuno remains disinterested, though, while Asta refuses out of principle. The anime episode based on this chapter even ends with the words "So ends the obligatory hot springs episode".

and rocks, fences and shampoo bottles [[SceneryCensor placed oh-so strategically]].''\\

** There is another one in chapter 261 with Lucy, Erza, Wendy, Levy and Juvia. Natsu, Gray, Jet and Droy try to do some OutdoorBathPeeping. This was initially omitted from the TV anime but was instead made as the fourth OVA where the fanservice was increased.
** There's another at the end of the Sun Village arc. Interestingly this one is unisex with Lucy and Wendy embarassed (Erza doesn't really seem to care) until they notice the guys aren't checking them out at all. They point out that thanks to their usual wacky antics they've accidentally seen them naked so many times the novelty is gone, and they proceed to enjoy their bath together without any incident (unless you count Natsu beating up Erza by accident).
* In ''LightNovel/TheFamiliarOfZero'', a hot spring erupts on Saito and Louise's land. Saito quickly converts it into a onsen and invites everybody to use it. Several characters had never heard of a hot spring, but agree to come when it is explained, and the girls like how it is good for the skin. They agree to have the boys and girls take turns, but the boys (except for Saito) predictably try to peep, only to be [[CantBatheWithoutAWeapon blasted away]]. Tiffania faints from the heat and has to be carried out. Later that night, Saito and Louise [[TwoPersonPoolParty use the onsen together]].
* ''Manga/FruitsBasket'' has an episode where Kyo, Tohru, Momiji and Yuki visit the hot springs resort owned by the Sohma family. Not as much fanservice for guys, but a fair amount for the female audience.
* ''Anime/FullMetalPanicFumoffu''. Episode 9, alternatively titled "The Hot Springs Episode", is a direct parody of the hot springs cliché (among others), and features three male characters trying to infiltrate a women's bath, fully protected by a steel wall between the male and female sides to prevent peeking, sentry guns and mines.

* Episode 19 of ''Anime/TheGalaxyRailways'' has the members of Sirius, Spica, and Vega platoons vacationing at a Hot Springs ouned by Captain Murase's parents.

** Then on Episodes 219-B and 220, Gintoki, Shinpachi and the Shinsengumi are on this trope, now with Hedoro and his family. Hilarity ensues.
* The one in ''Manga/GirlsBravo'' takes place in episode 11, when Yukinari, Kirie, and Koyomi take a trip in the countryside. Except [[AbhorrentAdmirer Fukuyama]] and [[CuteAndPsycho his sister, Lisa]], decide to follow them. So their peaceful trip turns into a ping pong match between Kirie and Fukuyama to decide whether they got the boot, or if Kirie would have to [[spoiler: use her naked body as a loofah to wash Fukuyama's back]], if she lost.

* ''[[VideoGame/HarukanaruTokiNoNakaDe Harukanaru Toki no Naka de 3]]'': There's a short [[SuperDeformed "chibi"]] anime special for that takes place at a hot spring.

* Second season of ''Manga/JunjouRomantica'' has Usagi and Misaki vacationing at a onsen, where they unfortunately meet Usagi' father Akihiko.

* ''Manga/{{Mahoromatic}}'': In hot spring issue of the manga the [[OutdoorBathPeeping typical gender roles usually inherent with this trope]] are inverted. Miss Shikijou encourages the other girls to spy on the boys' side. The flimsy dividing wall collapses when they try, and they all scatter, whooping and laughing.

** And while they're vacationing on Okino Island, the girls decide to bathe at an outdoor spring...without the guys. But the two of them escape and try to make in time [[OutdoorBathPeeping to see some some eye candy.]] It then becomes a test of their determination, as they try to get past [[TheGadfly Yuuka's]] traps, to reach the spring before the girls are finished bathing.

* ''Anime/MazingerZ'': In chapter 8 of the original manga, Kouji and his friends spending a while on a hot springs resort in a mountain. That episode was noteworthy because Mazinger-Z did not show up and it had a very funny Kouji/Sayaka moment in the hot springs (with a double LuminescentBlush included).

* ''Manga/MonsterMusume'' has a hot springs chapter when the main characters go test out a new hot spring resort that's designed to cater to both humans and liminals before it opens (the house was undergoing some repairs at the time anyway). Due to how fan-service driven the series is to begin with, the chapter doesn't stand out in that regard.
* ''Manga/MyBrothersHusband'' has Chapter 16, where Kana insists on visiting an onsen with her uncle Mike, and her father Yaichi has to invite her mother Natsuki along so that Kana has a female chaperone at the single-sex baths. What fanservice there is is low key and with the guys as the objects of attention.
* ''Manga/MyMonsterSecret''. Unusually for this trope, almost all the chapters involving it are set in the ''mens'' bath. There's still the obligatory fanservice, courtesy of [[LovableSexManiac Shiho]] showing up for the purposes of training up her "pervert power." This promptly leads to Rin also invading the men's bath to attempt to "seal" said pervert power.

** In another, the cast stops by a resort on the way back from a long plot arc. LovableSexManiac Jiraiya immediately heads for the springs to take advantage of all the {{Fanservice}}. The females, in a moment of clarity decide to spend their time in the casino rather than the water. While the plot unfolds we are treated to repeated cutaways of Jiraiya sharing the water with monkeys, Sumo Wrestlers, and elderly old women. By the time the young women show up, Jiraiya has been in the hot water so long he's passed out from heat stroke.

* ''Anime/NatsuiroKiseki'' has one with four fourteen year-old girls, no towels and a lot of [[CensorSteam censor steam]].

** The third episode of the Unova Saga is one. Right after Ash received his Oshawott, he and Iris intend to do a sand bath, only for them to later find lout that the sand will be flooded by hot geyser. The sand bath house becomes a hot springs house in the end. And Ash meets the Sunglasses Sandile that would be caught by him 61 episodes later.

* In ''Manga/Reborn2004'' they play the cheap version in when Dino's pet turtle destroys their bath tub. (and most of the house)

* ''Manga/SayonaraZetsubouSensei'' has an episode in which the gang decides to detox at a hot springs facility. Fanservice is mocked, the class of highly problematic students end up losing their quirks and becoming normal... leading Itoshiki to re-tox them with highly caloric food. He then gets pushed onto the de-toxing spring himself, then dramatically disappears. He was ''all'' toxins.
** For bonus points, count how many times [[{{Invisibility}} Kagero Usui]] can be seen on the girls side, mostly unnoticed by even the viewers. At one point, there are several Kagero Usuis all over the fence.

* Just about ''every'' episode in ''all'' the ''Anime/TenchiMuyo'' series have at least one scene in an onsen. The first TV series has [[MadScientist Washu]] build one into a PocketDimension attached to the bathroom - a woman opens the door, and enters an opulent onsen with steaming water fountains. A man opening the door just enters the normal bathroom. ''Ryoko'' builds the onsen in ''Tenchi Muyo! Ryo-Ohki''. Lacking Washu's ubertech (or at least, lacking Washu's ability to invent new ubertech on a moment's notice), she just built a FloatingIsland behind the house and put the onsen there.
** The OVA had two episodes actually ''dedicated'' to the place: Episode 4, which served to introduce Mihoshi to the cast, and Episode 9, which served as not only a sequel to episode 4, but also dedicated itself to Sasami's backstory.

* ''Anime/ZombielandSaga'' features such an episode, and ruthlessly parodies the entire concept. Franchouchou is hired to perform at a company retreat, and get to stay at the inn as a bonus. Their manager strictly forbids them from going to the baths, so naturally several of the girls sneak out for a late-night dip without their makeup. Instead of losing their towels or other fanservice tropes, Sakura loses her head in the bath and leave a company executive traumatized over encountering the undead at a "haunted" inn.
