Omorashi (おもらし / オモラシ / お漏らし), sometimes abbreviated as simply "omo", is a form of
fetish subculture originating and predominately recognized in Japan, in which participants experience
arousal from having a full
bladder or wetting themselves, or from seeing someone else experiencing a full bladder or wetting themselves. Outside Japan, it is not usually distinguished from urolagnia, though they are different things.
Westerners who do make the distinction commonly use phrases such as "
bladder desperation" or "
panty wetting", although a number of fetishist communities in the West have also adopted the more specific Japanese language terminology. The term "omorashi" means "to wet oneself", literally translated, "leaking". The word is also occasionally
romanized as "
omorasi" in the
Kunrei-shiki romanization system.
One of the variations is known as
omorashi yagai, which translates as "to wet oneself outdoors (or publicly)." A further variation includes
yagai hōnyō, or "outdoor (or public) urination", in which the subject publicly removes their clothes to urinate. Other
yagai hōnyō practitioners operate much like
graffiti artists, attempting public urination acts without being caught.

Japanese-produced omorashi media also include
comic books and
cartoons. These range from independently produced
dōjinshi to large, commercially-produced
manga. Some focus exclusively on omorashi stories, while others include only the occasional scene. Some contain obvious sexual themes and could be considered a form of
H manga, while others, like
Iinari! Aibure-shon, are well known to be suitable for all ages, since they have only mild
ecchi content such as
panchira.
[7] Omorashi manga may also adopt the formula of an existing genre while shifting the focus towards wetting scenarios, as in
Omujo! Omutsu Joshi, which follows the typical
Harem formula but features teenage characters who wet their panties and wear diapers.
Wetting scenes have existed in anime as early as the popular
Doraemon and
Devilman series of the 1970s.
However, these did not have the erotic context which characterizes modern omorashi media, since they predated the first full-blown anime pornography, which was not available until 1984, when the advent of the first
H anime OVAs such as Wonder Kids'
Lolita Anime were made possible by the widespread availability of
home video. One example of this later erotic context is the 1994
H anime OVA Vixens, which features scenes of incontinence in a setting that is overtly sexual.
There are also sites where users can upload and watch their own pictures. It can be fanart or manga. Sometimes there are GIFs involved. The most known site for such fanart is omorashi.org. Those pictures are more likely the fanart of already existing anime or game characters (SAO or Touhou), but there are some own pictures too.
An
eroge (
erotic
game) is a Japanese
video or computer game that features erotic content, usually in the form of
anime-style artwork. The crossover of omorashi and anime fandom has produced a number of games such as
Water Closet: The Forbidden Chamber which are specifically focused on omorashi. The limited popularity of omorashi in the West has prompted a number of programmers in the scene to create
software patches for these Japanese games which translate the on screen text into English.
[8]
Some eroge game designers have capitalized on the omorashi fandom's
niche market by including the occasional wetting scene in their games as a selling point.
MAID iN HEAVEN SuperS,
[9] for example, which contains only a single, diapered wetting scene, was used to spin-off an entire set of collectible figures in various omorashi poses.
[10] These
PVC model figures were created by toy manufacturer Giga Pulse, which is not related to the video company of similar name.
Vice Media has documented an account of an omorashi community existing in the
United States since at least 1970.
[14] Outside Japan omorashi groups sometimes refer to their shared interest as "desperation/wetting" fetishism, often making a distinction between content featuring males and females. In 2018,
People magazine
[15] and the
New York Post[16] reported the use of the English language
portmanteau word "peegasm" among people who practiced "releasing urine after a long period of time" in order to achieve "a stimulation of pelvic nerves" that "could feel like an orgasmic response." Some English language fetish websites with a focus on females simply identify as "panty wetting." Since such sites abandon the "desperation" title which implies an effort not to wet, they are more likely to include nudity, overtly sexual models and situations, as well as purposeful (as opposed to accidental) wetting. There are still communities which focus on the more tame or
softcore aspects of omorashi, which are generally focused on simple wetting in fully or semi-clothed situations without the overtly sexual models and situations. However, this softcore side is more rare in English-speaking communities than the more explicitly sexual omorashi content.
