Mixed bathing
Mixed bathing denotes the shared use of bathing facilities, such as hot springs, pools, or beaches, by individuals of both sexes, frequently involving nudity or scant attire in line with prevailing cultural conventions.[1][2]
Historically, the practice was widespread in ancient Roman public baths prior to Emperor Hadrian's edict circa 117-138 AD, which enforced sex separation via designated times or compartments primarily to safeguard women from harassment in these intimate settings.[3]
In Japan, termed konyoku, it originated as a communal ritual possibly predating the 9th century, integral to spiritual and hygienic traditions, yet it waned from the 19th century onward under Western moral influences and post-World War II regulations curbing new mixed facilities.[1][4]
Western societies, particularly during the Victorian era, largely rejected nude or minimally attired mixed bathing due to heightened sensibilities around propriety and gender mingling, favoring segregation while permitting supervised co-ed swimming at beaches with evolving swimsuit mandates to mitigate indecency concerns.[5][6]
Though persisting in select rural Japanese onsen and certain European spa cultures, mixed bathing today often entails swimsuits in public venues, reflecting enduring tensions between communal utility, personal modesty, and risks of misconduct such as unauthorized photography or overt sexualization.[1][7]
