Hot spring baths or onsens have long been a part of Japanese culture and history, from being used for healing injuries to relaxation, socialization, and leisure. These onsens can be enjoyed individually or by groups. One kind of onsen is the konyoku, a type of onsen where men and women can mingle and soak in the hot springs together. 

The idea of baring all and mingling with someone you know in a bath can be unsettling to some, and even more when it’s strangers and the opposite sex. This is nothing new to someone already familiar with onsen culture. The practice of men and women bathing together has, after all, not been a big deal in ancient times in Japanese history.

Despite this traditional practice, hot spring baths have changed their policies and have allotted time scheduling or separate baths for men and women due to inappropriate behavior among the patrons and the influence and pressure of Western Culture on post-war Japan, and has since been banned in Tokyo. 

It’s not quite as common now but konyokus can still be found around Japan, just fewer in number than it was before. There are some konyokus scattered around Tokyo and here we’ve listed a few that are worth a visit and are just a short trip from the city.
