The market for delivery health services (as call-girl services are euphemistically known) alone is ¥1.4 trillion. The newspaper describes Japan as a "sex industry superpower" whose growth has been fostered by a "Galapagos-like" legal system.
The Prostitution Prevention Law only covers actual full sexual intercourse between men ...

We recently reported about the large-scale closure of soaplands around Japan following the shuttering of a major chain, possibly to avoid a police crackdown in the wake of the investigation into a major scouting operation that has had far-reaching consequences for the Japanese adult entertainment industry.
And with the closures, it brings to mind a peculiar legal situation for soaplands in Tokyo: according to the regulations governing sex services, you are not allowed to open an establishment in the city, with the exception of a few blocks near Yoshiwara, the old red-light district of Tokyo. ...

It was a rather sad and pitiful end for such a large enterprise. The Marin chain of soaplands came to end on January 30, announced by just a single message on the app LINE.
The chain of around 30 soaplands was run by Morishita Group, a giant in the nightlight and adult services sector in Japan with huge interests in Kabukicho, Shinjuku. This included soaplands in Ikebukuro and Kabukicho, such as the foreigner-friendly soapland Barubola. The Marin Palace (also known as Marin Blue or Marin Mito) was probably the best-known location, renowned for its luxurious-looking and kitsch facilities. It ...

Miporin (Miporin-sama) is known as one of most high-profile dominatrixes in Tokyo. She works for the 11 Channel soapland in Yoshiwara (and claims to be the only latex fetish specialist dom working in that famous district) and the BDSM members' club Dominant Tokyo.
