Japanese police have arrested the alleged ringleader of a sex home-delivery service specialising in women weighing up to 150 kilograms (330 lbs), a spokesman said.
Keiko Saito, 41, and one of her employees are suspected of conspiring to run a prostitution business under the name "Makkusu Bodi" (Max Body), which boasted that it catered for men who like "explosive boobs and bums", police said.
Saito is alleged to have had about 30 overweight women working for her, including one who tipped the scales at more than 150 kilograms, Jiji Press reported.
Police say punters in Tokyo could telephone to request a visit in their home or hotel room, a service called "deri-heru" (delivery health) that is widespread in Japan, where it is illegal to sell penetrative sex.
Saito, who is believed to have earned about 400 million yen ($4 million) over three years, had previously worked as a prostitute, Jiji said. She began her business because she believed larger women were popular with customers, the agency added.
