On Sunday, officers took the 32-year-old Chinese manager of aesthetic salon Cosmos into custody for providing sexual services to customers in private rooms in violation of the Law Regulating Adult Entertainment Businesses.
Two female masseuses were also arrested for violating a prefectural ordinance regarding prohibited business practices.
The manager has reportedly admitted to the allegations.
The shop was warned by law enforcement in the early morning hours of September 22 and November 2 but did not modify its business practices.
According to Yomiuri Television (Nov. 3), police suspect that a number of shops are offering illegal services, and are administering an ongoing crackdown on those operations.
