Tokyo Nightlife Information
The Prostitution Prevention Law prevents any paid sexual full service. However, Soapland lies in the gray area, since they are supposedly renting a place. You pay for the bath (similar to onsen), and coincidentally there was a girl to offer you help! Whatever happens in the room is considered free love. On the other hand, for Deli-Heru, services such as kisses, blow jobs, and sumata are provided. Full service (having sex) is not included in the service, so it will be against the prohibition.
