Those top soaplands only have true Japanese girls, no worries.
Service will also be top notch not only from the girls but also the service boys from the moment they fetch you from the closest subway station to the moment you leave.

Soaplands allow full service. It s the only legal place where full service or "penetrative" as you say is allowed in Japan.

Expect not only full service but nuru nuru and also rimming. Usually these premium soaplands will allow multiple shots within the agreed time frame.

If you have the bucks, definitely go for it, but after that you ll find service horrible whether it is Macau saunas, German Fkks or Hong Kong walk ups.
