I had a talk with few friends who know the field very well and they have talked with many customers [ and not only] in the last 10 years.
Ginza [and two other shops are very close] has the perfect model on rates and tiers / quality control. From 250$ to 300$ for an hour [and with a such a good balance for the 30 and 45 minutes] with the service to include ... dfk, daty, fiv, bbbj, cim, fs. - The 250$ to 290$ for an hour is the range of rate that will stay for long because is the right rate and business like Ginza know.
So, keep this as a guide and don't leave few 'houses of love' or massage shops or ml to fool you, unless you want.

Personal I say no to the shops that have the same rate for all the wl's [ I want tiers] because is impossible [we are humans, equal but all different] all the wl to have the same attitude / willing / energy / beauty / body.
Tiers exist for to help the healthy competition and also to help the customer to decide.

Also, there are many ml's out there who fool people with the tips and few of these customers they accept it.
How is possible a customer to pay in a massage shop [in total] the same money or more than he pays at Ginza for less or similar service?

Enjoy!!!
