Tipness day passes?

I'm going to be in Tokyo next month and would like to visit one of the Tipness gyms (they offer a specific fitness class I want to take).

I've been looking everywhere and am unable to find out if they offer a daily rate to just visit a single time.

Any help would be very much appreciated!

I am a member of a Tipness center in Tokyo, but they normally don't offer any visitor rates. They have a one-day trial use (more like a guided tour) for people considering to sign up as a member later, for which you need to show an ID showing your current address, and sometimes they send me a "bring a friend" kind of coupons for special promotions, but not on a continuous basis.
