Tried this place a few weeks ago. Mamasan shows me a young (probably late 20s) girl, cute with nice teeth and pretty good English, with large top named Yuki (I think). Has large tatts on her ass neck. Paid 80 and on to table shower, then to room, which is COLD, and there's no heater in room. Yuki gives lame rubdown, nothing to remember. During massage, I am rubbing her leg, making clear what I am there for. Flip, I go for the top and she is almost completely padded upstairs; no more than an A-cup under her fortress of a bra. Starts mechanical hj, no eye contact, no smiling. I push for bj, no dice. End up calling off the hj and just finish the lousy massage (since I had so much time left).
If they have other girls who give better service, this could be a place to check out when the weather warms up (it was seriously cold in the massage room) because the facility is very nice and there is a private shower in the massage room. Not sure mongers are going to make much use of the pool (and be seen be fellow mongers), but it's there if you want it. Of course, I would trade any and all amenities for a masseuse who gives blow jobs.
