I've seen Arale at Ginza Club a couple of times now. If you are into petite pocket rockets she's very willing and a lot of fun. Be gentle and you'll have a great time as I did. She's cute with a toned, fit and trim body that obviously gets plenty of gym time. Her English is actually ok, even though the website says otherwise, and I had no trouble communicating with her.
She's in one of the newly renovated rooms at Ginza which I give full marks to as well.
