Of course GFM, I wouldnt just search for J girls!
Id be looking for
Japanese
Sushi
For example, both of which I have tried before with good results.
Or trying some "Japanese" style names. Reiko, Nana, Yoko that kind of thing.
The next IQ level would be to look at shops surrounding the area i usually frequent (lets say Ginza for the OP) and check rosters for advertised girls.
Then, once a few have caught my eye (lets say I like Elika from SBM) then I either search that name, or search prefix SBM and see if I can find any reviews. Or finding good AR on a girl then checking what shop she is in, and working out she is close to another shop I like for example
So ok, I do understand this takes time and multiple clicks or taps, and its much easier to simply post up "Best thing with holes in the world?" To save myself that time, and see what happens.
But the fact of the matter is, 99% of the info you need is right there in After Reports, which everyone has access to immediately.
Not trying to be a dick, just saying, use some initiative. Im a bit harder on this guy also because he isnt a completely new member.
