i have been trying to have all the JAV ,well known(at least i have known, not those shop claim to be and without the real artist name), as you are seem,

If you talk about A-class and not S-class, there are indeed a few and only handful but not really many in yoshiwara, if lucky pay about 75k as compare to A-class.
I have been trying to have all those 75k in yoshiwara, and they are still only fews and still some don't tak foreigners.
姫川ゆうな i agree belong to A-class, like other

星井笑 they don't take foeriners.
they are only a few, if can really have them , i can say is a very, very good value for money,lucky but is really by chances, cause a lot of the few don't take foreigners.
if talk about JAV fall into A-class or close to, in yoshiware , i would think Kana,mio tokyo rose,Aya misaki tokyo rose,sera Makeup,Risa- tokyo rose,sora hisyo,kirari tokyo rose,rena tokyo rose
AINIA,, AMIRU tokyo rose (they are not my type)can fall into A-Class, but quality wise i think is really can't compare to them
they are good value for the price, though some really can't perform or poor services.
A class they are slightly higher ,2-3 times the price, they take foerigers, and they are those currently new girls on the block, pretty but just new comers, take times and waiting, may potential to become popular or star, if they can make it.
And A-class imortantly, they take foreigners, though the middle man, which is the connection where he make money.
