To sell cams to Japanese it is a science on its own. Most will simply ask the girl to sniff own panties and describe how they smell. Girls may have no idea how to describe the smell of own panties for as long as 10 minutes, the smost skilled can find something to say for 30 seconds on that subject, at best. Also some japanese customers I have, made dozen different accounts to stalk the same girl who no more accepted private from previous nicks, they want to enter in the girl life somewhat, see them while peeing and know all their secrets, which is too much voyeur for a western cam girl.
I tried by translate a cam site in japanese (native, by hand) and adding traltime chat translation to/from japanese, but I failed because you need japanese girls, and these was not easy to hire or manage. Also japanese are very afraid to be caught watching porn, to breach any law (uncensored is illegal there), are privacy paranoids as if ever anyone knew they accessed porn (esp. illegal one) they would have to commit suicide for loss of honor (ok here I am joking).
Popular japanese cam sites except the obvious DTI (

About talking: look at a jap-only tube (
http://tokyo-porn-tube.com/ for uncensored, or
http://www.tokyo-tube.com/ for mosaid) and compare clips with a western tube. Western tube vods start with sex, othwerwise users will skip to sex, no one wants to know who the girl is and her life story; instead in japan clips the long blah blah with there's interviews about the whole life of the girl, and only at that point, sex can be performed - they will not want sex with the unknown.
What a sex? Except who just want panties sniffing, the girl will scream like if she's a very young virgin raped, no matter she's old and experienced, it must be dramatic or it is not sex. Even western porn actresses, when hired in Japanese productions, have to learn how to look shy and scream like if raped - and to blah blah about their story for 15 minutes before of any sex.
But the most important issue it is: 95% of japanese will want true japanese girls, no any else; don't give them philipina because "asian", no! They want true japanese girls - to talk with in japanese, about how her panties smell exactly, or her cute life story. Providing a philipina, thai or other asian girl is same bad, as giving a russian blonde, and perhaps they prefer the russian blonde to the philipina or thai, but really they want a japanese girl.
