This smells to me... it reminds me of the Nigerian prince scams.  All the scammers need is one or two suckers to take the bite and the scammers have made money.  That's what this looks like to me - all they need is a couple of suckers and they've made a lot of money.

Let's step back a little and reason this out: if you can afford $50K just to get access to their celebrity list, that means you're rich, and so rich that $50K is meaningless to you.  If you're that rich, you can pretty much meet any celebrity you want by giving to their charities and going to the big charity events, investing in movies, etc.  That is, if you're that rich, you don't need an agency like this to meet celebrities.

So, if you don't need this agency, why would you use them unless you're very clueless.  And they probably know this.  That's why they are looking for the clueless suckers...  

Mrfrench, I tend to agree. However, there were a few hints they might be legit.

My interest was in the AV stars because there is no way to book them typically as a non-Japanese.

I emailed them and got a response back from what appears to be an agency in Tokyo, where there are other board posts (not TER) referencing they represent AV stars. That said, they refused to provide any other proof they represented the models before asking a deposit.

Website of the agency is https//tora-ana.jp. Perhaps some members familiar with Japan/Asia have some insight.

Pretty sure it's fake.  Summer doesn't provide. Nor does S.Dee.  I'm fairly confident Jessica Bangkok doesn't either.
