OK boys: this is not a scam. This is just how it works for these folks. Has been going on for years, the chicks in the pix are invariably JAV stars, and the actual supply crew are invariably mainland chinese, sometimes Thai, Burmese, Cambodian or Vietnamese. You will never get the girl in the PIX and they never use the pix of the actual crew. They are not students but usually here on a tourist visa but 'working'. English language is limited, usually very limited. Sex action is varied, usually poor. And it is usually cheap. You don't do for these period, unless you desperately need to blow a load for £80-100.
The managers are usually mainland chinese fixers. Japan and China have a hatred for each other historically they always pretend they are 'japanese'. Try any London oriental agency and it would be the same....
