There are some Japanese models on Western sites, though (or at least their names are Japanese and they look Japanese, so...). One that I found at some point was
Yuna, though she has done very little content (but there is a whole Western site,
Shemale Japan, so...). And out of the more-well-known ones, Serina Tachibana is great, and you can even find
her uncensored shoots as well
Then again, since I think I'm getting used more and more to Japanese faces, even with Japanese people, the guys' faces are almost always have at least some roughness to them, so, with experience, you can still quite often tell that it's a guy*. It's not the same with Thai etc., at least for me (maybe, again, just
not enough experience in this case). But you must have seen
this video, right? The facial features are really feminine there, or at least they pass that mark where you would not really be able to suspect (well, that's why they use the term)
Also, gotta admit that the whole "active shemale" thing has been becoming less and less "appalling" for me, and I now see it more as a fantasy. At least with the Japanese "approach": censored dicks and the overall atmosphere (e.g. calling even big or average ones like that ペニクリ, i.e. "peni-clit", like on the cover below) make the "slide down the rabbit hole" (an innuendo here since it's not the viewer who would be sliding... well, you get what I mean) seem much less "stark"
Not like when a certain comedian described seeing transsexuals in New York (or, at least, in America) in the morning, with all the makeup and fake eyelashes coming off... That's a "glamorized Japanese shemale fantasy" right there. Western shemale porn can be glamorous as well, but I agree with those who say that it's just that the Western she-males are by default more masculine (partly at least because in Japan, gender roles and behaviors are still much more distinct)
(It's NVH-001. The fantasy is also deepened by the clothes of course, the warm lighting, and the fact that her name is Chibitori which can be translated as "tiny bird" or "birdie"... which is, again, in contrast with that... pecker... Oh, a bird sex joke there, nice... I haven't yet watched it, just saw the cover, created that fantasy in my head and saved it for later, but judging by the trailer, they are avoiding showing penetration a lot, and even when they do, they're not as graphic as they could be, to support that fantasy: so that you don't actually see it and can imagine yourself how that would be... Or at least that's how I would interpret it)
* Though I admit that in many cases, like with Tsukimi Suzuka mentioned above, I would still not be able to tell that is't not a "regular" girl; I doubt anyone would
