Yui Hatano did uncensored after censored and she's still around. I know she's very famous so it helps.
Well there are quite a few more examples of continuing (more than 1 year) censored AV career after uncensored vid, e.g. Akari Asagiri. But sad reality is that most idols who went to uncensored are at the sunset of their career. So a realistic/paranoid fan must always worry about possible retirement/fading/disappearance in the near future.
Sumire Mizukawa debuted almost exactly 2 years ago. Stayed with the top tier of Prestige (ABP) until end of 2017, became freelance. Which might be good or bad. Did Prestige let her go due to poor sale? Or simply a change is good for everyone? She made a few vids for different studios. Then came a strange event. She changed her name without changing status. Under the name Miri Mizuki she made a few more freelance vids. Why drop the established name? Most strange is CJOD made 1 vids with her under each name. So I don't think it's a legal/IP issue about the ownership of the (old) name. It must be a marketing issue. Meaning a fresh unfamiliar name is more marketable than a familiar established name.
I take it as a warning sign. The fandom is fickle. So far 8 vids in 5 months (counting VR) under new name and a uncensored debut with Caribbean. Her earning power might be slipping so her career might go down a few different paths.
It seems to be an above average... even very good vid for uncensored vids. Starts with a nice relaxed conversation in her dressing room, which is neither too timid/shy (come on we know she's no virgin) nor too hurried (even top studios like S1 and Prestige sometimes make vanilla all sex vids too too raw) I don't understand the dialog, but guess the polite greeting very quickly move on to the relevant business, which is trying out a remote control vibrator on her vagina. I really like that she just casually pull up her short pretty-but-no-nonsense skirt and put the vibrator inside her panty. When the guy activate the remote, she was jolted and start skipping and hopping about with pleasure. Hahaha... we all know what we are watching this vid for, we came for the pussy. Not fussy wussy lovemaking, just plain old penis and vagina action. But LOL, it's damngood foreplay watching beautiful Sumire with her skirt pulled up, hopping about with a buzzing bulge in her panty. Next we get back into conversation mode as she sits in a sofa and have a chat with the off screen guy. She seems happy and engaging and relaxed, her laugh is a joy to see (in general Japanese women don't laugh, they giggle in a half-fake half-suppressed manner). The chat gets more happy and pleasurable as the guy activates the vibrator. Finally she undress down to her bra and panty and it's the best sexy 14 minutes of no-nudity scene up to this point. Finally panty came off and she started masturbating with the vibrator. That's it! The moment we have waited for: pussy. Her pussy is pretty dark, not very hairy. I think I'd rate it an 8 out of 10.
Scene 2: a more typical uncensored scene, the guy finger fucked her. I didn't see a splash (it's fine, I don't want to see pussy gush so much), but he shows her his wet fingers after he finished, supposed to mean she did ejaculate. And finally the bra came off and he plays with her tits. Then we get on to the usual sequence: kissing sucking fucking. The cock isn't huge but a good size. It's so so satisfying to watch a beautiful idol sucking/fucking a nice erect cock instead of mosaics. The sex is pretty good, with varied positions and well-captured by the camera. (i.e. no extreme close-up of reproductive organs). When the guy came, he pulled out of her pussy and shoot into her open mouth, then she takes off grabbing the cock by both hands and play with it with her sperm-filled mouth and fingers. The cumshot is both unremarkable and very enjoyable very sexy. At this point I would have preferred if she just swallow the load. And it seems like it's already well on its way down her throat when she made some effort to push the sperm back up and have to show the camera and finally spit it into her hands. Quite unnecessary, because it's uncensored, we saw the squirts coming out and entering her mouth. Just let it go down, nice and easy.
