This is Suzumiya Kotone, who has already retired.
Although she no longer films adult videos, she still works with her agency, Diaz Group. If there's anything different about her appearance, it's that she has many more tattoos:
Having worked with her before and seen her body, I'm pretty sure those were done after her retirement; but I believe everyone understands that many adult video actresses already have tattoos when they're filming, but the industry doesn't like actresses showing those tattoos (because Japanese people think those girls are disobedient and promiscuous), so they either powder them or cover them with tape…
Isn't this common sense? Isn't it insulting to everyone's intelligence to talk about this now?

Yes, but here's the important part. While it's not uncommon for AV actresses to have tattoos, and makeup artists know how to handle them, you might not know that these actresses with tattoos have their salaries deducted by the production company:
How is it deducted? If an actress has a tattoo that must be covered up, she'll likely have around 50,000 yen (approximately 2,800 RMB) deducted. The reason is that the makeup artist has to spend more time covering the tattoo, and that's considered payment. The more tattoos, the more is deducted. What if there are so many tattoos that they can't be covered up?
Then you can only try to find a production company that wants to use you, like Kuon Reira (久远丽罗). But let me remind you, although tattooed actresses were all the rage for a while—Mizumori Midori not only debuted with the top production company Moodyz but also received an invitation to participate in a tattoo exhibition in Taiwan—this tattoo trend has gradually faded.

Of course, some actresses don't do anything about it and just avoid it during filming. However, this is usually discussed during the audition. Given the current high demand and limited availability of roles for actresses, and considering the director's influence during filming, whether or not to cover up tattoos is definitely not up to the actress…
