Ok right it's right there in point 6, my fault not bothering to pinpoint the ref.
But what's point 7? It's saying absolutely nothing. Until 5 years she has no right NOT to allow circulation, after 5 years she said nothing to say she will delist her vids. It's not the regular Japanese word art of meaning something by saying something else. Here point 7 is really nothing, unless I'm missing something lost in translation.
As for your remaining remarks, it's based on nothing and saying nothing. Did she say she is going to mainstream media? I don't see it anywhere. It's yet another trademark jwlim hot air. Keeping herself listed on AV agency is actually implying she's not striding out to non-AV opportunities. If I guess, I'd guess she will be no more than doing a few hours of work (meet and greet etc) per month, even zero. And the income would probably not cover her afternoon snacking. There's even a good chance she won't do any more actual work with the agency and only allow her name to stay on the roster because the agency want to use her name to recruit new girls. Anyway all is speculation yours is no better than mine and no better than saying nothing. I won't mind discussing possibilities but your tone is trying to be authoritative but actually is unsupported.
Seem to me she is the intelligent and careful and wise type. She has been thinking about it and have a solid plan. If she told nothing about the plan to AV fandom I take it to mean there is actually a plan, and a solid sensible plan that doesn't involve sex (e.g. working the hostess scene). Which is exactly not "leveraging her fame". Nor do I see anything that says she need to or want to erase her AV career.
The one thing that she said that makes no sense to me is point 10. Sure a farewell gravue book makes excellent business and sentimental sense. But crowdfunding? That's out of left field. I wonder if it's the amateur interviewer injecting something unneeded and unworthy.
Finally your line "reporting saying the younger generation of AV fans finding her a has-been." Based on your past records, I won't bother with it until you post the original source.
What about the point about wanting to produce work that are outside of adult nature :-
"引退後は色んなプロデュースやアダルト以外のお仕事を精力的にやっていきたい"
And the original Japanese text states that she is only "graduating" and not "retiring". Join the dots and make your connection. For me it's clear she's making a break for mainstream.
As for her popularity, there's no official poll, it's just a popular opinion on BBS that came out every now and then and here's one in chinese that you can understand :-

Look at how many times the name Yoshizawa turns up.

It's human nature essentially, everybody wants the newest shiniest things, not something that dates back a decade or more.
