I’ve no idea, but probably? A few years ago (before the pandemic) he used to regularly post photos of him with like generally famous people.
Like this one, for example Yoshiki on Instagram: "What a surprise! President Obama showed up. Having an amazing birthday in SF! サンフランシスコで誕生日に、サプライズでオバマ大統領がきた。。 @barackobama"
Looks like there’s also a thread here about that: Where in The World is Yoshiki? (i’m pretty new here, so I haven’t really read it, though.)
He holds (really expensive) dinner shows in Japan from time to time where he’ll play a few songs on piano and walk around shaking hands with the guests. (I watched one that was livestreamed.) And for some reason, execs from huge companies are invited to them. The one I watched announced these random white people like, “Mister A from [Big Company]” on the mic. No idea if they know who he is or if they just show up to every rich guy function they’re invited to.
