Mmm, is that the same house which is featured in Solomon Palace? If so, I'm pretty sure he doesn't live there anymore. His house now is supposed to be close to the place that Michael Jackson was renting before he died.
Michael Jackson's family house is in the corner of Hayvenhurts Avenue and Libbit street....it's basically a few hundremd metres away of that house in that link.
So yeah, he still lives there and yes, that's the house in Solomon Palace,the Sekai bari bari (or whatever the title was) thingy, another older documentary and every other pic I've seen of Yoshiki in his house in LA....^^;;
As for Extasy studios, I used to have both the addresses from some site but yes, the international one doesn't existed any more.
This one is the address of the recording studios and the one that comes up when you typed 'extasy recording studios' in google maps.
Also, the outside of it was also shown in that bari bari tv show so yeah...it's that one...^^''''
