I'm pretty sure he stopped playing it on the regular when Sega stopped doing their Star Player program, which was in 2014 or so? (Sega has been sponsoring players in VF for the better part of 20 years -- it's crazy how ahead of the curve they were with this). He did come to the US for Sega Cup 2013 and 2014 and took everyone's money then, so he was still actively playing then.
I actually got to play him at Sega Cup 2013 and I got bodied. Even playing someone like Itabashi Zangief, it at least felt like I could try to do things and make adjustments (even if I got outplayed most of the time), but playing Fuudo felt like playing a robot specifically designed to just crush people's existences in videogames.
Moral of this story: He's freakishly good in a number of games in a way almost no one else is. Don't forget his multiple national titles in Gunslinger Stratos or his Kaidan rank in Beatmania IIDX.
