I first know him not from his music, but from his acting in drama "Akihabara@DEEP" (2006), and I like his character in that drama so much. Didn't expect that I will love his music too. His music somehow always make me feel happy :)
This may sound dumb but in my experience on here, international fans are the ones who do the most for the profile of an act as far as posting pictures, writing a bio, leaving shouts and whatnot. I don't think he has alot of international fans to do all this but he does have alot of Japanese fans on here who listen to him and simply just want to keep a log of their plays it seems.
