If it's not fake, it's been extensively modified. If the guy put those bird inlays in, I'd be a little concerned about the quality of the work, and the Shield on the first fret looks a little dodgy, too, though the pics aren't great. Pickups are definitely wrong. They look like Bill Lawrence knockoffs, definitely not the DiMarzios the D would indicate. The bridge doesn't look right.
I wouldn't touch the thing personally. I see legit Koa JP100Ds on GC in the $499 range pretty regularly.
