Just comes down to ignorance is all. Jap bikes are great if that's what you want, quite frankly i don't like vanilla ice cream and I definitely don't like vanilla motorcyles; which is how i would describe my riding experience with honda's.
I personally wanted a Twin, not a 4 banger, and Ducati pretty much makes the best twin so that's that. I might have considered a Jap twin if they made a decent one.
