Others have already brought it up, but the question is: What is "Western"? And what is "Japanese"? Would colouring my hair black and wearing a kimono make me "asianized"?
The borders between what is what are very thin. Specially in our age. And something that might seem very "Western", might actually have their influence from a completely different culture. It's a process that went on since thousands of years and will go on.
By how maikaru put it so well, wouldn't that mean that most of us on here are "Japanized"? What makes an American "American", a Japanese "Japanese" or a Pole "Polish" anyway? Is someone less "Japanese" by the mere fact of coloured hair or wearing jeans? Are they supposed to wear kimono and carry a katana with them? lol Overall, this is a very delicate topic!!

Like someone already wrote, ayu is more "universal". Take "Endless sorrow" PV, for example. She could have very well put only Japanese people into it, but with various nationalities it went from a domestic to a universal issue. Same with "HEAVEN" and other PVs. I don't think it's the mere fact of being "cool" that plays a role here.

Also, as a side note, it's impossible to colour black hair any darker, right? So all there's left is colouring them a lighter colour. ^^ That's probably all there is to it.
