No, no they do not.
While there may be a good deal of fascination with Western culture, the Japanese decidedly do NOT idolize it anywhere close to as much as their own. At best it's given slightly less attention than Korean culture.
No credit for partial answers!
In visual aesthetic terms, Japan is saturated with references to 'Western culture'. There are people in Yoyogi Park who dress up like rockabillies every weekend and have dance-offs like they're in Grease. There are people who dress like 80s British punks. Even supposedly 'Japanese' pop-cultural phenomena tend to draw from Western visual styles, Visual Kei being a prime example. Very little in Japanese visual culture does not draw on Western cultural tropes.
What you're referring to is that Japanese people themselves tend to no longer see these things as 'foreign', they've lost their connection to an outside source or the things they reference. This leads to a bizarre paradox that Japan is extremely culturally insular, while at the same time borrows its visual language almost intact from the West.
There is another thing which bears mentioning though, and that is that there is a slight but observable degree of racial fetishism in Japan. We're talking about a country where eyelid surgery (to put a crease in the eye, which most asian people lack) is a standard beauty treatment, where blonde hair and blue eyes are signs of beauty despite the fact that noone possesses them, where blaxploitation still somehow thrives in the absence of any real (and sizeable) black population. It's not necessarily harmful, like everything else I think it's too robbed of cultural context to be directly offensive to anyone, but it's still kind of distasteful.
