Maybe, kinda luxury... My local supermarkets also sell salad dressings and other packaged goods with famous hotel branding. And department stores sell very banal house furnishings with logos from celebrated designers on them. Those brands wouldn't risk allowing their logos to go on such products in Europe for fear of diluting the cachet that they worked so hard to associate with their brands. For Japanese consumers, a logo evidently matters but Pierre Cardin house slippers don't seem to be priced any higher than Playboy ones ... (At least that's my recollection from the last time that I looked at house slippers in a department store, which was many years ago).

There's a weird blurring of dross and de-luxe. I think it would be interesting to dig into Japanese perceptions of those products and brands.
