Just my 2 cents, I am sure she wears real furs. There's always the possibility a percentage of them are faux but if you're 1) rich and 2) wear jackets like that, they are almost always going to be real. Japan in comparison to America (i.e. groups like PETA) does not make as big a deal about wearing animal skins/furs. Every winter, it is very easy to purchase rabbit or fox fur accessories for incredibly reasonable prices. It doesn't make her a bad person but I think the habit of owning furs has been villainised.
