From my own personal experience I've heard the white is very popular in Japan. My previous car was a pearl white 2000 Lexus GS300. The person who bought the car buys used cars in the US and ships them back for auction in Japan. He told me (of course after we agreed on price for my car) that he specifically looks for white Lexus because the of name brand, which as someone mentioned earlier - Lexus is or has not been available in Japan, and it's white. [Dang! I should've held out for a lot higher price!]
