http://www.lizadalby.com/Geisha%20tea-eyes.html <-- a page by the woman who was hired as a consult for the movie, it has some info on why the movie was as american as it was (besides the obvious bit of that it was made by Americans, based on an American book), rather than actually having more genuine geisha details. The woman has actually gotten some Geisha training, which is what the page is about.
