that's what I was wondering when I first saw the commercials.

Casting controversy
Some people were upset that central characters in the movie were not played by native Japanese actresses, notably that the lead role is played by a Chinese actress.
While many people are offended by the casting, Korean-Canadian actress Sandra Oh advocates inter-Asian acting. In a recent magazine article (Bust Magazine June/July 2005), she defends her roles as characters of Japanese (e.g. Rick) and Chinese descent by pointing out similar behavior from white actors who play European characters interchangeably:
Memoirs of a Geisha (film)
Ralph Fiennes can play an English person, a German person, a Polish person, a Jewish person. He can play anything, and no one questions him. He is a handsome, Caucasian-looking-ish man. So, to American audiences, Europe looks like that. Europe does not look like that. But that is the image we have been fed for 60 years, so we accept that. But what I have big problems with is when people put those limits on me. I just think, "Give me a fu-king break. You have no idea what I am." Because when you meet someone, you never say, "I met Joe Schmoe, and he's Irish-French." But there always has to be a quantifier or qualifier when it comes to me.

Memoirs of a Geisha (film)
Roger Ebert has also pointed out that the film was made by a Japanese-owned company, and that Gong Li and Zhang Ziyi outgross any Japanese actress even in the Japanese box office[1].
In China, the casting of ethnic Chinese actors caused a stir in the Chinese Internet community where some users were unhappy due to rising nationalist sentiment, especially because some mistook geisha for prostitutes. A profession similar to that of the geisha existed in imperial China, whose job it was to entertain male guests with their talents in music, Go, calligraphy, painting and other arts. However, they did not enjoy the status accorded to geisha in Japan. This was exacerbated by the word geigi 芸妓, a Japanese name for geisha used in the Kansai region (Kyoto). The second character 妓 can be understood by some to mean "prostitute", though it actually had a variety of meanings.
