In the 2008, Japan got a Pepsi White, but it was yogurt flavored. This year's Pepsi White flavor, however, is "Snow Mikan" and hits on this December. Mikan are traditionally eaten during winter in Japan, and they are very much a winter food. Snow Mikan Pepsi, however, is no traditional drink-not in Japan or anywhere else!
