I thought the iphone wasn't selling in Japan:
"Sales of the previous model in Japan reached about 700,000 units, according to Makio Inui, a Tokyo-based analyst at UBS AG. Credit Suisse Group AGs Hitoshi Hayakawa estimates as many as 1 million iPhone 3Gs were sold in the country. Inui and Hayakawa expect sales of the new model in the next 12 months to fall short of those of its predecessor. "
