"It's deemed likely that Apple had the top-selling cellphone in Japan this past fall, but how did it do in all of 2011? Quite well, if you go by MMRI's estimates. The iPhone had 30 percent (almost 7.3 million) of the Land of the Rising Sun's 24.2 million sales among individual smartphone labels, or nearly double Sharp's 17.5 percent. Don't think that Android-powered smartphones like the Aquos SH-12C didn't make an impact, though: virtually every other smartphone in Japan, 69 percent, was running some flavor of Google's mobile OS. Apple managed to shake up a sometimes insular overall keitai market as well, having come just short of Fujitsu for the top spot in all cellphones. Researchers are expecting the smartphone space in Japan to grow by a healthy 15 percent in 2012, although it's still a wildcard as to whether or not KDDI's iPhone support will keep Apple riding high for another year."
Note: in the article the pie chart on the left is smart phone sales which shows Apple as the top dog, the pie chart on the right is overall mobile handset sales which shows Apple as #2: 0.9% behind Fujitsu.

Anyway, I'll tell you why the iPhone sold so many units here. It's the same reason I got mine. ¥6k per month on softbank for unlimited data and free calls during the day. Oh, and the iPhone was totally free.
Most people with an iPhone also have a phone on Docomo for better coverage and 10-key ease-of-use mailing.
I'm getting rid of my iPhone tomorrow though; bought myself something different
