Android and Apple dominate the smartphone market in Japan just as they do elsewhere in the world.
Looking at Japanese smartphone ownership in the three months ending June, ComScore found that Android took home the lion's share with a 64 percent share, up almost two points from the prior three months. Apple's iOS grabbed a 32 percent share.
That left Microsoft's Windows Phone in third place with 3 percent of the Japanese market. RIM's BlackBerry OS and Nokia's Symbian combined eked out less than half a percentage point.
More than 25 million Japanese consumers owned smartphones during the June quarter, around 23.5 percent of all mobile users. Smartphone ownership in Japan has jumped 43 percent so far this year, ComScore noted.
Among mobile phone makers, Sharp scored the top spot in Japan with 22.6 percent of the market. In second place was Panasonic with 13.6 percent, followed by Fujitsu with 11.8 percent, NEC with 8.9 percent, and Sony with 7.9 percent.
For the June quarter, 102.7 million Japanese 13 and older used mobile phones (smartphones and feature phones). To compile its results, ComScore surveyed more than 4,000 mobile subscribers in Japan.
