Google's steady march toward global smartphone dominance scored another major victory, this time in the Land of the Rising Sun. According to new numbers from Tokyo-based analyst group MM Research, Android shot to the top of the mobile OS market share heap, nabbing 57 percent of that country's smartphone market for the last fiscal year. That number is up from 11 percent the year prior, increasing from 250,000 to 4.91 million devices shipped -- it's also a good deal higher than the 37.4 and 38.5 percent that Google commands in the US
, according to recent studies. Apple, meanwhile grabbed second place in Japan at 3.23 million iPhones, according to MM -- or 38 percent of the market -- with Windows Mobile and BlackBerry rounding out the top five. Dessert enthusiasts who don't believe numbers until they see them in pie chart form can check out the graphic after the jump.
