Japan handset shipments grew +21% annually in the first quarter of 2012, the country's fastest growth rate in over a year. Sharp continued to decline as Fujitsu and Apple gained traction at two of the big three operators. Indeed, Fujitsu is now the clear no.1 vendor in the high-value Japan market. Meanwhile, Samsung drifted sideways, and Kyocera and Sony maintained their broad upward momentum. This published report -- available to download by clients of our Country Share Tracker (CST) service -- tracks handset vendor marketshare by quarter at all major operators in Japan, including NTT Docomo, Softbank and KDDI. The report can be used by handset vendors, component makers, content developers, vehicle manufacturers and others to identify winners and losers by carrier in the high-value Japanese mobile market.
