Japan has about 25% of the global mobile handset market by value

"About 25% of the global cellphone market in terms of cash value is in Japan. - Why? Japanese users want a lot more functions (navigation, mobile payment, QR code, mobile shopping, mobile music and video, mobile TV, ...), and are happy to pay much more per phone. Japan is a totally different game: while NOKIA has about 40% of global market, NOKIA's marketshare in Japan is almost zero."
