The value of business carried out through cellphones in Japan was worth more than $140 billion in 2007, according to government figures.
The market, which includes content such as ring tones, as well as website subscriptions and e-commerce purchases carried out through cellphones, was worth ¥11.5 trillion ($143 billion). That's a jump of 23% from 2006, the Ministry of Internal Affairs and Communications said.
The e-commerce part of that was worth ¥7.2 trillion, up 29% on the year, fueled by movie and event ticket sales, travel reservations, air and rail ticket sales, stock trading and online auctions. The mobile-content market grew at a slower pace, expanding 16% to ¥4.2 trillion, the ministry said.
Of six content categories defined by the government, that for high-fidelity music was the largest at ¥1.1 trillion. The market grew a healthy 42% during the year as more handsets gained music players and users bought and downloaded more music to their phones. With that market growing, sales of simpler ring tones declined.
The mobile gaming market jumped 13% to ¥848 billion, and the e-book market expanded 220 percent to ¥221 billion.
