TOKYO (AP) - Japan will start an aggressive push to market abroad its mobile technology, especially the nation's popular "wallet phone", a government official said yesterday.

Although Japan boasts some of the most sophisticated cell phones in the world, delivering high-speed Internet connections, digital TV broadcasts and video downloads, the nation has failed to make its handsets, wireless technology and mobile services hits outside of Japan.

The latest initiative spearheaded by the government with an industry group of Japanese carriers and manufacturers is an effort to help Japan catch up in wooing global users, said Masayuki Ito, official at the Ministry of Internal Affairs and Communications.

Among the wireless innovations Japan hopes to peddle is the wallet phone. The technology relies on a tiny computer chip called FeliCa, embedded in each cell phone, which communicates with a reader-device at stores, train stations and vending machines for cashless payments.

FeliCa was developed by Japanese electronics and entertainment company Sony Corp. Such technology is more common in smart cards, popular in Singapore and parts of Europe. But Japan hopes to market the technology abroad for cell phones.

In Japan, wallet phones have been available since 2004, introduced by top mobile carrier NTT DoCoMo. Most recent handset models here have the wallet function.

Older Japanese technology had compatibility problems with other global standards, but new third-generation technology allows new products to be used outside the country, and can be more easily adapted to overseas products.

Japan leads the rest of the world in 3G cell phone proliferation, with nearly 104 million 3G handsets in use, or about 90 percent of cell phones being used in Japan.

Japan also hopes to promote overseas other kinds of wireless technology, including 3G mobile phones with GSM, or Global System for Mobile communications, which allows the same phone to be used in most countries.
