The president of Mixi Inc. expressed confidence Wednesday the country's most popular social networking Web site will not be beaten by the world's biggest site, MySpace, which has 140 million members worldwide.

"It is difficult for latecomers to enter the market," Kenji Kasahara, who is also the founder of Mixi, said at the Foreign Correspondents' Club of Japan in Tokyo. "Our site is a destination for more than 8 million registered members and they commit to our site by keeping diaries and exchanging opinions in communities on a daily basis."

Kasahara said the more users get together on the site, the more valuable the site becomes, just like auction sites.
