Facebook Audience Triples in Japan During Past Year, According to Comscore

Mixi.jp Substantially Outpaces its Peers with More than 12 Million Visitors in June

TOKYO, JAPAN, August 7, 2008 – Comscore, Inc. (NASDAQ: SCOR), a leader in measuring the digital world, today released a study of online social networking in Japan based on data from the Comscore World Metrix service. The report found that Facebook visitation more than tripled during the past year, while Mixi.jp was the most visited social networking destination in Japan with 12.7 million visitors.

“The competition between social networks in Japan is beginning to heat up with the recent introduction of the Japanese language version of Facebook,” said Maru Sato, managing director of Comscore Japan. “The popular social networking site’s launch of Spanish, French and German language sites earlier this year resulted in strong traffic growth in these markets. If this is a reliable indication, we can expect to see Facebook’s growth in Japan follow a similar trend.”
