Yahoo Japan and BrightTag have expanded upon their strategic partnership , making Yahoo Japan the exclusive Japan market distributor of the BrightTag One platform.

BrightTag says that through the partnership, Yahoo Japan’s dominant market position and its own patent-pending Server-Direct technology will create “a new standard for data collection and distribution across the entire Japan online media market.” That market, according to projections from eMarketer.com/comScoreDataMine.com, is expected to grow to $8.91 billion (¥835 billion) this year, making the country the second largest online media market in the world (behind the US and ahead of the UK, Germany, and China).

“Managing tag code and the data associated with tags has become dramatically more complex for ourselves and our clients in recent years,” said Masatsugu Shidachi, Corporate Officer, Head of Marketing Solutions Company, Yahoo! JAPAN. “BrightTag’s versatile technology solves a wide range of integration challenges for both Yahoo! JAPAN and our clients, helping to position us for faster growth and more rapid innovation.”

“The BrightTag ONE platform is more than just a tag management system,” Shidachi added. “It leverages data instantly and effectively through the cloud and provides all parties with a unified data integration layer making the linkage easy and seamless between website owners, publishers, and the growing number of digital marketing services available in the Japan market.”

Yahoo Japan will offer its new Tag Manager, powered by BrightTag, to its direct, agency and medium-sized business clients.

Earlier this week, Yahoo Japan entered into a joint venture with Free to invest in social gaming.
