Yahoo Japan is that country's most popular website. According to NetRatings Japan, the deal will sew up some 90% of all computer search queries in Japan and about half of all mobile searches in that country.
Last summer, Microsoft Corp. and Yahoo Inc. signed a 10-year deal whereby Bing technology would take over search functions across Yahoo sites in the U.S. and many other countries. Yahoo Japan was excluded from that deal because the American company is not a controlling owner.
Yahoo Japan said it also will use Google's online advertising platform. Google should begin delivering search results before year's end, according to the company.
