Japan's FTC has given approval to Yahoo!-Google Japan search-engine alliance that allow Yahoo! Japan to use Google search results. Reuters reports that "Japan's FTC has promised to monitor the alliance for possible violations of the country's anti-monopoly laws."
Yahoo Japan, in July said that it would adopt Google's search engine, giving the two firms control of almost all of the domestic search market. The move had triggered criticism from rivals Microsoft and domestic online retailer Rakuten Inc, citing the risk of unfair competition.
It said at the time that it had concluded after a thorough investigation that Microsoft's search technology was not strong enough for its needs, citing Japanese language search capabilities as one example.
Depending on what measurement stats you look at, the deal means Google and Yahoo Japan now control somewhere in the neighborhood of 95% to 98% of the search market in Japan.
