Baidu.com, China’s leading search company, said Monday it will enter the Japanese market next year. According to Reuters, the company did a six-month study into Japanese-language search technology and believe that between the similarities in Chinese and Japanese and high internet use in Japan, it can succeed. Analysts aren’t so sure the stock went up anyway. Goldman Sachs analyst Anthony Noto says expanding abroad when the Chinese market is still nascent could cause problems for Baidu in China. Then there’s the pesky little issue of Yahoo and Google already owning 90 percent of the market.
