Did you realize that Yahoo is actually the number one search portal in Japan, followed by Google?
In fact, Yahoo Japan receives over half of all searches and is growing.
Why you ask is that the case?
Some say Yahoo returns better search results than Google in Japan. Others say it is because Yahoo entered the Japanese marketplace earlier than Google. You do a search and decide.
A friend of mine that works at Ogilvy (Jorge Ruiz) just passed me this link to shed a bit more light on why Yahoo is number one in Japan. Take a look. Very interesting. http://www.techcrunch.com/2008/08/23/3-reasons-why-the-internet-in-japan-is-ruled-by-one-single-company-yahoo/
