I run a Japan related website that has fairly high traffic from English speakers in Japan. Indeed, G Japan ranking algorithm is still old, though, not as old as Feb 24 update. It seems that the English language searches there are quite different in Google Japan when searched from the United States. What is interesting is that the index is as new as the one in the US. I wonder if Google.com is used as a testing ground and once they are happy with it they propagate it worldwide.
