Browser share of Google Chrome in Japan

Google Chrome put a significant impact on the browser market right after it has launched a week ago.
It is said that it took more than 1 percent of the share in the browser market immediately.
However, as I check the traffic of my "most non-technical" web site, it's share is still 0.5% and it does not change AT ALL for these 5 days.
We can see google chrome on the TOP page of the Google Japan, but it seems like most of the people are just "watching" the new browser.
In Japan, IE is still too strong. It's share is almost 90%, and Yahoo! is still taking advantage of the Google in the sense of the web traffics.
I guess it will take some more years for Google to take advantage of the browser shares in Japan.
