wrong message googling my site name

My site name is Tokyohomeopathy.jp If I google tokyo and homeopathy, I get the wrong message on the third page of the google search. How do I change the message?

This happened because a friend copied my English site for the Japanese site installation. So the English message comes up automatically. I need to translate that message into Japanese. I need to change the message that was created on installation.

Thanks,
Ellen
