I found out how to fix it, seach somthing in google the school down to the botton there will be a use location button at the botton clicking will bring up a pop up menu asking to use your loaction allowing it will then fix the problem making google to go to the right one.

This looks like it work i will comment more if this still happend.
 
I'm still having the issue I also have a bootcamp verson of windows 7 on it to with this same problem happaning. I' ve been looking around could this problem be a google redirect virus?
 
Also getting the same problem on youtube and the ios youtube app where i'm getting Japanese ads.
 
Update: even tho Gooogle is niw going back to .com insted of .co.jp all ads on google is japanes ones (just like in youtube) this happens in all browrses pc, mac, ipad and iphones...

One this is fix but I dont know how to fix the ads but might not even be a problem.
