Why do Japanese people use too many English words?

Actually, a lot of western sounding names came from Spanish or Portuguese. Like a bread, it's a "Pan" in Japanese. Japanese don't call it, "Bredo". Western culture came from Europe to Japan, so they naturally copied the name from it, not from English word. They are not imitating English word. Perhaps, if they do, so what? You should study more about other people's culture before you make silly offensive comment about that.
