Why the Japanese poor English?

Why the Japanese poor English?

Spanish Father replied. He is my friend
"Because there is no need to use. Europeans can speak several languages​​. Because it is necessary. However, in Japan, need not foreign language."

Most industrial products are made in Japan. Self-sufficiency of food is also not impossible. Foreign famous book has been translated into almost all Japanese.
We Japanese do not feel the lack. And, I heard that Americans also speak a foreign language is not good.

I want to create a new certification.
"Rate of using foreign language is inversely satisfaction of the country."

I learned English at school for 8 years. I can read English. But, I can not write my own opinions. So I began to write this blog. If there are any mistakes, please comment me.
