Good english except japanese

Hi

Hello!

Today It is summer in japan.

Generally, Japanese cannot speak and write English well. But Other coutry people use English very well.

I realized.

We study and work hard. It is famous things.

But, we are kindergartener's level. Why?

Is the educationaly wrong?

Japanese like "an examination".

So I guess we only study english for an examination. For example, university.

But there is an examination in other countrys.

not understand.
