There are very few differences between German and English, but there are tons of difference between European languages and Asian ones.
I studied in Korea, I was specially interested in Hangul, and found Japanese extremely similar to Korean in the cultural side of things.
For example, there is a iconic concept in the US of "bad guy", "rebel against the world". It simply does not exist in Korea, or in Japan by the way. You can't talk about "bad guys"to them, because it does not exist in their world.
The same happens with different levels of respect and politeness in Japan, it does not match anything the Western world has.
Words are like icons or shortcuts for something the culture has.
The intimate relationships, the families, the social contracts,violence, the way of working... it is simply another world of thinking.
