From the beginning of the 1990s, Japanese mass media and academicians have often reported on the social conditions of foreigners in Germany, especially the Turkish population of Berlin.

Since the 1980s, the Commissioner's office in Berlin continued the research every few years, asking respondents similar questions; the research methodology is solid, based on random sampling from more than 500 respondents.

The more contact that a Turk has with Germans in his/her spare time, the more critical he/she is of German society. Although improvement is very slow, generally, social interaction between Turks and Germans has been gradually improving since the beginning of the 1990s. The German people are becoming accustomed to some Turkish be
