I think it at least depends on other factors as well. For example the German city of Düsseldorf is very welcome to Japanese business, and it resulted in a lot of infrastructure like Japanese schools, kindergardens, cultural institutions , Japanese chamber of commerce, restaurants, doctors with Japanese translators, a temple, as well as a huge yearly Japanese festival. In the 90s almost all of the Japanese living in Düsseldorf were managers, i.e. paid well. There is no crime, they cause no trouble, they usually just don’t speak German because they live after a 1-4 year business stint. They are very liked among the local citizens. Meanwhile when Turks try to build a mosque chaos ensues. But the Turkish population is not a bunch of rich nomads.
