I worked for a Japanese company, for a long time, and the Japanese were really big on personal relationships.
They weren't necessarily "warm and fuzzy" ones, but they were based on mutual respect and shared interests. I worked with many folks for decades, and we got to know each other well. We didn't always like each other, but we respected and supported each other.
Personal Integrity isn't something that can be faked. If you are in the kind of relationship I just described, fake integrity will be exposed fairly soon.
