建前 (I'd even consider it brown-nosing sometimes) is something I think that bugs many foreigners living in Japan, as it does me because it's done so commonplace here. I'm starting to do it (unknowingly, but probably from positive-feedback) just for the amount of gregariousness it brings. I would even go further to say that Japanese language it self is blemished in 建前 because of the culture's apprehension towards conflict and directness.
My mere observation. I had a morning meeting today, and found myself mouth full of 建前.
Obtaining residence: my current visa is (quite long): "Engineer/Specialist in Humanities/ Int'l Services" (技術・人文知識・国際業務) I got this visa sponsored by my first company, which is the most common thing for foreigners. Mine is 5 years, some are just a year long. It all depends on the company and how they file your paperwork.
I don't have permanent residency. I could switch over to spousal visa, but since I still have a lot of time left with my visa, I'm not going to bother the bureaucracy. Also, getting residency isn't as easy; it's like a point system here: how long you've been working, if you went to school in Japan, JLPT (Japanese Language Proficiency Test), etc.
Guarantor is only necessary for renting apartments (from my experience).
Regarding tax, it doesn't change. There aren't any breaks nor special levees for foreigners/people with just a work-visa. You get taxed the same (you can even participate in ふるさと納税 [furusato-nōzei] which is a system where you can decide to pay a certain amount to a different prefecture for tax deductions the following year + a gift from the prefecture that you can pick. The gifts are the best part; you can get high grade Japanese beef, high quality fruits, etc).
