Wool is more effective insulation than cotton, and also insulates when damp/wet, unlike cotton (thus the saying "cotton kills"). I suspect the reputation of this type of jacket is more cultural than anything.

Not a factor when (again) not exposed to the elements.

It really is not. I suggested it from experience because I have one in my closet.
Isn't that just a regular jacket, in Japanese style?
Not really. In terms of length it sits somewhere between jacket and coat, but is also very much designed to be worn indoor (as traditionally japan doesn't use central heating). It doesn't much protect against the elements as it has a non-overlapping lapel with cords stiched on the edge for closure. In essence the front is mostly open, even when tied.
They're thick padded cotton, and once the vest has warmed up (which doesn't take too much time) it's really warm and comfy, if a tad bulky.
