Sitting in a cafe in Shibuya, Tokyo ( at the moment ), I would say there's a "oneness" to everything they do. Inconveniencing others is the height of moral crimes you can do here ( see your family being fined for your suicide [1] ). I think this permeates their culture to the point where they're more efficient so that they do not affect others, i.e. how on time trains are in Japan [2]. Of course, this is speculative, but it certainly does not feel like a, "I'll get mine, before you get yours culture" here.
I ran into a term some years ago, giri. Seems to be a remnant from their feudal times.
Something about reciprocal duty or some such, meaning that workers put their honor into their work with the expectation that they get looked after by the boss/lord in return.
This also seems to be the background for a lot of "drama" in their entertainment, where a character will struggle between upholding giri and their emotions regarding the task.
