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.
