[contingencies]

All I will say to that is that, as programmers, we should learn to distinguish between historically attributable derivation (evidenced fact) and vague conceptual notions such as culture and even more derivative, fuzzy and subjective notions of the potential equality of instance thereof (opine). This is why I spoke in generalities and placed "Japanese culture" in quotes, because it is a vague and popular term without a meaningful and precise definition.
