From my understanding, all cultures are blind to themselves and it is only when we get out and experience the open world we start to see how narrow we are. the Japanese also tend to be quite orderly and structured based on drilled cultural rules and I think you guys have a rule for everything and every aspect of life. This would make the common sense only common in that environment, perhaps. I think all cultures have similar in some ways.
It is very cool that these days we are not locked in to our experience like the past, even if we are only able to explore digitally.
Thanks for taking the time.
