There's a distinct cost to that lack of doom. In fact, "lack of doom" depends entirely on where you live in Japan. Most of the country is somewhere on the spectrum of "moving to Tokyo" for economic opportunity. Smaller cities just seem to be a waypoint on that journey.

Japanese work long hours and don't make very much money. The average salary is just under 54k USD. People continue to work well into old age and in many ways Japan's culture and history are becoming lost due to the rural/suburban exodus.
