We can chalk this up to the fact that the Showa era was one long economic boom besides the disastrous 12 year war that ruined japan, but the people who survived the war saw the economy explode even larger and were retired with lots of money long before the economy crashed in the 1990s which adversely impacted the japanese 'baby boomer' equivalent generation (the later showa), who are now in their 60s (Toriyama, Murata, TARAKO) and are likely to have worse health outcomes from greater stress levels from working harder than their parents for less reward knowing everything can be taken.
Japanese 'gen xers 'millennials' 'zoomers' 'gen alpha' (heisei and reiwa generations) will obviously live even worse and shorter lives than their long-lived great-grandparents and grandparents and their shorter lived parents.
This can all be chalked up to economic factors- a worsening society and economy leads to poorer health outcomes as wealth is siphoned to your 119 year old great-grandpa and keeping him alive as a national symbol of prosperity, instead of spending resources on you- the young person who would actually be economically useful if only they allowed you to develop skills and use them to grow the economy. (this is the same reason why the US spent 1 trillion dollars for 500 billion in GDP growth, because money spent on shoring up the businesses and pensions of elderly people does not benefit the economy, amusingly the government of elderly people does not understand why in the 1980s giving money to themselves caused the economy to grow when they were young is not causing the economy to grow now that they are old- SAD, DELUSIONAL!).
