As a veteran resident approaching his 28th year in Japan, I would like to offer some simple advice to tourists, newbies and fellow graybeards as well. Which is:
Do not die here. I'll wager you will not enjoy it.
This is not a comment about final destinations, or even about the port of embarkation. For I suspect in the larger picture of life, Tokyo or Osaka are just as fine for dying as Tahiti, Palm Springs or Maui. At that point, one is supposed to savor the moment and not the locale.
