I don't think the point was to look ahead at your legacy but to look back and see what we can learn. Japan is interesting in this respect as it is a nation that has a long and generally stable history. I remember reading in the Guardian when the tsunami happened about a coastal town wit a shrine up a hill and a story the townspeople told about going not to the hill over there during the tsunami of 1000 years ago, but to the less obvious vantage point where the shrine was. Turns out this 1000 year old oral record saved a lot of lives, 2 tsunamis a millennium apart and an unchanging landscape.

Although what this tells us about how to run an inn for 1300 years I'm not sure.
