Story for 'Villa of Kamiya Denbei':
Until the middle of 20 century, Inage area was a long beautiful beach, and the place had prospered as resort of Tokyo's suburb. Denbei Kamiya's villa was built in 1918 -around 90 years ago- as concrete building of modern western style, it's still located at the place now. Residents and visitors of the villa had been enjoying to see the sea in that age. In 1960's, the beach and sea were reclaimed, and became new land which is called Mihama area now. At present new seashore that has been created as artificial beach, is located at 2km distance from Inage area.

It's possible to regard 'right' as having same degree of certainties in the both paragraphs.
It might be possible for us to certainly predict a state of world as 1 second future. As same as the degree of future prediction, it might be possible for us to certainly know a past state of world of 1 second ago. A certainty of past history is same as degree of future prediction. In a way, past has an uncertainty as same degree of future.
Time has no history as certainty.
In order to understand this world much better, we have to dispose of a concept of 'history' which has been supported by 'certainty.' It increases uncertainty that a distance of time either past or future is far. Things that are kept observations on can only obtain certainties within the term of observation.
