Ups and downs

2015-07-27 | からnakmas | ファイル: 未分類.
In Japan, there are some big cities,
which are geologically with many ups and downs, not plain.
Their populations actually are over 1 million.
If with many ups and downs, …
people’s transfering gets quite hard,
roads and lands for each house gets narrow unintentionally,
in cases, as narrow as cars cannot go through.

Why people are willing to live in ups-and-downs lands,
and build big cities in such places?
