Japan (Tokyo, at least), is crazy fast.
I remember staying at the Shinagawa Prince, three years in a row, and it overlooks that big-ass office park, on the other side of the station.
One year, I look out, and there’s a huge empty lot.
The next year, there’s a steel frame, for several buildings.
The next year, the lights are on, and the buildings are obviously occupied.
Also, their standards are very high. They weather massive earthquakes, quite well.
