One thing I really loved about Japan was how it's so densely populated and how the train system is so extensive and goes right amidst huge apartment complexes filled with people's lives. It's like no other country I know of. 

You get on a train in Japan, and you go right by apartment buildings, face to face with them, many buildings, all different, close together, far apart, some modest, some huge. Buildings sub-divided into boxes, grids, all of them lives that I know nothing about, but imagine. 

Who comes home to that box? What do they do when they get there? Do they watch TV, do they cook, do they do laundry, do they crack open a beer? Do they have a family, are they happy? What is their job, what is their passion, who are they in love with, who are they fucking, are they lonely? 

Lonely in this Borg-like mesh of lives. The person in this box over here might have so much in common with the person in that box over there, but they'd never know it. So many people, so many lives, I love that country.
