I lived in Yokohama for one summer, working odd jobs at a small firm. I stayed in the eastern part of the city, in my first real apartment. I had a tatami mat for a bed, and a classic Japanese ofuri bathtub.
When I wasn't working, I used an old, two-gear BMX bike to explore the city. It was tough to ride on inclines, but the heavy metal body picked up a lot of speed going downhill.
I don't know if Yokohama is a typical Japanese city. Less than 20 miles from Tokyo, there were certain things there I hadn't seen elsewhere: unexpected but beautiful fields lapping up against the city limits, pornography on TV every night at 10:00, dilapidated stores crowding against my apartment.
I liked the city. I was seventeen and trying to sort out my feelings after an aborted relationship. When thinking became too much, I'd take the bike out and look around, usually late at night.
I started smoking regularly and picked up insomnia that summer. But mostly I remember the rush of speeding down darkened streets, and realizing that the best part came from being alone.
