One of the things I was most excited about when I got to Japan was their railway service. I'm not a huge fan of driving in the U.S., and the idea of getting to and from school without driving was really exciting to me. Ever snce I arrived, I've been using trains almost daily to get where I need to go.
There are a few ways people get around Japan. Walking and trains tie for first place. I've been walking every day and taking the train most days. Bikes come second. It is very common to see people biking around Japan. In urban areas, most people bike on the roads because the sidewalks are too crowded. In the suburbs there are no sidewalks, so pedestrians and bikers share the space. Cars come in third. They are a must in remote rural towns, and they're a luxury in the suburbs. People use cars for personal transport when they don't want to use a train. Most of the cars in cities are taxis and Ubers. I'm not sure where buses fall on this list. I've only used them once, when I visited my family's grave, but since major train stations like Shibuya have bus stops right outside, there must be people who use them relatively frequently.
