Japan is a highly industrialized, developed nation where essentially every square inch of land that is not mountainous is fully developed. If your cup of tea is poorly designed housing units and factories, you'll love the view.
Several things did catch my attention though. One is the continued politeness of the Japanese. The train conductors bow each time they enter or exit a car and are highly respectful, as is everyone here. The other thing that was ideal is that no-one, repeat no-one speaks into their cell phones on the train. There are only small areas of the train where cell phone use is allowed and it makes for a very pleasant ride.
