I wouldn`t complain too much about the housing in America.
The following are examples of the average, typical houses in Japan:
This one is the most typical example I could find quickly. The lot size, and the way the design has no direction is what you see all over the place. You won`t see many garages in average Japanese homes. They park their cars in the little empty space in front of the house. This house has parking for 3 cars


Here`s a typical example of a cheapo modern house. There are really a lot of modern design houses in Japan, but they are mostly cheap, ugly attempts. Modern is very popular in Japan and you see it all over the place, much more than in America.

Of course there are some nice designs (old and modern) in more wealthy neighborhoods, but the above are just examples of the very average, middle income home.
