Like most people in the west, Japanese tend to live in apartments or houses. I visited a house exposition center to find out what a Japanese house is like and thankfully was allowed to film in one house.
House exhibition centers like this seem to be quite common in Japan. They do not exist for single apartments, but there are mansion show rooms for that. These showcase apartments of soon-to-be finished skyscraper buildings.
The size of the house in this video is 202.09 square meters in total, with 113.09 sqm on the first floor and 89 sqm on the second.
