According to statistics, most people in big cities in Japan also live in apartment buildings. Only in small cities, suburbs of big cities and rural areas do people live in self-built small houses! So at least 40% of Japanese also live in apartment buildings. Not everyone lives in a single house!
In fact, Japan gives us the impression of living in a single-family house, mainly because of Japanese dramas and cartoons. This is because of the development of Japanese film and television industry, but actually not many Japanese can live in single-family houses.
More than 80 million people in Japan gathered in the Kanto city circle. 80% people live in high-rise apartments. Only a few rich people live in villas and small single-family houses. There are not so many small single-family houses in Japanese cities. In fact, small single-family houses are not located in rural areas of Japan. It is city people who long for small single-family living space, which is the characteristic of small single-family residential environment in movies, TV dramas and cartoons. We happened to see this and mistakenly thought that a certain family was very popular in Japan, which led to hallucinations.
There are more and more families in small and medium-sized cities in Japan, which is related to its highly developed social economy. They will try their best to build their own living quarters, even small houses in small corners. At that time, advanced building technology played a role, because the homestead was very small, so high-rise buildings were built, which is why small single-family houses in Japan were two stories or higher.
