Why do Japanese people live in paper houses and sleep badly?

The traditional wooden two-story residence in Japan has good seismic capacity and is easy to build, rebuild and maintain. When you say paper paste, you should mean Harmony Room and paper door, which is a kind of traditional paper with good thermal insulation and light weight in sliding doors. Sleeping on tatami is only a Japanese tradition. Generally, a harmonious room will be reserved in a house, which is very practical for many purposes such as staying guests or playing for children.
