Why do Japanese people have the greatest work pressure?

This is mainly due to the Japanese's strong sense of survival crisis. Japan is an island country with many volcanoes. As early as the 1980s, Japan made a film called "The Sinking of Japan", which was about the full-scale eruption of a volcano, which was no longer suitable for human habitation, and mainland countries extended a helping hand to help. As we all know, Japan invaded China under the banner of "Glory of Greater East Asia" with the intention of emigrating to the mainland. As a result, with the defeat of Japan, the immigrant's dream was shattered. Whether in the past or in the future, the biggest problem that plagues the Japanese people should be the crisis of survival. Only by making yourself bigger and stronger can you win a place in the mainland on the day when the science fiction of "Japan sinking" becomes a reality!
