Japan is the only country in the world where men are less happy than women… Surprising data shows that the more male-dominated a country is, the more unhappy men are

Here's a summary translation of the main points-

Is the happiness level of Japanese people high or low compared to the rest of the world? Statistical data analyst Yutaka Motokawa says, "The global standard is that women, the elderly, and those with low education tend to have a lower sense of happiness, but the Japanese are a unique people who go against all of this."

As can be inferred from the fact that depression is more prevalent in women than in men around the world, the gender ratio of negative emotionality (men ÷ women) is below 1 in all target countries except Japan. In other words, women are more likely to fall into negative emotions.

Gender theorists tend to jump to the conclusion that this global trend is caused by gender discrimination. However, as can be seen from the fact that suicide is generally more prevalent in men than in depression, things are not that simple.

For example, Nordic countries generally have a high awareness of gender equality, but even within the same Nordic countries, in Norway and Denmark, women have significantly higher levels of negative emotions, while in Finland and Iceland, the male-to-female ratio is closer to 1, showing considerable differences in the situation.

The most notable thing is that Japanese men are the only ones whose negative emotions exceed those of women (by 14%). This phenomenon is in line with the notable female dominance in happiness among Japanese people in World Values ​​Surveys and other surveys.

The reason for this could be either that women are more respected personally and socially than men, and so are less likely to experience negative emotions, or that there are special social environments in which only men are more likely to experience negative emotions. I believe that the latter aspect is more prominent.

In Japan, while institutional equality between men and women in terms of inheritance and voting rights was realized after the war, in modern times women have been largely liberated from the old Confucian morality, whereas men are still bound by old moral values ​​such as the idea that men must be the breadwinners of the family or protect weaker women. I think this is the result of this. Men are less likely to feel happy because of the high expectations placed on them.
