Meaning of Mindo(民度)
It means the level of social manners.
Since Japanese Minister used this word, some media translated this word.
Other translations are “cultural standard”, “the superiority of its people”, “national chauvinism”
Most of time if people use this word, they feel superiority.
So “the superiority of its people” is also correct, I feel.
The worst is “national chauvinism”, it makes a really bad and wrong impression!!
Many Japanese are not good at English, it means if some media want to create bad image of Japan in English, they can do it easily!!
A: You moved to high class residential area, how do you like it?
