In Japan, there is a way of thinking called “shakai-jin”, or a member of society. Since it is not common in the rest of the world, it is very difficult to tell foreign people what it is like.
I always try to explain it in comparison with “gakusei”, or a student. A “gakusei” is on the way to growing up, goes to school, and has a school fee paid by its parent. A “shakai-jin”, in contrast, is a grown-up, engaged in work, and economically independent. However, explanations like this can hardly make sense to them.
This is because, in foreign countries, most students study with a fee paid by themselves, and there are also a lot of elderly people going to school while working. The importance of distinguish between “gakusei” and “shakai-jin” can only be understood in a society where most people graduate from school in March, and in April, they begin to work at companies all together like in Japan.
Nevertheless, in Japan, It is taken for granted that a “gakusei” becomes a “shakai-jin” after graduating from school. Japanese companies often hold “shinnyu-shain-kenshu”, or a new-employee training, and they teach how a shakai-jin should be to new recruits who were a gakusei until yesterday.
