physical laborer in Japan
It can be seen that 90% of the foreign students are privately-financed overseas student. It means 90% have no scholarship, they have to go out to do physical labor.
In the background, Japan is currently experiencing a declining birthrate and a rapidly aging population. Simply speaking, there is no people to work.
So here the government had an evil way to get the laborer, making Asia young people come to Japan under the name of overseas education.
After the students come, most of the 90% are engaged the hardest physical labor, and women students are even engaged in prostitution.
I want to tell the person who wants to come to this evil place, After you got the well-night worthless diploma, your health of body and mind were exhausted, and yourself were down and out.
