But from the school's point of view, if you study in Kyushu University, you may have been admitted by default before graduation. After all, you are one of the biggest empires.

When considering employment, you should also consider that these two universities accept your tutor's accomplishments in this field. If you know the names of tutors, search over the wall for their academic achievements. Good tutors also have a strong reputation.
It is true that graduate students and monks in science and engineering are too busy to work, but it is also true that formal monks in science and engineering can get paid with scientific research funds, and it is also feasible to reduce tuition fees and scholarships. In addition, Japanese professors don't like their students (whether they are formal monks or graduate students who are auditing) to be busy with their work and not trust to follow their own research.
I quite agree with that friend. Don't give up your future potential because of the petty profit of working.
