The most attractive thing about technical interns is that they can study in Japan without having to bear expensive expenses, and they can also get some remuneration during their technical internships. However, the remuneration of skilled interns is very low, which can hardly support the basic life of interns.
And not only the salary is low, but also the working hours are long. Often forced to work overtime, or even pay in arrears. Before going to Japan, they will go through a long period of training, but during the training and signing, no one will tell them the real life situation of their internship in Japan. So these interns know nothing about the life they may face in Japan.
Moreover, Japanese technical interns seem to study and work, but the system is very imperfect. They can not only use it, but also act as cheap labor and violate their human rights. Although the system of technical interns has been changed again and again, the problem that their rights have been violated has never been solved. Therefore, technical interns are often treated unfairly when studying in Japan, but the intern system cannot guarantee their rights and even personal safety.
These systems also stipulate that interns can't leave internship institutions at will and can't choose institutions to study according to their own wishes. Therefore, even if many institutions violate the relevant regulations and infringe on the rights and interests of interns, these regulations make it impossible for interns to safeguard their own interests normally.
