As a Japanese international student, is it okay for parents to seek a Japanese tutor as a guarantor when traveling to visit relatives?

Even if your mother has no job, as long as there is a bank guarantee certificate, there is no need for a guarantor. The most taboo thing among Japanese people is the fear of giving money to others. Your mentor only has a master-disciple relationship with you, and he does not know your mother. It is too bad to make this request to him abruptly. If you really want to find a guarantor, it is best to find one among the Chinese.
