Japan is a society based on the guarantor system.
However, a guarantor is still required in various situations in the social life in Japan so that one can say that Japan is a society based on the guarantor system. When you rent an apartment and apply for an entrance examination for a university or a special training school, and when you are admitted to a university, you need a guarantor. Even after you enter the school, when applying for scholarship or tuition reduction, one will need a guarantor as well. Japanese students are also required to follow this system and they usually rely on their parents or relatives are usually responsible for them. But foreign students are required to find guarantors living in Japan, so it is not easy to find them after coming to Japan.
