There are generally two paths to choose from when applying for a master's degree in Japanese:

1. After studying in a Japanese language school, he was directly admitted to a Japanese university (monk course);

2. Apply for the "postgraduate" course at the National University of Japan, and after half a year to two years of study, enter the university (monk course) of the corresponding tutor at the corresponding university;

If you choose to study in Japan for your senior year, you can apply for admission to a language school in April or July of the year you graduate from college. To enter specialized courses in Japan, the Japanese language requirement is Japanese level 1 ability and level; Whether you can enter a university depends on your professional skills. As long as you pass the make-up exam, you can successfully get your diploma and bachelor's degree certificate without affecting your application.

Now, the most difficult thing for you to solve as soon as possible is the visa issue:

1. Confirm the reasons for refusing the visa (reasons for non-delivery and interview results of the school you applied for and the Admissions Office);

2. Keep all the materials of the last application;

If you can't solve and provide the above two problems, it is basically impossible to apply again; I suggest you solve these two problems before considering others.
