1. Japanese universities, including the best universities such as Dongda University, Tokyo Polytechnic University or Tokyo Nine University, do not have a mandatory GPA, but only require the submission of transcripts for reference. But according to my personal observation, the requirements for undergraduate grades are not very strict. On the contrary, a college background is more helpful to enhance your impression. As long as you can graduate smoothly, your situation should be favorable. Of course, the premise is that you have shown a good professional standard in the college entrance examination and the papers/research plans submitted.

2. The problem of money. A deposit of 200,000 RMB is necessary, but you can borrow this temporarily. It only needs to be frozen in the bank for half a year, and it doesn't cost money. You can also find other ways to prove your income. Universities should try their best to choose public schools (the better schools are mainly public schools), so that more than 80% people may get half of their tuition fees and more than half of them may get scholarships. At the same time, if Japanese is good enough, you can work. The combined income of part-time jobs and scholarships is basically enough to support study and life, and there won't be too many places that need family subsidies.

About the preparation now, besides the economic preparation, it is mainly the improvement of language and specialty. Language should not only pass the first level, but also be familiar with the vocabulary related to your major; In terms of professional ability, we can start collecting some Japanese academic papers to see the trend of Japanese academic circles, and also provide reference for choosing universities and tutors. Other specific documents can be prepared according to the requirements of the intermediary (if looking for an intermediary) or universities and embassies.

4. You can start to contact the tutors of Japanese universities after your senior year. Generally, the email address of the professor is published on the university website, starting with sending a greeting email. Pay attention to practicing the norms of email writing.

Attachment: Yokohama National University is the best in further study upstairs, and the university is only the capital. It's best not to advertise.
