If you want to go to Japan, first of all, you have to pass the language exam. Most universities require Japanese to reach Level 2. If you don't understand the language, you have to go to a language school to go to Japan, but it's not cost-effective for you, because it's not as good as learning the language at home to go to a Japanese language school. I just don't know where you are. I know that there are several schools in Chengdu that can not only carry out language training, but also apply for visas to go abroad, and will not charge agency fees, because they are Japanese training schools: Sichuan University and Southwest Jiaotong University, which have lower fees and lower visa pass rates. The visa pass rate of Japanese schools in Sichuan is very high, but their fees are also very high. You can look up their addresses and telephone numbers online, and you can also call them for advice.
