If you want to go to Japan for undergraduate study, you can choose to apply to a Japanese language school first, and then take an international student exam and an on-campus exam in Japan to enter a Japanese university.
Or if your English is very good, you can also consider applying for sgu/g30 project to teach in English, but this method requires a higher level of English, and you need to submit TOEFL/IELTS scores and standardized scores.
The specific situation of each student is different. If necessary, I can make a detailed study plan for you according to your specific situation.
