Admittedly, compared with those universities that can be admitted normally, there are few universities with merger system, but most public universities in China have merger system. Tokyo University, Kyoto University, Osaka University, Kobe University and so on must have been institutionalized. It is not surprising that there are few private universities, and some of them still have settings. Therefore, the landlord should not think that the better the university, the less it will be included in the system. This is a wrong idea, but the number of schools and students enrolled in this system is obviously less than the average.

As for the specific requirements, it really depends on the specific majors of specific schools. I just checked the literature department of Kobe University, and there is no special requirement for English, so I don't need to submit TOEFL scores when I apply for the exam, just saying that international students should have an average score of above. It is estimated to be more than 250 points. The rest have no special requirements. Then every particular school will hold an entrance exam, and you must pass that exam. In fact, the standards for applying for universities are quite low, and most people can apply. The main thing is that you should do well in the examination questions from other schools. The more people apply for the exam, the fewer students will be admitted, and they may be brushed off. This is why many people say it is difficult to make up. Moreover, many universities will ask to see if your major is right. Even if there is no special requirement for your major in the enrollment conditions, you will take a lot of professional content, so it may be more difficult if it is not that major.

As for whether there is any special selection for international students, I just entered the Department of Literature of Kobe University, and it is really an examination specially set for international students. Moreover, the number of students enrolled each year is open, and most universities have it online. Find it yourself. What's more, the Japanese level of international students is not the same as that of Japanese students. Admissions schools will examine the Japanese level of international students, so I think most of them should have exams specifically for international students.

I am nervous about completing the credits for the first two years in the next two years, so I can't answer you professionally. I haven't experienced it myself, and there are few books compiled around me, so I don't know the specific situation.
