1. It is basically difficult for graduate students to study law in Japan, because China's domestic law higher education started late and developed slowly, and developed countries such as Japan, Europe and America can't accept the equivalent qualifications of China's law higher education for the time being. Similar marginal international law can be considered. Legally recommended schools are Tokyo University, Kyoto University, hitotsubashi university, Osaka University, Kobe University, Nagoya University and Tohoku University.

2. Japan's business is well-known, and it doesn't need much professional basic knowledge. Many students majoring in Japanese will choose commercial universities. Recommended schools for business include Tokyo University, Kyoto University, hitotsubashi university, Osaka University, Nagoya University, Yokohama National University, Kobe University and Kyushu University.

3. The number of universities included in the system is very small, and most of them are private universities. Tuition fees are high and the quality of education cannot be guaranteed. I suggest you apply for an auditor directly under such conditions, and then find a formal college student as a tutor. Or it is possible to choose a language school that focuses on further studies to transition languages and professional courses, or it is possible to go directly to college.
