Law and medicine are the most difficult majors in Japan, but it is easier to take an examination of a specialist, and you are a Chinese medicine practitioner, which is easier than western medicine. However, this major seems to be a major that burns money. It is said that the tuition fees of countries and institutions are also very high (if they are graduate students, it seems much lower). However, it is still difficult to find a job after graduation in Japan's economy. But by the time you graduate, it will be three years later. Maybe the economy will be better then. When you come to Japan, you have to study and work harder than at home. Good luck! !
