If you want to be efficient, your language ability must be strong. I heard that there are counterpart schools in China, that is, studying in China for two years before going to Japan for university entrance examination, or enrolling students from counterparts, which is more efficient, but I personally think it is best to have at least enough time to enter a language school, so that you can learn more about Japanese society and then have the opportunity to choose a university.
As for what major to study, I want to tell you that it is useless to study anything. If you study economics, you can engage in economics, and if you study literature, you can become a writer. Maybe it is possible that you still lack Japanese after graduation. I mean, you can't study hard, let alone admit it. According to the current world, it is difficult to get into any major in Japan, and the vast majority of people who get into jobs rely on contacts. If they strive for it by themselves, their personal level must be very high. Some jobs are not divided into departments, just like in China, a bachelor's degree can take them all over the world. Personal ability depends on a little luck. In Japan, it is not as easy as before. In the past, the Japanese begged you to work and there was a shortage of people everywhere. Now you are begging the Japanese to work, and the first one to find a job is the calf with relatives. It's hard to find yourself ~ I'm not alarmist, it's reality. The buddies who work around are all relatives. If you have a visa, it's actually the same. If there is no visa, it will be very troublesome. Now Japan has long passed the gold rush era. Studying in Japan is purely gold-plated, and it is by no means a big money. It doesn't matter if the language is not good, it is a waste. . Since the financial crisis in 2009, the Japanese economy itself has collapsed and could have slowed down. As a result, such a big earthquake struck, which was even worse ~ absolutely devastating to Japan! ! In addition, I suggest you study in Kansai. I'm in a panic in Kanto now ~ Although it seems calm on the surface ... China people have retired a lot from the Immigration Bureau of Shinagawa, so they can't leave home and have to stay in Tokyo. Hey ~ it really feels like the end of the world ~
