To put it simply, Yamagata University is not a super difficult institution in the eyes of Japanese high school students. But personally, I think it is not good to draw conclusions about the school's performance. Every school has its own strengths. Yamagata University naturally has strong disciplines, and the people who come out are very strong and awesome. How is LZ's Japanese level? The specific LZ can be checked by yourself. If you don't even have the ability to actively collect information, what about studying abroad? What is found on the domestic internet is only superficial information. If you don't take the initiative to collect it, you will regret it in the future.
Some international students from Yamagata University returned to China for employment after graduation, and some went to other universities for doctoral studies after finishing their master's degree. However, Japan's economy is sluggish and the employment pressure may be relatively high. A few years of studying abroad will become an important life wealth for anyone, and they will not only learn professional knowledge, but also rely mainly on themselves.
For international students, language is the first level and the source of life is the second level. After two passes, you can study with peace of mind. If you spend time at work every day, it may be a problem for people with weak ability to graduate. It is gold that naturally shines, and everything depends on our own efforts.
Yamagata is located in the northeast of Japan, and its economic development is naturally not as good as that of Tokyo and Osaka. But to put it bluntly, the gap between the rich and the poor in Japanese society is not big, and Yamagata also has its own unique flavor.
Finally, good luck to LZ!
