I think what I can do when I choose to work in Japan has nothing to do with my major. The key is to look at what kind of work you like, what kind of work you are suitable for, and what kind of work you are willing to do. Only by comprehensive consideration can you know what you can do and stick to it.

Although Japanese is spoken in Japan, English, as a common language abroad, can also be enjoyed there. I think you can do the following tasks by yourself, and the key depends on your choice:

If you want to be engaged in the catering industry in Japan, you can go to a restaurant run by Japanese people to do it bit by bit, and the waiter will be the front desk supervisor, then the manager on duty, and then you will be promoted to the store manager. This is also a good choice. The premise is that you can really endure hardships and persist, and it is still tiring to cook.

or if you don't want to engage in such manual labor, you don't want to let your major in college go for nothing. You can also do translation work in Japan. English translation is also very good, with more technical content, which tests your professional skills. But I think this is more difficult, unless your English level has reached the level of perfection, and you are familiar with many words and sentences clearly.

Or you can work as an English teacher and a Chinese teacher in an educational institution in Japan. It's also a very good choice to teach English and Chinese in a bilingual way. It is also meaningful, after all, education is a very great and far-reaching thing, and it is worth working hard as a lifelong career.
