How long does it take to learn Japanese? Can you be a translator or work in a Japanese company?

I am a Japanese major. Generally, we take N 1 two years. Generally, I want to be a translator. If it is a life translation, N 1 is no problem. If it is a strong field, it is still far from it. There are many technical terms that you have never seen! After all, it's a language. Don't think about doing translation from the beginning. . . As students majoring in Japanese, we spent two years learning N 1, but N 1 is still in the superficial stage of Japanese, and it is still early to learn the essence of the language. Also, some Japanese animators have Kansai accents, while Japanese people have foreign accents. Many animation languages are exaggerated and impolite, and they will be laughed at if they are used in life.
