How long does it take to learn Japanese before you can work as a translator or work in a Japanese company?

I am a student majoring in Japanese. We usually take the N1 exam after two years of study. Generally, if you want to be a translator, if it is daily life translation, N1 is not a problem. If you are more specialized in the field, it is still not good. It's far away, and there are many professional terms that you have never seen before! After all, it is language, so don’t think about being a translator from the beginning. . . Our Japanese major is very intensive, and we only need N1 in 2 years. However, N1 is still in the superficial stage of Japanese, and it is still early to learn the essence of the language. Also, some of the Japanese you learn from watching anime has a Kansai accent, which means Japanese people have a foreign accent, and many of the languages ????in anime are exaggerated and impolite. If you apply them to life, you will be laughed at
