What major do Japanese companies in Shanghai generally need to recruit (except Japanese, of course)

Just worked in Shanghai for a year and a half. Personally, I think we should learn Japanese well first. If I can communicate well in Japanese, will other skills be less important? Being young is also an advantage, which means I can't learn a lot. Because when it comes to employment, companies also know that you have just graduated, especially large enterprises, and they will conduct training. I graduated from foreign trade Japanese, but I still work as a translator in the company. Later, it was slowly handed over to me for documentation and customs clearance. Later, I switched to be a business assistant. I think if I speak Japanese well, I can definitely do business. Also, Japanese people like to drag English. If you must learn English well, they will look at you with new eyes. It's also good to learn accounting from other majors. You can have a try if you like.
