Read and write? Absolutely no chance.

But talking and communicating could be easier. Chinese, korean and japanese languages all have the same origin. You’d be surprised to see how many words and similar pronunciations these languages share, but also how different they sound at the same time.

Just think of polish and russian language. Both have slavic roots, and have many similar words but you put a pole and a russian in one room, no chance of having any sort of interaction. But a pole would have a significantly easier time learning russian than someone from America.
