Going to Japan to become a nurse

Hi! I (21M) am currently studying nursing in Portugal (I'm Portuguese). All over the world, nursing has really poor working conditions, but sadly, in Portugal, those conditions are really really bad. So I thought about moving abroad and Japan is a really strong candidate. I know working conditions as a nurse in Japan aren't that good either, but they are surely better than in Portugal. I already know about the National Nursing Exam and the N1 level needed in order to be able to take that exam. I just wanted to see what the people of this sub-reddit have to say about this plan. If working as a nurse is completely impossible, I'd still be happy with taking an English taught masters in Japan. The country just amazes me. My Japanese skills are close to 0 (60 day duolingo streak and that's it). I've also been looking at this sub-reddit since this was asked before, but all those threads were pre-Covid-19, maybe some things changed. Thank you in advance for the answers!

Edit: Thank you everyone for the answers, sadly I believe my dream of being a nurse in Japan will not be possible. Maybe in another life. I guess I'll stick to an English taught masters just for the experience of being there. Cheers!
