You can apply for permanent residency in Japan after working as a highly skilled professional with 80 points or more for one year. However, I would advise against moving to Japan just for a job, the culture shock is too great. You have to have other motivations, and the job follows.

That’s less than 4750 EUR per month. My last 8-month contract in 2021 was priced by client on 7k EUR. In that case it looks really interesting for everyone having a company in EU and wanting to relocate to Taiwan. Very interesting, thanks …
Yeah, but you can’t do it yourself just because you have some skills, but instead you need to find a company that is able and willing to help you with it. Also what if you just want to create your own company instead or some other form of (in fact) self-employment?
I did choose Romania, because Japan was completely closed when I was creating a company. Instead of conditions you said I was able to create a company fully remotely and relocate to it later when everything was ready and waiting for me. All I need to have was an ID or passport. Unfortunately not every country is so open.
I completely understand you … When Japan government did not want people to enter some public place instead of restrictions against human rights they choose to … close for example a park. That freedom to go outside, peaceful people without any religion war, no NO GO zones, no Fit for 55 and so on … That’s a completely different culture, but you know what? I think that somehow I can deal with such a shock. 
But seriously … It would not take long for me to decide if I would choose (in short) honne and tatemae over all above. The bigger shock for me is how EU and US changed over all those years.
There are options. Not for self-employment, but for example the city where I live provides a startup visa. You need to have a business plan however… So yes, it’s a complex process with strings attached. But that’s Japan 
Looks better and I would definitely bookmark it 
, but still if they would not truly open then they would miss more and more money. The business is not about conditions, visa and other paper work stuff, but simply people have some ideas, some of them may fail even if everything was properly prepared. When investing money in some company people don’t want to hear “maybe”, but they want to simply estimate costs and time they need to invest especially if it’s about startups. Any conditions only favors corporations which have people for doing paper work and lots of money.
The country derives income from taxes, so it should do everything to help doing so. There should be one simple business/working visa for everyone for let’s say a month, so everyone can enter country to for example create a company. The person with such visa should be guided on airport where tax office can be found and there should be guided what to do in specific case. When everything is set additionally they should promote free language courses, exams and other stuff from which they would derive something from.
Unfortunately politics in many countries does not understand that. One may say that they are going to improve, but would you accept same when it comes for example for package delivery? Maybe the package come to you after a year, but before changes it took 2 years or more … Who cares? In business in general any kind of delay (delivery, paper work etc.) does not affects positively on market. I wrote above to show that’s one of the reasons of problems on job market.
btw. @adamu would you mind if I would ask you on pm about help/questions with what you have linked? For now things works for me in Romania, but maybe later I may be interested in this topic from from practical side.
This made me think about why remote.com is doing facilitating the legal paperwork to provide the opportunity for people and companies to work together regardless the location they are based.
Most of the information I know is already in the links above. I just wanted to respond to your points about Japan demonstrating that the options are there for people that are interested.
