Almost isn’t good enough. Our current economic system also demands growth and not stagnation. Immigration is still better which is one reason many European governments changed their stances on it.
Sweden has about ~5 physicians per 1000 people, largest migration groups to Sweden, Syrians has a rate about ~1.3, Iraqis ~0.7, Indians 0.9, Pakistani 1.1, Somalis ~0.02.
And then you have other important public skilled professions like teachers & educators, law enforcement, health services etc.
Thus low skilled immigration increases shortages on high skilled professions.
Why can't we just give people the freedom to do whatever they want, society will sort itself out and everything may balance out in the natural order of things. One point is that unites both, right and left, is to make life a living hell to those who dont give importance to these petty issues and just wanna work together with others to make this globe a better living place for all...
You still also need low skilled immigrants. Otherwise, you’re not going to have people do terrible jobs like mortician and meat packer positions to name just a few jobs that native Japanese are hesitant to do. Just to remind everyone, AI and robotics are still not there yet. Anti-immigration advocates, just like the brexiteers, fail to account for reality.
Thus you agree with me that integration is huge cost, because immigration will create big friction within the Japanese society and that is a cost.
It is interesting that you admit that Japanese society is anti-immigration and yet you push this as solution to their problem. That is elitism.

Another alternative is to increase salaries, but immigration does the opposite, pushes wages down, especially for low income jobs.
Problem is that low income jobs is net loss in payed taxes in high tax welfare states, because the tax they put in is lower that the benefits they get, thus the more low skilled immigrants you bring the higher the taxation must be, but too high taxes will have a negative effect on general employment and business.
Believing that low skilled jobs is something beneficial for an advanced society is like believing that handing out shovels to dig holes is net beneficial in world with excavators.
What a society becomes rich on is processing either goods or services to something of higher value and preferably in multiple steps, not flipping burgers at minimum wage.
