> importing people who have no better options

This is literally how America grew.

Mind, you want to actually integrate people instead of running some godawful Gastarbeiter program.

Except Japan is already "grown."

That aside, It's better to let the _overpopulation_ problem in Japan solve itself by letting birthrates fall than to continue the issue by importing more people. It's not normal to have cities with population densites of 6,158 persons per square kilometer. Yes, there will be an economic price, but it will be short lived (30 years) rather than something that will continue forever.

"It's not normal to have cities with population densites of 6,158 persons per square kilometer"

It's pretty normal for those who live in such places, and not really significantly more "unnatural" compared to sorts of social arrangements we evolved with over 100s of 1000s of years than, say, suburban style living where each nuclear family is significantly isolated from the next and there's no practical way of getting around other than by motorised vehicles.

I wonder what total % of the human population these days do live at densities over 5k/sq. km. - would be a non-negligible amount at least (China has a number of cities with significant metro areas that qualify), and if you lower the bar to 3k/sq. km, it'd quite possibly be a significant fraction, maybe even more than 10% of all humans? The only actual stat I could find is that "apartments accounted for 36.3% of all households globally in 2013".

Oh and Japan's population density overall is a bit over 300 per sq. km., so there's plenty of opportunities for those choosing to live in much denser parts of major cities to avoid it if they wanted to.

So you don't think overpopulation has anything to do with falling birth rates? Do you think Japan will just continue to have low birth rates forever?

It's possibly a contributing factor, but Japanese families are quite accustomed to the idea that their kids will grow up in what many of us in less-densely populated Western countries would consider uncomfortably small spaces. I'm not going to make any predictions about "forever", but unless they start ramping up immigration and allowing in those from cultures where having larger families is more of a priority, I doubt it's going up any time soon.

There are people who live in "apartments" in Tokyo smaller than the average American bathroom. It's not normal, there are no two ways about it.

Is that a comment about the excessive size of American bathrooms? From what I can find, 6000/sq.km2 equates to something like 45 sq.m of living space per apartment.

It's not a comment on American bathrooms. There are people in Japan literally living in drawers.[0] Not even a joke. You're plan to "start ramping up immigration and allowing in those from cultures where having larger families is more of a priority" is quite frankly insane. I can't even call it naive as it's clearly drawn from a political belief that "immigrant = good" with no exceptions, all repercussions be damned, even in severely overpopulated countries.

These aren't even the smallest ones. There are ones even half the size of these.

My "plan"? How on earth did you read that into my comment...

And yes some of those dwellings are pretty cramped, but is it somehow worse than the situation in many Western cities where there are those reduced to living in tents on streets or under bridges etc.? The "official" Tokyo homeless figures may be questionable (supposedly less than 800 out of a city of 15 million) but having visited a few times I can't say I recollect noticing any significant number of homeless people.

By "plan" I meant simply "a method for achieving an end,"[0] not that you actually intend to act on that plan. Feel free to replace "plan" with "idea" if that is better.

I'm really confused by your comparison to the US again here: is the homeless problem in the US because of overpopulation as opposed to drugs and mental illness, for example? If so, then if US cities are overpopulated to the extent that the homeless level has gone up so much, Japan is most certainly even more overpopulated, and it's a forgone conclusion that the population should decrease. If the homeless problem in the US is not due to overpopulation, then how is the homeless problem in the US relevant to the overpopulation problem in Japan?

In any case, the US fertility rate is also low, at 1.64. So I think it's fair to say the cost of living, the largest of which is housing, plays a crucial role in the fertility rate. A family can't live in a cupboard, no matter how "accustomed to the idea" one may be. At the very least, most people wouldn't choose to start a family in a cupboard, and that is certainly reflected in the Japanese fertility rate.

and end up in a situation where 80% of the country is over 70 and cannot function? how is that better or short-lived?

My father was born in 1935, he's 87 going on 88 and takes a turn on roster once a week to deliver meals on wheels to the old people that struggle to get by.

Otherwise he potters on with his meetings on the organisational side of the local bushfire brigade and looking after his 15 km section of a 1,000 kilometre long bushwalking track that runs past not too far away .. when he's not splitting wood, fixing gates, etc.

He's not altogether unusual in the area, there's a lot of still active older folk about the place.

Can you expand more on how everybody over 70 cannot function?

that a great data set of 1. In Japan, men are statistically not expected to live past 81, so it's safe to say most of them are in deep decline after 70, a few years away from death.

Also, officially after 65 they can stop working, so who is even going to work in the whole country??

Data set of at least 2,000 within the immediate district .. read more carefully and I know the local demographics.

People here 'retire' early also - those that stay active with volunter work live longer.

Japan has an aging population, it's entirely possible that those that are aged and active can contribute to the care of those that require assistance.

well, we will find out soon enough. I think it will be pretty bleak and there is no going back unless they let people in.

Short lived because the population will decline until it reaches a sustainable level. Lets say 30-40 years.

how can the population possibly reach "sustainable" level (not sure what this word means in this context, im assuming non-decreasing?), when the fertility rate today is 1.34 (need 2.1) and plummeting? It's going to get worse the more old people they have, because old people can't have children. When the whole country is old, there will be no children, because who's going to make them, even if they have an odd sudden change of heart?

The old people die. The population rerurns to 2.1. Do you really think it will continue to go down forever? Do you not see the increadible overpopulation and housing costs in Japanese cities as the cause of low fertility? Why do you think there is something inherently "wrong" with Japanese people that can only be solved by foreigners?

There's a reason that when most people go to Japan they are in awe of the politeness of the people, the safety felt while walking down the street, and the overall cleanliness of the place.

Contrast this to your example, America (I am assuming you mean USA). While seeing rows and rows of homeless people is nothing new, today I saw a video of a homeless person slapping human faeces in the face of another homeless man.

There is more to this problem than just trying to maximise growth.
