Japan has a heavy shortage of workers [0], and it has been so for many years now. Your link cites the efforts from 2017, the reason wasn't some olive branch to humanity, Japan already was in dire need of working class people.

Right now the yen is so weak Japan salary look ridiculously low, there is the language barrier, and the low hanging jobs aren't great either (a ton in elderly care).

Their policies to restrict immigration will have few impact short term, as immigration is already slowing down and even Filinos, who have always been on the better side of immigration, are looking for better opportunities [1]. Longer term though, people will remember how it goes when Japan economy trends down, and the immigration going away might not come back even when the trend reverses. Especially as there will already be a probably better community built elsewhere.

To put that in perspective, US companies report similar rates of worker shortages in surveys [1]:

> The survey found that company size influenced hiring outcomes. Seventy-six percent of companies with 1,000 to 4,999 employees reported shortages, followed by 75% of firms with 5,000 employees or more and 74% of those with 250 to 999 employees. Among smaller firms, 69% of organizations with 50 to 249 employees, 66% with 10 to 49 employees and 61% with fewer than 10 employees reported hiring challenges.

I'm not saying that there isn't a shortage of labor in Japan - just that business owners are never satisifed with the amount of labor available at the wages they wish to pay. And it may not be an existential shortage of labor like a lot of commenters are saying. Especially with recent developments in AI and automation.

The declining birthrate in general does seem to be an existential issue if it cannot be stabilized. But it is hard to predict population trends long term (when I was growing up the big concern was overpopulation and China was running its one-child policy - now they are facing population decline).

The weak yen is also definitely an issue right now - but it's impossible to predict where it will be in the future.

So yes, Japan is facing real problems. And stricter immigration requirements likely will come at some cost to economic output. But if they feel it is necessary to protect their social welfare programs and cultural identity, then those tradeoffs are theirs to make. And all of the doom and gloom comments saying things like "it's suicide" feel like a bit of an overreaction to me when you look at the actual proposed changes.
