Japan attacks South Korea in 2022 in order to acquire South Korea's human capital

This requires ASBs to make this happen, so here goes: What if Japan attacks South Korea in 2022 in order to acquire South Korea's human capital? This logic would be the exact same one that some Russian nationalists use to justify Russia's Ukraine invasion this year. Just how easy/difficult would such a Japanese invasion have been? Just how much of an insurgency will the Japanese face? Just how many terrorist attacks? And what will North Korea and the rest of the world do in response to all of this?
 
Insurgency? This is the Taiwan problem times 2. It calls for an amphibious operation that makes D-Day look like a kiddie pool party. Japan has nowhere near enough means to fight this war with.
They would have better chances with North Korea lol, and they still don't have the numbers for that.

Japan can build up its navy, no? And its army as well, if necessary. And North Korea has nukes; South Korea doesn't.

I wonder if Japan can do a Molotov-Ribbentrop-style pact with North Korea in this TL where they will aim to partition South Korea between themselves. Can South Korea withstand a Japanese amphibious assault and a North Korean invasion at the same time? Though having both of these sides fully trust each other would be extraordinarily difficult, I suspect. Each of them might simply think that the other side wants to severely fuck them over.
 
It seems it's just really hard for first world powers to militarily conquer and occupy anything nowadays. The Americans struggled in the North Korean war. The Americans couldn't defeat farmers hiding in straw huts in Vietnam and gave up. The Americans spent three decades in the Middle-East struggling to beat goat-herders in mud huts before giving up. Russia is invading Ukraine and is struggling as well.

Japan might be able to claim some territory along the coasts but they would probably struggle to make large gains further inland. So after a few years of bloodshed for not much gain, the Japanese invasion would stall out and they would probably keep to whatever coastal holdings they had.

It would be interesting to see if China tries to get in on the action too. They could try to eat parts of South Korea (either directly or through their proxy in North Korea), knowing that the South Korean military would be divided between fending off a Japanese front and an invasion from the North. In such a scenario, the South Korean military could face total collapse. Perhaps the country becomes partitioned like Berlin? Any occupation would be plagued by a horrendous insurgency that would last decades.

Cannot build enough of it. We're talking an amphibious invasion force in minimum high hundreds of thousands plus means to move and supply it. And even that may not be enough.
Meanwhile North Korea has very few nukes and crappy delivery methods, while Japan has state of art BMD systems.

Yup. I think the best option for Japan would be to try get these two to fight a highly destructive war with each other first and then surprise invade the more exhausted side, and then use that as a staging area if things go well.
And all that of course excludes the issue of US leadership yelling expletives at both sides from over the ocean.
Also the potential of Chinese intervention is something Japan would not want to risk. Chinese have a proper nuclear arsenal and proper army with land access to the peninsula, so the amphibious invasion would have no chance of winning if that happens.

I am pretty sure South Korea is declining just as fast as Japan where population is concerned, and it might get even faster since living there is allegedly even worse than living in Japan due to the same cultural reasons.

Honestly they'd be better off if they joined forces and tried to colonize the Philippines.

With what army and fleet? currently South Korean Fleet could stand to Japan alone,and their army is better.
 
I think S Korea would defeat any invasion and also there would be the little problem of Washington stepping in hard against Japan as soon as they got over the shock.

As others have said both nations have serious demographic issues, albeit possibly not as bad in the longer term as China so killing a large part of your population trying to conquer a neighbour who also has a shortfall in young people sounds distinctly bloody stupid.
