What's with all this scaremongering around China gonna invade everything anytime soon? How many wars has China started?

In my lifetime I've only seen one major county besides Russia having a habbit of starting illegal wars whenever geopolitics doesn't go its way and it's not China.

Traditional threat to Hokkaido is Soviet tank battalions, not Chinese. It's roughly due east to Vladivostok and to south of Sakhalin island. Unless Russian Federation actually falls and these regions change hands into hostile entities, it should be okay. And there will be more important things to worry than continuing economical chip production if that happens.

Yes. But I will entertain the idea that Hokkaido is not defensible. Now, with Hokkaido not being defensible, please explain why it has been an Japanese territory since the 15th century?

Japan has a big army/"self-defence force", impenetrable terrain over most of its territory, and 45 tonnes of plutonium. Even if the defence treaty with the US vanishes, the probability of a foreign invasion is rather low.

"Once China solves the Taiwan problem"? Then I suppose Japan has nothing to worry about.

It depends what japan and korea will do to piss of China just to please their far away masters.

> Once China solves the Taiwan problem they're going to turn their sights on Korea and Japan.

China will not annex Japan or South Korea. As a Chinese person, I can assure you that this is not how our mindset works at all. Most of the Western media hype about this is deliberately designed to muddy the waters around the Taiwan issue. Taiwan is different: the vast majority of people there are ethnically Chinese, so reunification is seen as an absolute necessity. But historically, China has never been good at ruling non-Han peoples. Every non-Chinese group has always been viewed as a net burden. Take Myanmar as an example: even if China occupied it and gained a warm-water port, the price would be having to assimilate tens of millions of Burmese people. That cost is simply too high; no one in China wants to pay it. The Chinese way of thinking is that only after a group has been fully Sinicized (language, culture, identity) can they be considered “one of us.” So with South Korea and Japan, the real goal is to surpass them industrially and economically, to leave them in the dust on the factory floor and in the lab. When it comes to Japan in particular, the deepest desire in many Chinese hearts is for Japan to start a war first—so China can finally settle the historical score once and for all. But even in that scenario, turning Japan into “part of China” is not on the table. No one wants 125 million thoroughly non-Sinicized Japanese inside the country; that would be seen as an endless headache, not a prize.

If we aren’t already in a world war from China solving Taiwan as you say, we would be in one from China taking Korea or Japan.

What kind of line is "once china solves the taiwan problem"? You assume that they will take Taiwan. Have you not been privy to the utter embarrassment of a continental power trying to take Ukraine right now? China is very aware of the isolated situation Russia is now in. They have desire to be in that situation.

Noone is letting China "solve the taiwan problem" like you said.

Such inflammatory language.

The Soviets trivially took the Kuril Islands and they can trivially defeat Japan if they so desire. China's also really interested in Okinawa independence. Both countries have appealed to arguments on liberating indigenous populations to hint at future military action against Japan.

It's a future war zone through and through, especially now that their PM is LARPing as Hirohito reincarnate.
