Challenge: Make Japan weaker than Korea

Any PoD that can sufficiently make Korea "more powerful" than Japan?

Bonus points if Korea becomes moderate instead of ultra-conservative

Bonus cookies if Korea goes through a Meiji Japan-style industrialization.
 
The United States invades mainland Japan in 1945, resulting in a bloody decades-long occupation, massive death tolls, and destruction of most infrastructure.

Trivially, make Japan less powerful. Thwart the Momoyama unification of Japan and leave Japan stuck in Sengoku disunity.
 
Don't worry okmangeez, the updates are coming...;)

I think a concept is extended civil war era. Thus not only wouldn't there really be a Japanese invasion of Korea, the economy would be devastated.
 
You dont need a POD, it is happening right before us.

Before mid century Japan's population would have shrunk to the same level of the peninsula. Combined with the potential boom of post unification dividends, Korea is well on track to surpass Japan in overall GDP.

politically and militarily Japan is too gimped by the US and China that two Korea's combined military size already surpassed Japan in the 50s, and in the foreseeable future the overall military power of the peninsula will be much more powerful than Japan.

Though in reality none of this means anything because the whole region's military and economic system is underwritten by the US and China. At least in the 21st C. the relative strength of Korea vs Japan is a totally academic question anyways. (as everything will unfold under the auspices of US/China)
 
Nerfing Japan isn't all that hard as long as there is no unifier that gains the title of Shogun. Wanking Korea enough to become a Meiji-esque miracle state is a lot more difficult as long as it stands at the border of powerful empires (I.e. China, later Russia). Reaching Siam's level of modernization is more doable, especially without Japan trying to exert its imperial ambition on Korea.
 
"Post reunification dividends"? The hell? Reunification is going to be a vast pit of money that will take at least a decade or two for the South`s economy to recover from.

In the long run Korea has a lot going for it, especially being more open to immigration which will hopefully allow it to avoid the kind of demographic collapse that Japan is hurling towards but it`ll make life easier for the young or they`ll vote with their feet and immigrate.
 
Say that unification of Japan is severely delayed and that Commander Perry doesn't approach gunboat diplomacy.

What might be the effects of that on Japan, Korea, and Asia as a whole?

Severely delayed unification of Japan (c. 1600) = there may not even be a United States of America, let alone one powerful enough to play the game of diplomacy.
 
Mongol invasions of Japan succeed
The Japanese attack the Matthew Perry's fleet, causing the U.S to invade and possibly colonize Japan
No unification, no 'empire'
Possibly a Chinese Japan, but idk how it would be likely
Operation Downfall happens, along with multiple uses of atomic weapons on military, industrial, and civilian targets. Probably the weakest Japan possible
George Takei doesn't invade the Soviet Union

Have you been playing Red Alert 3 again? :p:p:p:p:p

Wait.. How so?

The first successful British colonies weren't even set up yet at 1600, which is around the time of the Battle of Sekigahara, which began the Tokugawa Shogunate. The very foundation of the United States had barely been set up, and Britain is still in the early Stuart period. It could be that an alternate Japan is more receptive to foreigners. And a lot can happen in the two hundred years between the Stuarts and independence.

Um.

That is certainly possible, but I don't know if it'll just make the USA disappear into the midst of history.

I mean, fractured Japan in OTL was either pro-foreigner or anti-foreigner. It won't be easy.

You could have a French America instead, or a continued Spanish dominance, or even a bunch of scattered American nations.
 
Have Joseon or some other ancient Korean kingdom be usurped and taken over by a barbarian conquest dynasty like the Yuan dynasty of China and have them expand along the Siberian coast to where Vladivostok would be allowing them a frontier to grow into and perhaps allowing them a couple successful conquests in and around Kyushu during the Sengoku period that would allow them to slowly swallow up Japan from the south and from Hokkaido, Sakhalin, and the Kuril islands to the North where Honshu would slowly be consumed.
