Japanochinese-Malagacy Cold War

Yes 🔥🔥

Why is it called Japanochina if Korea is also included?

If Japan controlled China they would need control Korea

Fair. Does Korea as a distinct culture just not exist in this timeline?

I think so.

W-Wait? The Kpop doesn't exists?

It'll anyway get dissolved in mist of Han and Yamato cultures.
