In OTL, Japan made major gains against China in the 1st Sino-Japanese war, but due to Germany, France and Russia forced them to give Shangdong back to China and Mccarthur to Russia. The latter was later regained during the Russo-Japanese war, but it was quite costly. How could we have them gaining all this territory or even more without foreign intervention, and if so, what consequences would come out of this? No Russo-Japanese war? Early annexation of Korea? No Anglo-Japanese Alliance? No rise of extremism? Discuss.
