How Did Japan Benefit From The First World War

How did Japan benefit from the first World War? Japan wasn’t always a nationalist or militarist country before becoming a major power during World War I, Japan was a growing power in Asia and was becoming a major threat as a whole. As an impact, this started the Sino-Japanese War in 1894, which called for Japan to give up the Liaodong peninsula, Shandong Province, and the with the seizures Great Britain and France were able to take advantage of a weakened China and take hold of port cities.

This gave Japan the opportunity to expand its influence into Asia even further by Japan issuing the “Twenty-one Demands” to China for commercial privileges in Manchuria and was able to do this by demanding German colonial territory in China when its demands were ignored Japan declared war on Germany. After the declaration of war on Germany, Japan seized German Military bases on the Shandong Peninsula and its navy occupied Germany's South Pacific
