Japan is often mentioned in the Second World War, but what was Japan’s involvement in the First World War? In this article, we will understand why Japan got involved in the First World War (1914).
Japan entered the First World War alongside the Entente to conquer the German colonies. Japan had scarce natural resources and a growing population, so they were interested in other countries.
Their participation in the first war was in respect to the treaties signed with England. Their involvement was only in battles against the German colonies in East Asia in the Pacific Ocean and the German concessions in China.

After the Russo-Japanese War in 1905, Japan managed to gain respect among Western nations and grew as a power, forming several alliances in Europe.
The History of Japan in the First World War
In the First World War, Japan was part of the Triple Alliance. In November 1914, Japan helped England disarm the fleet of German cruisers in China.
By 1915, Japan decided to increase its participation in the war by sending anti-submarine troops to the Mediterranean Sea, assisting the English fleet in the search for German submarines.
After the First World War, due to scarcity and tensions between Japan and the United States, the country made numerous decisions that harmed various countries and themselves.

There were numerous wars and massacres between Japan and other countries in Asia. Among them is the famous Nanjing Massacre in 1937 when the Second Sino-Japanese War broke out.
Japan pressured China to meet a series of requirements imposed by Emperor Taishō, who sought to economically strengthen the Empire. The Western powers, suspicious of the actions of the Japanese Army, pressured Japan to withdraw its demands.
This created great tension between Japan and the West, leading Japan to switch sides and become an ally of Germany in the Second World War. In the end, this resulted in the attack on Pearl Harbor and the nuclear disaster in Hiroshima.
