Did Japan participate in World War I?

Yes The Russo-Japanese War and the War between Japan and Germany were all World War I.

Yes, mainly in Asia, to contain Germany.

Participated, it was the Allies.

Japan entered World War I. The main purpose of Japan's entry into the war was to take over Germany's sphere of influence in China and then seize Germany's colonial (civil) territories in the Pacific.

In August 1914, Japan declared war on Germany.

On September 2, troops were sent to occupy Longkou, Shandong, China, and soon occupied Jinan to take control of the Jiaoji Railway. On 7 November, with the support of the British, Qingdao was captured.

At the same time, the Japanese navy Li Ruya went south to seize the Marshall Islands, the Mariana Islands, and the Caroline Islands, which were German colonies in the Pacific.

Due to the Entente's repeated requests for Japan to send troops to Europe to participate in the war, in March 1917, Japan sent three ships to the Indian Ocean and the Mediterranean, mainly responsible for escort.

During World War I, Japan did the following:

1) On July 28, 1914, World War I broke out. Japan issued an ultimatum on August 12 demanding that Germany surrender Jiaozhou Bay. On August 15, a full-scale attack on Qingdao was launched, and the Japanese army concentrated 50,000 men to storm Qingdao.

At that time, the total strength of the Germans in Jiaozhou (Qingdao) was only 4,200 and more than 3,000 combatants, but the Japanese were unable to attack it repeatedly, and finally it was difficult to take it with the help of the British.

2) In the Pacific, Japan dispatched its navy to attack the isolated German islands, occupying the Mariana Islands, the Marshall Islands, Truk Atoll, and other places. Since Europe and the United States did not have time to take care of Japan, Japan's influence even extended to the Hawaiian Islands, much to the annoyance of the Americans.

3) Japan repeatedly exchanged fire with the Austro-Hungarian Navy and German submarines in the Mediterranean, one destroyer was damaged by an Austro-Hungarian submarine, and one escort ship was sunk, ** dozens of people. Since then, Japan has successively increased its troops to the Mediterranean, reaching 18 ships at its peak, transporting 700,000 troops and a large number of supplies, winning high praise from Britain and France.
