What caused Japan to invade Manchuria?

Answer 1

Full invasion. They just took everything over by force, with the warlord in Manchuria afraid of starting a war, and predicting the Japanese only wanted more "benefits" not complete annexation, he ordered his troops not to resist.

Answer 2

Cina and the USA broke an agreement of using the railway where Japan get their raw materials(coal and oil). Japan had an increasing population and needed to gain land so they invaded Manchuria as it was an easy target and they had a reason to do so. They then bombed Shanghai for the hell of it. LOL!

Answer 3

Japan invaded Manchuria in 1931-1933 because Japan was increasingly becoming overcrowded, due to its soaring population growth. It was believed that China could easily accommodate the overspill of Japanese civilians. Japan had also suffered heavily from the Depression, and as a result there was a great desire for the country to become self sufficient. Manchuria was a place of many Natural Resources such as wood and oil, that could easily help Japan in their quest for autarky. The Depression had also aggravated military expansionism, there was an increasing desire for a larger and stronger armed forces. However, it can be argued that the trigger cause of the Manchurian Crisis, 1931-1933, was the The Mukden Incident, when there was an explosion on the South Manchurian railway. This gave the Japanese military a reason to invade, however it can be argued that it was in fact the Japanese who had caused the explosion, which despite the fact that they gave themselves a reason to invade, it also indicates that the Japanese were already present in the country, prior to the explosion.

Answer 4

Disarmament policies were proven both unsuccessful and unrealistic. ;)
