Japan became a member of the League of Nations in 1919 as one of the fourty-two founding members.
They soon left on March 27th,1933.
The United States never became a member of the League of Nations. The people thought that if they joined, they would be forced to join in another nations conflict.
The league of nations sat back as Germany, Japan and Italy took control of what they believed to be theirs. The era of appeasement allowed the countries to become problems for the world.

The League of Nations failed to effectively deal with the Japanese invasion of Manchuria in 1931 due to various factors. Firstly, several major powers, including Britain and the US, were hesitant to take strong action against Japan as they had their own economic and strategic interests in the region. Additionally, the League lacked enforcement mechanisms, and member states were not willing to commit military forces to intervene. Ultimately, the League's inability to impose meaningful sanctions or halt Japanese aggression undermined its credibility and effectiveness.
