第二次ロンドン海軍軍縮会議
In the aftermath of the First World War, the Washington Naval Treaty was drawn up in 1922 in an effort to stop an arms race developing between Britain, Japan, France, Italy and the United States. This treaty limited the number of ships each nation was allowed to build and capped the displacement of all capital ships at 35,000 long tons. These restrictions were extended in 1930 through the London Naval Treaty, however, in 1935 Japan and Italy would not agree to the Second London Naval Treaty for further armament control.
