On this day, 85 years ago, on September 27, 1940 (August 26, 1940 in the lunar calendar), Japan joined the Axis powers, Germany, Italy and Japan, and signed the Treaty of Tripartite Alliance. On September 27, 1940, Germany, Italy and Japan signed a 10-year military and economic cooperation treaty, establishing the uranium cores of Berlin, Rome and Tokyo. In the early days of the Second World War, the "Soviet-German Non-Aggression Treaty" was signed in 1939. For this reason, Japan suspended negotiations to conclude a military alliance with Germany and protested to Germany. But out of common interests, Germany and Japan resumed negotiations in Tokyo in 1940, and Italy joined. On September 27, the Treaty of the Tripartite Alliance of Germany, Italy and Japan was signed in Berlin. The treaty stipulates that Japan recognizes Germany and Italy's leadership in establishing a "new order" in Europe, while Germany and Italy recognize Japan's leadership in establishing a "new order" in East Asia. The three countries undertake to support each other through all political, economic and military means in the event of war between the contracting parties and other countries. The signing of this aggressive treaty marked the formal alliance of the fascist axis of Germany, Italy and Japan. The contradiction between Germany and Germany has reappeared, and the contradiction between Britain, the United States and Germany, Italy and Japan has also intensified day by day. The signing of this treaty also accelerated the process of joint opposition between the Soviet Union and Britain and the United States. At the same time as the treaty was signed, Japan invaded French Indochina. Although the French troops in Vietnam suffered heavy casualties, they still resisted tenaciously. Observers said that the bodies of the Japanese were piled high along the road. Due to the shortage of time, the Japanese army had to cut off the hands of the dead to be identified later.
