The Tripartite Pact

27 Sep 1940


ww2dbaseOriginally signed by Germany, Italy, and Japan, the Tripartite Pact was a typical European-style mutual defense treaty between the signatory nations. The treaty would call upon all three nations to unite against any aggressor who had violated the sovereignty of any of the three nations, not including nations that were already engaged in war with any of the three nations. It was not difficult to see that, given the international political situation at the time, the Tripartite Pact was signed with the intention to force the United States to remain isolationist and out of WW2 which had already been waging for an extended amount of time in Europe, northern and eastern Africa, and China.

ww2dbaseA summary of the Tripartite Pact is as follows:

ww2dbaseARTICLE 1. Japan recognizes and respects the leadership of Germany and Italy in the establishment of a new order in Europe.

26 Sep 1940 In the late evening, the German ambassador in the Soviet Union shared the news that Japan was about to join Germany and Italy in a military alliance.

I think if Japan would attack Russia from the far east it would easily contribute to the success of Operation Barbarossa, the German name for the invasion of Russia. Russian spy Richard Sorge, was successfully entered German embassy in Japan. He had succeeded in persuading the Japanese military to move into the south not in the far east. When he reported to Kremlin that Japanese are going to attack in the south Russia withdrew her several division from the far east and sent them to the crucial Moscow front.
Those fresh troops halted and moved back the German army of Von Bock near Moscow. For the first time in the war Germany army moved back.

The Tipartite pact signed September 1940

The pact was designed to provided political, economic, military and technical cooperation between Germay, Italy and Japan.
Exchange of raw materials, equipment, with technical assistance and personnel most of the material was sent by ship, but the Axis
had difficulties due to Allied submarines and naval ships.


The Allies were catching the Axis ships thanks to MAGIC decrypts. Germany started to transport material via the Trans-Siberian Railroad, but later ceased when the Germans invaded the USSR in June 1941 and the USSR became an Ango-American Ally, the Japanese
did't want provoke the USSR.


The Germans and the Japanese were forced to fly cargo and personnel by air across Russia to Japan. This operation was without cost aircraft became lost, were intercepted by Soviet aircraft, or disappeared over the vast area of the USSR.

Tachikawa Ki-77 was a long range transport
the aircraft was lost in 1943 over the
Indian Ocean possibly to RAF fighters on its
way from Singapore to Berlin.
The Germans used the Fw 200 Kondor or the Junkers Ju 290 four-engine transports,
KG 200 continued to fly its last missions up to the end of the war in Europe May 1945.

If the air link was difficult, shipping by sea was just as dangerous, Axis shipping losses were high due to submarines and naval ships. Ships traveling each way to and from
Europe and Japan faced Allied attacks and by 1944 very few Axis ships arrived in France.
Submarines were used, but they could only carry a limited amount of cargo and like the surface ships, they were hunted down and sunk


One of the problems in cooperation between the Germans and the Japanese was the price the Germans wanted for various technology
and technical assistance that was payable
in Gold or Reich Marks Please!...


Sometimes cooperation was largely theory the Germans were pressuring the Vichy French for rubber, and the Japanese found themselves in competition in their own back yard, with the Germans for Thailand's rubber.


Italy surrendered to the Allies in 1943. Germany was still cooperating with Japan, but with the USSR attacking from the East, and the Western Allies attacking from the West this brought and end to any real meaning and effectiveness to the treaty.
By 1944/1945, Germany and Japan were really fighting seperate wars.


Each country listed above surrendered to the USSR or the Western Allies in 1945.

(Reorganized National Government of China) Nanking Government: under Japanese control. Manchukuo: Japanese controlled.
Thailand: Japanese ally and controlled

"The only thing worse than having Allies,is not having them."

-Winston Churchill-

Was there ever any real cooperation between
Germany and Japan, was the Tripartite Pact
used to further their own military and political moves. Adolf Hitler never told the Japanese about his non-aggression pact with the Soviet Union, until two days before it was signed.
The Japanese didn't tell the Germans about
their neutrality pact with the Soviets, and the attack on Pearl Harbor came as a swift surprise to the Germans. Hastily arranged meetings on joint warfare agreements brought few measures.


The German Navy refused to share weapons and equipment technology with the Japanese until 1944 only after Adolf Hitler intervened the
Japanese held back from join-operations with the German in the Indian and Pacific Ocean
a lack of cooperation, racial arrogance by both sides, led to language and logistic difficulties nothing came of any real naval coooperation.


The term "Axis" was never an official term
for any of the various Alliances that both Nazi Germany, Italy and other countries formed. The term was coined by Mussolini for the German-Italian Pact that was known as the (Pact of Steel)

Perhaps it should be mentioned the Tripatite Pact was a public relations and political disaster for the Axis. It was designed to intimidate the United States. It certainly terrified many Americans because everybody knew to whom it was directed. But instead of intimidating it galvanised, helping to change the psyche of many Americans into accepting the necessity of urgent rearmament.
