Germany had extended considerable military aid to China during the 1930s, which

Japan and China, the Germans declared their neutrality in the
Sino-Japanese conflict and attempted without success to mediate a
settlement. The Japanese in turn pressured Berlin to remove its
advisors from China and cancel its arms contracts. Chiang did everything
possible to cultivate German friendship, including endorsing the
Anschluss with Austria,
the end Japan proved too valuable an ally for Germany and, in
1938, Hitler ceased all military aid to China.

The Army minister, Itagaki
Seishiro, wanted a comprehensive alliance that would
go into effect. The Navy minister, Yonai Mitsumasa, wanted
scope of the alliance restricted to Russia and invoked at the
discretion of the signatories. The ambassadors to Germany and
Oshima and Shiratori, were in the ultranationalist camp and
exceeded their instructions in an effort to push through a
comprehensive alliance. The Cabinet deadlocked after a compromise

Relations between Japan and Germany suffered a severe blow when

direct violation of a secret protocol in the 1937 Anti-Comintern
that bound the signatories to "conclude no political treaties with

with enough freedom of action to win the support of the Navy.
The Tripartite Pact itself was signed on September 27, 1940. This pact recognized the German-Italian “new order” in Europe and the Japanese “new order” in greater East Asia. The three nations pledged themselves to make war on each other’s behalf against any intervening “power at present not involved in the European war or in the Chinese-Japanese conflict”, a clear reference to the United States, since the Pact specifically excluded Russia. Unsurprisingly, Japan's signing of the Tripartite Pact became a major point of contention with the United States leading to the Pacific War.
It seems clear that both Japan and Germany hoped the Tripartite
would act as a deterrent to the United States. However, Japan had
occupied northern French
Indochina just a few days before the pact was signed, and
combination of events was viewed in the United States as a
producing the opposite effect from what was likely intended.
On 13 April 1941 Japan signed a non-aggression pact with Russia, which cleared the way for a move against Southeast Asia. Less than three months later, Germany launched its massive invasion of Russia, on 21 June 1941. Once again Japan found its policy towards Russia at odds with the actions of its principal ally. Japan chose to honor the nonaggression pact throughout the Pacific War, until it was renounced by Russia in August 1945.

the Axis never
really trusted each other, and their policy towards Russia was
completely uncoordinated in spite of the obvious value of
policy towards the central Eurasian power.
Racism likely played a role. While Italian fascism was

Pearl Harbor but then not
again for over a year. A Japanese proposal to
attack Madagascar in 1942 was strongly opposed by the Germans as
infringement on the German sphere of operations (the dividing line
at 70 degrees east longitude.) Hitler is reported to have stated
March 1942 that he would enjoy lending Britain twenty divisions with which to drive
the Japanese in the Far East. Allied prisoners of war
working at the docks at Singapore
later reported that a U-boat crew had come to attention and
saluted them as they were marched past by their Japanese captors.
Some idea of how artificial the alliance was can be
from a communication on 26 July 1941 from the Thai prime minister to
minister (Prange 1988):
The primer minister of Thailand advised the American minister that the German military attaché had warned him against "going too far" with Japan because "you cannot trust Japan." The attaché added ominously that Germany would "settle with Japan after she has won the war in Europe."
Curiously, Thailand did not immediately sign the Tripartite Pact
even after she
was pressured into entering an alliance with Japan and declaring
Britain and the United States.
It is difficult to disagree with Gaddis Smith (1985) that "Axis
diplomacy was one of the greatest assets enjoyed by the Allies."
