Answer:
Japan wanted Germany to help them engage the Soviet Union on two fronts--reducing the Soviets' strength on either side.
Step-by-step explanation:
Japan, meanwhile, also sought an alliance with Germany in 1935. The goal of the partnership was to create a united threat against the Soviet Union and against communism in general. When Mussolini heard about the possibility of a German-Japanese pact, he wanted an alliance with Japan too. All hesitation ended when the League of Nations condemned Germany, Italy, and Japan for their aggression. The three "aggressors" decided to join forces, and the triple alliance was finalized in September of 1940.
