A quick correction, Japan was a member of the Entente, not Central Powers, during WWI. The French, British, and American decision to not award Japan with much after the war was actually one of several reasons the relationship soured.

During WWII, the general answer is no. In fact, Germany’s decision to declare war on the US after Japan’s declaration led Germany to confront the US earlier than it probably would have otherwise. This is probably the biggest impact of the mutual defense pact (which didn’t actually oblige Hitler to declare war).

The two did not conduct operations in tandem, nor did they pursue shared strategic goals—they had none, aside from the broad aim of defeating the Allies. Whether the two could have worked together to any significant effect is questionable, since Japan declined to attack the Soviets.

To the extent the alliance did offer any benefits, they were primarily diverting Allied resources, demanding the Allies fight in the West and the Pacific and spend more on escort ships. This impact was limited though—they would have been diverted anyway and were fighting separate wars.

Worse still for the Axis, the Tripartite Pact did not lead the Soviets to keep significant forces on the Manchurian/Korean border. Japan signed a neutrality pact with SU in early 1941, which in addition to the dismal Japanese performance during the border war, gave the Soviets the confidence to bring most all of their Siberian forces west. The German leadership was in quite for quite a shock after they thought they had broken the Soviet army in early and mid summer 1941 and instead ran into professional forces.
