Would Japan enter the European war for Germany?

Japan's alliance does not make its strategy subordinate to Berlin, while the recent Soviet-Japanese fighting illustrates how Asian commitments shaped the timing of European decisions.

Question

Would Japan enter the European war simply to support Germany?

Short answer

No; Japan would follow its own strategic interests, and the recent Soviet-Japanese fighting shows how Asian commitments could constrain European timing.

Notes

Japanese policy remains independent of German needs. Japan is unlikely to declare war merely to support Germany, even if British commitments elsewhere serve Japanese interests. The wider 1939 strategic calendar offers a parallel: the Soviet Union did not move into Poland until its fighting with Japan had ended. Alliance labels do not erase each state's independent wars, risks, and timing.
