If you are referring to the period immediately prior to WW2, I would say not that significantly. Japan was already a significant military power by that time, which is probably why Germany wanted them as an ally.

Initially after the Meiji Restoration in 1867 Japan relied on Western advisors to help with modernization and industrialization, but these advisors were from many countries such as Britain, the US, and France, in addition to Germany.

Imperial Japan thoroughly defeated China (1894-1895) and Russia (1904-1905) in wars on land and at sea.

Japan became a British ally in 1900 and fought on the side of the Allies in WW1, taking German possessions in the Pacific.

By the time of the Anti-Comintern Pact between Japan and Germany in 1936, Japan was already a major power, which was why Germany wanted to ally with them. I'm sure they cooperated in ways that were helpful for Japan, but I don't think it was a significant cause of the strength of Japan.
