Could the 1939 Soviet fighting justify mechanizing Japan's army?

Could Japan use its 1939 experience against the Soviets as a reason to mechanize the army?

Yes. Soviet tanks and artillery had defeated methods that previously worked, and Chinese artillery concentrations exposed similar weaknesses that Japanese officers understood.

A viewer proposes using the 1939 experience against the Soviets to argue for mechanization. Japanese methods emphasizing light mobile forces and mass attacks had failed against Soviet tanks and artillery. Chinese concentrations of artillery had exposed the same weakness, with the earlier battle described as a two-to-one Chinese advantage in total guns and three-to-one in effective numbers. Japanese officers understood that tactical skill could not reliably overcome a large disparity between artillery forces of comparable effectiveness. In the counterfactual, those experiences supply an argument for spending time on equipment and logistics before another war.
