Oh hell yeah. Burma and New Guinea were awful for all the combatants but especially for the Japanese. Malaria, dysentery ravaged both the allies and the Japs. The difference was our medical corps could better handle it. We had quinine and morphine. The Japanese didn’t. We could evacuate our wounded. Theirs got a hand grenade to end their misery.
In Burma and New Guinea, US cargo aircraft were used to move large numbers of troops and to supply them.
The Japanese couldn’t do that.
You can see the French Generals looking at the successful use of cargo aircraft and thinking, “We can do the same at Dien Bien Phu.”
