I still think Yamashita got a bum deal by being hanged.
Did you know that he executed Japanese soldiers for killing civilians in Malaya? I imagine you are talking about his problems with command authority vis a vis the IJN.
Homma was railroaded, too, although he was shot rather than hanged after a direct appeal by his wife to MacArthur. He ordered that the Bataan marchers be treated in accordance with the Geneva Convention, despite Japan's rejection of the Convention as an unequal treaty, and furious opposition from powerful officers who completely circumvented his orders, even to the extent of ordering (without effect) the execution of all Allied POWs from Bataan and Corregidor.
The logic of Japanese rejection of the Geneva Convention is interesting. There will never be Japanese POWs, since all Japanese will die rather than be captured, so the treaty proposes unequal responsibilities.
One version of Homma's last moments includes the line, "If I were afraid of guns, I probably would have found a different line of work."
Filipinos would disagree.
