I know the subject of Germany's occupation and reindustrialization was a point of contentious debate among Allied planners. Did a similar debate take place with regards to Japan? What was the scope and result of that debate? Was there a faction pushing for a greatly weakened Japan wholly dependent on American manufactured goods?
In short, yes, largely the same high-level policymakers (spearheaded by Henry Morgenthau, Secretary of Treasury under FDR and a key architect of some key foreign economic policies like Lend Lease) who believed that Germany should undergo military deindustrialization after the war believed the same about Japan. In both cases, steps towards such deindustrialization were implemented through the "Morgenthau Plan"—to a lesser degree in Japan than in Germany—but rather quickly reversed when the general consensus became that deindustrialization would probably cause more problems down the road than it would solve.
In the early years of the Japanese case (1945-47), it's also true that the US approach to reconstruction policy in Japan did not emphasize reindustrialization to a meaningful degree, focusing instead on dismantling the imperialist and militarist features of Japanese society while alleviating mass starvation and social unrest. It wasn't until early 1948, as an economic crisis ensued in Japan and US policymakers grew concerned about the potential for communism to gain influence in Japan and other economically troubled East Asian societies, that the US fully reversed course toward actively transforming Japan into an industrialized regional engine of growth.
