Japan’s Imperial Army had lived off the land, so to speak in China, Mongolia and Korea. In fact, the Japanese islands received foodstuffs, raw materials and even dismantled factories from these countries in the 1930s. Their merchant marine was never as developed as the US.
I don’t disagree that Japanese forces lived off the land and captured foodstuffs and materials (some of them managed to well after the end of the war). Neither do I disagree that she had an inadequate merchant fleet. That was one of her fatal weaknesses which was aggravated by her failure to hit our sub pens when she attacked us. I guess where we differ is your assertion that she “ignored” the importance of logistical support. Nimitz’s strategy was largely designed to isolate Japans forces when possible and allow them to wither and starve.
