Mr. Rozo Asano, President, Nippon Steel Tube Co.
He starts out saying that steel is the basic material in war. Japan gets its major supply of iron ore from Japan and somewhere else, but I can't understand what he says at that point.
He says there is no high-grade ore available in the main islands of Japan.
He says that the steel industry was dependent on merchant shipping during the war.
The “state of health” of Japan's steel industry was directly related to the actions of US submarines.
The net result was a gradual strangulation of their steel production, and that this had a negative impact on Japan's war abilities.
