“The results of …. mining was so effective against the shipping that it eventually starved the country. I think you probably could have shortened the war by beginning (mining) earlier
“Mine warfare, in short, was merely another phase of air warfare.”
“Many ship casualties thought to be from submarine attack were actually due to mines.”
“I think the planes used in mining were more effective than an equal number used in bombing.”

Taken from the consensus of opinion of all Japanese mine experts as presented by Captain Kyuzo Tamura (later Admiral) at the U.S. Strategic Bombing Survey Conference (1945). The Vice Chairman of the conference was Mr. Paul Nitze, later Secretary of the Navy and Defense, and the interrogator was Commander Tom Moorer, later Chief of Naval Operations and Chairman of the Joint Chiefs of Staff. The mine effectiveness referred to was the 12,500 mines planted by B-29s in the Japanese home waters in the final five months of the war.
