Operation: Coronet, the Allied (primarily United States Army) invasion of Honshū at the Kantō Plain south of the Japanese capital Tokyo, was to begin on "Y-Day", which was scheduled for March 1, 1946. Coronet would have been even larger than Olympic, with 25 divisions, including the floating reserve, earmarked for the initial operations. (The Overlord invasion of Normandy, by comparison, had 12 divisions in the initial landings.) The U.S. First Army would have invaded at Kujūkuri Beach, on the Bōsō Peninsula, while U.S. Eighth Army invaded at Hiratsuka, on Sagami Bay. Both armies would then drive north and inland, meeting at Tokyo.
