Jisaburō Ozawa
After the death of Admiral Mineichi Koga, Toyoda was appointed Commander-in-Chief of the Combined Fleet on 3 May 1944. In June of the same year, he drafted and implemented "Plan "A-Go"" which resulted in the decisive defeat of the Imperial Japanese Navy under the command of Admiral Jisaburō Ozawa in the Battle of the Philippine Sea. He followed with "Plan "Sho-Go"", which again resulted in another major defeat at the Battle of Leyte Gulf. Toyoda was aware that both plans were major gambles, but as the Imperial Japanese Navy fleet was running out of fuel and other critical supplies, he felt that the potential gain offset the risk of losing a fleet that was about to become useless in any event. In the end, however, Toyoda's aggressive defensive strategy did not pay off. Nonetheless, Toyoda continued with the same strategy, approving "Plan "Ten-Go"" to send the battleship on its one-way final mission to Okinawa.
