Soemu Toyoda
The American options were apparent to the IJN. Combined Fleet Chief Soemu Toyoda prepared four "victory" plans: "Shō-Gō" 1 (, "") was a major naval operation in the Philippines, while "Shō-Gō" 2, "Shō-Gō" 3 and "Shō-Gō" 4 were responses to attacks on Formosa, the Ryukyu Islands, and the Kurile Islands, respectively. The plans were for complex offensive operations committing nearly all available forces to a decisive battle, despite substantially depleting Japan's slender reserves of fuel oil.
