Rear Admiral Shigetarō Shimada and Vice Admiral Tadamichi Hirayama Min Tanaka push a plan to build a super-battleship, a bold project meant to symbolize Japan’s strength and resolve in a tense era. To test the idea, Yamamoto’s faction alongside Osami Nagano Jun Kunimura recruit Major Tadashi Kai Masaki Suda, an autistic mathematics prodigy obsessed with geometry, to critique the proposal and push for a tighter, smarter design.
Kai pores over copied blueprints, extrapolations from the Nagato-class design, and procurement data drawn from personal connections. He demonstrates that the steel needed for the new battleship would cost far more than Hirayama’s initial estimate, revealing a hidden financial flaw in the plan. In response, Hirayama admits that he misreported the cost to push the project forward, and reveals a controversial strategy: he planned to compensate shipbuilders by overpaying on future cruisers. When Kai identifies a flaw in the design itself, Hirayama withdraws the proposal, and the competing aircraft carrier initiative, supported by Yamamoto’s faction, is approved instead.
After the vote, Hirayama confides the deeper motive behind pursuing the battleship: he believes that Japanese militarism makes war inevitable, and that a symbol of Japan’s collective spirit—even at a great cost—could stiffen national resolve and force a surrender before invasion. Kai, a pacifist at heart, reluctantly agrees to help perfect the design, which ultimately becomes the Yamato-class battleship.
Two months after the attack on Pearl Harbor, Kai attends Isoroku Yamamoto’s inspection of Yamato. Even as he witnesses the ship in its gleaming, ceremonial moment, Kai knows its sacrificial fate and cannot join in the jubilation.
