Tokugawa Ieyasu became Japan's most famous warrior leader. A rebel, a unifier and the greatest Samurai general of them all whose achievements would match those of Caesar and Napoleon. He was as cunning as he was brave, and he founded a dynasty which would rule Japan for 250 years and whose ruthless philosophy of loyalty and sacrifice would shape it until our modern age. The story starts as the Taiko, Lord of Japan, dies. Ieyasu, then a powerful Samurai warlord, attempts to outmanoeuvre his enemies to grab power. The game of cat-and-mouse finally implodes in civil war, as vast armies clash over the future of Japan. Finally, on 21 October 1600, Ieyasu confronts two other armies in what became the biggest Samurai battle in Japanese history. During this decisive battle and at a moment when victory or defeat hung in the balance, he gambled everything on an act of almost reckless daring. This is also a story of a love for a reckless son, betrayal, redemption and that against insurmountable odds the belief in becoming Shogun - the military and political leader of his people.
