Daimyō of Kai Province; "The Tiger of Kai"
"As swift as the wind, as gentle as the forest, as fierce as fire, and as immovable as the mountain."
Shingen deposed his own father to take control of Kai Province and built the most feared cavalry force in Japan, fighting the rival warlord Uesugi Kenshin to an inconclusive standstill across five separate battles at Kawanakajima that became legendary for their scale and near-mythic single combat between the two commanders. His famous banner, reading *fūrinkazan* — wind, forest, fire, mountain — described a doctrine of alternating speed and immovability that made his armies extraordinarily difficult to predict. In late 1572 he finally marched west, ostensibly toward Kyoto, and shattered Tokugawa Ieyasu's army at Mikatagahara so completely that Ieyasu barely escaped with his life. It was the clearest evidence in the entire unification era that the Oda-Tokugawa alliance was not invincible, and had Shingen lived, the subsequent history of Japan might have gone very differently. He died of illness on campaign only months later, in the spring of 1573, and his death was concealed by his retainers for three years to prevent the Takeda domain from collapsing immediately. His son Katsuyori inherited the same fearsome cavalry and, without his father's caution, threw it directly at massed Oda gunfire at Nagashino two years later, destroying in an afternoon what Shingen had spent a lifetime building.
Did you know?
His death was kept secret by his retainers for three years — his generals continued issuing orders and holding audiences in his name to prevent rival clans from sensing weakness and attacking while the succession was unsettled.

The one clean defeat any of the eventual unifiers suffered in a major pitched battle, and Ieyasu kept a portrait of his own humiliated, terrified face painted afterward, reportedly to remind himself never to be so reckless again. Shingen's death from illness a few months later, on the march, removed the one man capable of beating Nobunaga's alliance outright — Ieyasu's survival here was closer to accident than victory.
