SECTION II -- OVERVIEW
Born Takeda Harunobu in 1521 in Kai Province, he deposed his own father Nobutora at age 21 to take the clan and forge it into the most feared military machine of the early Sengoku.His rivalry with Uesugi Kenshin produced the legendary Battles of Kawanakajima (1553–1564), five engagements over a single river plain that became the defining samurai duel of the era.
His cavalry doctrine and fūrinkazan banner — 'Swift as the wind, silent as a forest, fierce as fire, immovable as a mountain' — shaped a generation of warlords.By 1572 he was driving on Kyoto with realistic ambitions of national power, having shattered Tokugawa Ieyasu at Mikatagahara, but died of illness mid-campaign in 1573, sparing Nobunaga what might have been his most dangerous foe.

SECTION V -- FIELD NOTES
[A]Kawanakajima Duel
At the fourth Kawanakajima in 1561, Uesugi Kenshin reportedly broke through the Takeda lines on horseback and struck at Shingen himself, who deflected the blow with his war fan — the most famous single combat of the Sengoku.
SECTION VI -- LEGACY & IMPACT
Shingen's cavalry tactics and clan administration set the gold standard of Sengoku-era warfare. His untimely death in 1573 reshaped the unification race, and the fūrinkazan banner remains an enduring emblem of samurai virtue.

Kawanakajima: The Greatest Personal Rivalry of the Sengoku
Five battles, twelve years, no decisive winner. The story of Takeda Shingen and Uesugi Kenshin's repeated meetings on a single Shinano river plain became, for the Japanese, the archetype of a rivalry between equals.

Salt for an Enemy: The Single Gesture That Defined Samurai Honor
In the winter of 1567, Uesugi Kenshin sent salt to Takeda Shingen — the man he had fought five battles against. Four hundred years later, the gesture is still taught in Japanese ethics classes as the highest example of just war.

Nagashino: The Day the Cavalry Died
On the morning of May 21, 1575, Takeda Katsuyori's elite cavalry charged into a three-tier line of three thousand Oda matchlocks. By sunset half of the Takeda's senior generals were dead and the army once called the fiercest of the Sengoku was finished.

Why Katsuyori Lost What Shingen Had Won
Compare the Takeda of Shingen with the Takeda of Katsuyori, and the largest difference is neither manpower nor talent but the diplomatic environment. Katsuyori inherited none of the alliance structure his father had built, and had to fight inside Nobunaga's encirclement.
