SECTION II -- OVERVIEW
Born in 1559 in Ōmi Province, Mitsunari rose through Hideyoshi's bureaucracy as a master of accounts, surveys, and supply — the unglamorous work that held the Toyotomi state together.He was Hideyoshi's most trusted civilian official by his thirties, a chief organizer of the Korean invasions, and an advocate of strict centralized administration.
After Hideyoshi's death in 1598 he became the natural rallying point for daimyō who feared Tokugawa Ieyasu's drift toward the shogunate.His coalition lost catastrophically at Sekigahara in October 1600 — undone less by Ieyasu's tactics than by the secret betrayals Ieyasu had spent months engineering.
Captured days later in the hills, paraded through Kyoto, and beheaded in November, he refused water laced with persimmon (then thought medicinal for prisoners) on the way to the execution ground, telling his guards: 'A great cause is not abandoned for the sake of one's stomach.

“A great cause is not abandoned for the sake of one's stomach.”
SECTION V -- FIELD NOTES
[A]The Persimmon Refusal
Marched in shackles toward execution, Mitsunari was offered water mixed with crushed persimmon — a folk medicine for digestion. He refused, saying persimmons were bad for the stomach. The guards laughed: 'You're about to die, what does your stomach matter?' He answered: 'A great man cherishes his life until the very last breath, because while life remains so does the cause.' The line passed into Japanese moral education.
SECTION VI -- LEGACY & IMPACT
Edo-period historiography demonized Mitsunari as a small-minded bureaucrat who started a needless war. Modern scholarship, especially since the 1990s, has rehabilitated him as a principled defender of legitimate succession against a usurper — a reading reinforced by the 2016 NHK epic Sanada Maru. His Sawayama Castle, razed in 1601, still draws pilgrims who climb the hill to see where he held court.

On July 17th, 1600, three months before Sekigahara, a Christian noblewoman who had been forbidden by her faith from suicide ordered her chief retainer to kill her with a long sword through a closed shōji. Her death changed the course of the battle she did not live to see.
