They brought him through the streets of Kyoto in a large open crate, wearing a red and white short-sleeved kimono, an iron ring around his neck. The crowds came out to stare, to jeer, to witness. This was the point.

Ishida Mitsunari had not always been a great man's enemy. He had been a great man's most devoted servant. The story of how he came to Toyotomi Hideyoshi's (Toyotomi Hideyoshi) attention had become famous throughout Japan: a 13-year-old temple boy serving tea to an important visitor, adjusting each cup with quiet thoughtfulness — the first cup large and lukewarm, easy to drink quickly for a thirsty man; the second smaller and warmer; the third small and hot, for savoring. Hideyoshi saw the boy's attentiveness and recruited him on the spot. Mitsunari rose from temple servant to administrator of the most powerful domain in Japan, running Hideyoshi's finances and logistics with cold precision. He was not a great general. He knew it. He served as the mind behind greater swords.

When Hideyoshi died in 1598, he left behind a five-year-old heir, Toyotomi Hideyori, and a council of regents to govern until the boy came of age. Mitsunari believed, with the absolute certainty of a man governed by 義 (gi) — righteousness, duty to principle — that his obligation was to protect that heir against anyone who might seize the moment. The man he feared most was Tokugawa Ieyasu, 57, who moved through the post-Hideyoshi world with calculated patience, making alliances, arranging marriages, positioning his pieces.

Mitsunari organized the opposition. He assembled a Western Army from lords who shared his alarm or his resentment, and on October 21, 1600, at the crossroads of Sekigahara, the two sides met. The Western Army had the numbers. They had the position. And then, mid-battle, Kobayakawa Hideaki switched sides. The betrayal was catastrophic and possibly pre-arranged. The Western Army collapsed.

Mitsunari fled the battlefield around midday, escaped into the mountains north of Sekigahara, and hid for two weeks. He was eventually captured by Tanaka Yoshimasa, a former friend, and delivered to Ieyasu.

On November 5, 1600, Mitsunari, Konishi Yukinaga, and the Buddhist monk-diplomat Ankokuji Ekei were paraded through the streets of Osaka with iron rings around their necks and transported to Kyoto for the same humiliation. The public parade was deliberate — a ceremony of degradation, designed to let ordinary people see the faces of the defeated and understand who had won.

On November 6, 1600, the three men were brought to Rokujo-ga-hara (Rokujō-ga-hara), the dry riverbed of the Kamo River east of Kyoto, a traditional site of public execution. And there, Ieyasu delivered his final message.

They were not allowed seppuku (seppuku). They were beheaded. The distinction was not ceremonial; it was a statement of identity. Seppuku was the death of a samurai — a controlled, honored, self-determined act. Beheading at a public execution ground was the death of a criminal. Ieyasu was not merely killing his enemies. He was erasing their warrior status, declaring retroactively that they had never deserved it.

Konishi Yukinaga had commanded the vanguard of the Korean invasion in 1592, racing to be the first Japanese soldier to set foot on Korean soil at Busan. He had been one of the great field commanders of his generation. He was also a devout Catholic convert, baptized as Agostinho, and his faith presented a crisis. He refused seppuku explicitly: suicide was a mortal sin, and he would not die in mortal sin. He asked that a priest be permitted to hear his final confession. No priest was allowed.

Ankokuji Ekei was a Rinzai Buddhist monk who had spent decades as a diplomat for the Mori clan (Mori-ke), negotiating between great powers with remarkable skill. He had written a letter in 1577 — more than twenty years earlier — predicting Hideyoshi's rise to supreme power with uncanny accuracy. He had prophesied correctly once. He could not prophesy his own salvation.

Before the execution, tradition holds that Mitsunari was offered a persimmon to eat. He refused, saying it was bad for his stomach condition. An onlooker reportedly laughed: you are about to die — what does your stomach matter? Mitsunari's answer, if the story is true, reveals the man entirely: a person of ambition must always take care of his body. He was 41 years old and had no illusions about the next few minutes. He simply refused to stop being himself.

The three severed heads were mounted on stakes and displayed at Sanjo Bridge (Sanjō-bashi), the eastern terminus of the Tokaido road — the most-traveled entrance to Kyoto in all of Japan. Every merchant, pilgrim, soldier, and diplomat who entered the city in the days and weeks that followed walked past them. The message was not for the dead men. It was for everyone still living, still choosing whose side to be on, still deciding what kind of loyalty was safe.

Three years later, Ieyasu received the title of Shogun. The dynasty he founded ruled Japan for 265 years.

Mitsunari's hometown of Nagahama still celebrates the three-cups-of-tea story — the Sanken-Cha (三献茶, Sanken-Cha) tradition — as a model of attentive hospitality. He is remembered there not as a traitor or a criminal, but as a man of principle who served faithfully and lost everything for it. The tension between 義 (gi) and pragmatism runs through all of samurai history. He is its most extreme embodiment: the last man to die for the Toyotomi cause before the cause died with him.
