What Made the SAMURAI of Aizu Refuse to Surrender?

September 1868, and the world is changing faster than anyone can comprehend. Steam engines are replacing horses, rifles are replacing swords, and in Japan, an entire way of life—one that has existed for over seven centuries—is about to die in a single, devastating siege. But some stories aren’t just about winning or losing. Some stories are about choosing how you want to be remembered when everything you’ve ever believed in is crumbling around you.

The Domain of Aizu sat in the mountains of northern Japan, a place where time seemed to move slower, where cherry blossoms still mattered more than factory smoke, and where the word of a samurai was worth more than gold. For generations, the Matsudaira clan had ruled here, maintaining the old ways, the honorable ways. Their castle, perched on a hill overlooking the town of Wakamatsu, wasn’t just a fortress—it was a symbol of everything that made Japan beautiful, traditional, and proud.

To understand what made Aizu special, you have to understand what Japan was like in 1868. For over two centuries, the country had been locked away from the world under the Tokugawa shogunate’s isolationist policies. No foreigners were allowed in, no Japanese were allowed out, and the social order was rigid as stone. Samurai ruled, farmers fed them, artisans made their tools, and merchants—though they often grew wealthy—remained at the bottom of the social hierarchy. It was a world where your birth determined your destiny, where honor mattered more than wealth, and where the way of the warrior, bushido, wasn’t just a philosophy—it was the law of the land.

Aizu had always been more traditional than most domains. While other regions began to question the old ways, Aizu doubled down on them. Their samurai were trained not just in swordsmanship, but in the classical arts—calligraphy, poetry, the tea ceremony. They believed that a true warrior wasn’t just someone who could kill, but someone who could appreciate beauty, who could find meaning in the smallest gesture, who could write a poem about cherry blossoms one day and die for his lord the next.

The Matsudaira family had a special relationship with the Tokugawa shoguns—they were related by blood and bound by centuries of loyalty. When other domains began to whisper about opening Japan to foreign trade, about adopting Western technology and abandoning the feudal system, Aizu remained steadfast. They were the shoguns’ most trusted allies, the guardians of tradition in a world that seemed determined to abandon everything that made Japan unique.

But by 1868, Japan was tearing itself apart. The Shogun, the military ruler who had governed Japan for centuries, was losing his grip on power. A young Emperor Meiji, backed by progressive samurai from domains like Satsuma and Choshu, was demanding change. They wanted Japan to modernize, to open to the West, to abandon the feudal system that had defined the nation for so long. Most domains had already submitted to this new imperial government. But not Aizu. Never Aizu.

Lord Matsudaira Katamori, the daimyo of Aizu, had served as the Protector of Kyoto, defending the old shogunate system with unwavering loyalty. When the political winds shifted and the imperial forces branded him a traitor, he faced an impossible choice: submit to the new government and abandon everything his ancestors had died for, or fight a war he couldn’t possibly win.

He chose honor.

But here’s what makes this story extraordinary—it wasn’t just about one man’s pride. When Katamori decided to resist, he wasn’t just committing himself to death; he was asking his entire domain to die with him. And they said yes. Every samurai family, every retainer, every soldier in Aizu looked at their lord and essentially said, “If you’re going to hell, we’re coming with you.”

The imperial army that marched on Aizu in the autumn of 1868 was massive—over 50,000 troops armed with modern rifles, artillery, and Western military tactics. They had British advisors, advanced weaponry, and the backing of a government that controlled most of Japan. Aizu could field perhaps 5,000 defenders, many of them armed with swords and outdated matchlock rifles. It was David versus Goliath, except David forgot to bring his slingshot.

But the numbers tell only part of the story. What made Aizu’s last stand legendary wasn’t the size of their army—it was who made up that army. Because when the siege began, defending the walls weren’t just seasoned warriors. There were teenage boys, some as young as fifteen, who had trained their entire lives for a moment like this. There were women who had learned the art of the naginata, the curved blade, and refused to hide while their brothers fought. There were elderly samurai who could barely lift their swords but wouldn’t miss their final battle.

Among them was a young woman named Nakano Takeko, twenty-one years old and trained in the deadly art of naginatajutsu since childhood. When the imperial forces approached, she didn’t retreat to safety—she organized the women of Aizu into a fighting unit that would become known as the Jōshitai, the Women’s Corps. Picture this: a samurai woman, her hair tied back in the traditional style, gripping a seven-foot naginata blade, looking out at an army that outnumbered her forces ten to one. And instead of fear in her eyes, there was something else. Something that would make the enemy remember her name for generations.

Takeko wasn’t just any warrior—she was a master of her craft, trained by some of the finest martial artists in Japan. Her weapon, the naginata, was perfectly suited for a woman warrior. The curved blade at the end of a long wooden shaft gave her reach and leverage that could match any man with a sword. But more than her skill with weapons, what made Takeko extraordinary was her understanding of what this battle represented. She knew that if Aizu fell, the age of the samurai woman—the onna-bugeisha who had fought alongside men for centuries—would likely die with it.

The women who followed her into battle came from every level of society. There was her younger sister Yuko, barely eighteen but already skilled with both sword and naginata. There were the wives of samurai who had learned martial arts as children, not as a hobby but as a necessity in a world where your home might become a battlefield at any moment. There were servants and farmers’ daughters who had never held a weapon before but refused to hide while their domain was under attack.

What many people don’t realize is that female warriors weren’t unusual in Japanese history. For centuries, samurai women had been expected to defend their homes when their husbands went to war. They learned not just the naginata, but also the kaiken—a short dagger that every samurai woman carried, both as a weapon and as a means of preserving her honor if capture seemed inevitable. The women of Aizu weren’t breaking tradition by fighting—they were upholding it.

But the most heartbreaking defenders were the Byakkotai—the White Tiger Unit. These were teenage boys, aged sixteen to seventeen, sons of Aizu samurai who had been trained since childhood in bushido, the way of the warrior. Their leader was a boy named Iinuma Sadakichi, barely old enough to grow facial hair but carrying the weight of eight centuries of samurai tradition on his shoulders. When the siege began, these boys took their positions on the castle walls, knowing that this would likely be their first and final battle.

The siege of Aizu began in earnest in late September 1868, and from the very first day, it was clear that this wasn’t going to be a typical military campaign. The imperial forces, expecting a quick surrender once the defenders saw the overwhelming odds, instead found themselves facing an enemy that seemed to welcome death. Every assault on the castle walls was met with desperate resistance. Every breach was sealed with the bodies of samurai who threw themselves into the gap.

What the attackers couldn’t understand was that for the defenders of Aizu, this wasn’t really about politics or territory. This was about proving that some things—honor, loyalty, the bonds between lord and retainer—were more important than life itself. Every samurai in that castle had been raised on stories of legendary warriors who chose death over dishonor, and now they had their chance to join those legends.

The fighting that raged through those first weeks of October was unlike anything Japan had ever seen. This wasn’t the ritualized combat of earlier samurai conflicts, where individual warriors would call out challenges and fight single combat. This was modern warfare—artillery shells exploding against ancient stone walls, rifle volleys cutting down charging swordsmen, the acrid smoke of gunpowder mixing with the sweet scent of cherry blossoms.

The castle’s defenders developed tactics that amazed even their enemies. They would wait until imperial forces approached the walls, then suddenly appear at the battlements to rain down arrows, stones, and even boiling water. Samurai who had spent their lives perfecting the art of sword fighting adapted quickly to firearms, becoming expert marksmen who could pick off enemy officers from incredible distances.

But for every small victory, the reality of their situation became more apparent. Food supplies were running low. Ammunition was even scarcer. Wounded defenders couldn’t be properly treated because medical supplies were reserved for the most critical cases. Worst of all, every day brought news of more domains surrendering to the imperial government, leaving Aizu increasingly isolated.

The turning point came in early October, when imperial forces managed to breach the outer defenses and fighting spilled into the streets of Wakamatsu itself. The Byakkotai unit, stationed on a hill called Iimori-yama overlooking the town, watched in horror as smoke began rising from the direction of the castle. From their position, it looked like their lord’s stronghold was burning, like everything they had sworn to protect was already lost.

What these boys couldn’t know was that they were witnessing one of the war’s cruelest ironies. The smoke wasn’t coming from the castle at all, but from the town below, where imperial forces had set fire to buildings to flush out defenders. The great stronghold of the Matsudaira clan still stood, its white walls gleaming in the autumn sunlight, its defenders still manning the walls. But from Iimori-yama, surrounded by smoke and chaos, it looked like the end of everything they held sacred.

Here’s where the story becomes almost unbearably tragic. These teenage boys, seeing what they believed was the fall of their castle, made a decision that would echo through Japanese history. Led by Iinuma Sadakichi, twenty members of the Byakkotai drew their swords not to fight the enemy, but to perform seppuku—ritual suicide—rather than live with the shame of their lord’s defeat.

Picture this scene: twenty teenagers, boys who should have been worrying about their first loves or their studies, instead kneeling in a circle on a hilltop, preparing to die for honor. One by one, they drew their short swords across their bellies, falling forward as their closest friends served as their seconds, delivering the final, merciful blow. Only one boy, Iinuma Sadakichi himself, survived the suicide attempt, rescued by local villagers who found him still breathing among his dead comrades.

The cruel irony? The castle wasn’t actually burning. The smoke they had seen was from buildings in the town, not the main stronghold. Their lord was still fighting, still alive, still in need of their service. They had died for nothing—or perhaps, they had died for everything that mattered to them.

The ritual of seppuku itself tells us everything we need to know about these boys and the world they lived in. This wasn’t just suicide—it was a sacred act, a way of taking control when everything else had been stripped away. The proper way to perform seppuku required incredible courage. The warrior would kneel in the formal seiza position, compose a final poem if there was time, then draw his wakizashi—the short sword—across his abdomen in a horizontal cut. A trusted friend, acting as kaishaku, would then deliver a swift blow to the neck to end the suffering quickly.

For these teenagers, choosing seppuku wasn’t about despair—it was about agency. In a world where they had lost control of everything else, they could still control how their story ended. They could still choose honor over survival, dignity over defeat. Their deaths would tell the world that Aizu had raised warriors, not just soldiers, men who understood that some things were worth dying for.

But imagine the weight of that decision for boys who had barely begun to live. Iinuma Sadakichi, kneeling among his friends as they prepared to die, wasn’t thinking about political theory or military strategy. He was thinking about the stories his grandfather had told him about legendary samurai, about the poems he had memorized, about the oath he had taken to serve his lord with absolute loyalty. In that moment, those abstract concepts became more real than the blood on his hands or the smoke in his eyes.

But the siege wasn’t over. For another month, the remaining defenders held out in Tsuruga Castle, their situation becoming more desperate with each passing day. Food ran low, ammunition dwindled, and the walls that had once seemed impregnable were pounded to rubble by imperial artillery. Lord Matsudaira Katamori, watching his domain and his people suffer for his decision to resist, faced the terrible reality that every day he held out meant more death, more destruction for the people he had sworn to protect.

Nakano Takeko, meanwhile, had become a legend among both the defenders and attackers. Leading her Women’s Corps, she fought with a ferocity that amazed even seasoned warriors. But on October 16th, during a sortie outside the castle walls, she was struck by an imperial bullet. As she lay dying, she made a final request to her younger sister Yuko, who was fighting beside her: cut off her head and bury it so that the enemy could never parade it as a trophy.

Think about that for a moment. A twenty-one-year-old woman, bleeding to death on a battlefield, her final thoughts weren’t about her pain or her fear, but about ensuring that her enemy couldn’t dishonor her memory. Yuko, tears streaming down her face, granted her sister’s request, later burying Takeko’s head beneath a pine tree at Hōkai-ji Temple, where a monument stands to this day.

The end came on November 6, 1868, after a siege that had lasted over a month. Lord Matsudaira Katamori, looking out at the ruins of his castle and the bodies of his loyal retainers, made the hardest decision of his life. He would surrender. Not because he feared death—he had proven that already—but because every day he held out meant more suffering for the people who depended on him.

The surrender ceremony was heartbreaking in its dignity. Katamori, dressed in his finest robes, presented himself to the imperial commanders with the same composure he had shown throughout the siege. He offered his own life in exchange for mercy for his surviving retainers and the people of Aizu. The imperial forces, perhaps moved by the extraordinary courage they had witnessed, spared his life but exiled him from his ancestral domain forever.

But here’s what makes this story truly remarkable—the legacy it left behind. The siege of Aizu didn’t just end a rebellion; it created a mythology that would shape Japanese culture for generations. The image of the Byakkotai boys choosing death over dishonor became a symbol of perfect loyalty. Nakano Takeko became an icon of courage and determination. The entire siege became proof that there were still people in the world who valued honor more than life.

In the years that followed, as Japan transformed itself into a modern industrial power, the story of Aizu’s last stand took on an almost sacred quality. The Meiji government, perhaps feeling guilty about the destruction they had caused, eventually pardoned the domain and even honored some of its defenders. Monuments were built, stories were told, and the sacrifice of Aizu became part of the national consciousness.

The irony is profound: in losing their final battle, the samurai of Aizu won something far more valuable than victory. They proved that in a world increasingly driven by practical considerations and political expedience, there were still people willing to die for ideals. They showed that loyalty, honor, and courage weren’t just words—they were principles worth dying for.

Today, if you visit Aizu, you can still see the rebuilt castle, the monuments to the Byakkotai, and the grave of Nakano Takeko. Tourism boards promote the area as a place where you can experience “real samurai culture,” and in a way, they’re right. Because what happened in Aizu in 1868 wasn’t just military history—it was the crystallization of everything the samurai ideal represented.

But perhaps the most moving legacy of the siege is this: in choosing to fight a hopeless battle, in choosing honor over survival, the defenders of Aizu gave Japan something it desperately needed as it rushed toward modernity—a reminder of what it meant to be Japanese. They became living proof that some things are more important than winning, that some principles are worth dying for, and that courage isn’t about the absence of fear—it’s about doing what’s right even when you’re terrified.

The last samurai of Aizu didn’t just die for their lord or their domain. They died for an idea—the idea that there are still people in the world who won’t compromise their souls for convenience, who won’t abandon their principles for comfort, who would rather die as heroes than live as cowards.

And in a world that often seems to have forgotten what honor means, their sacrifice reminds us that some things are eternal. Some things are worth dying for. And sometimes, the most important battles are the ones you know you’re going to lose.

The siege of Aizu ended with defeat, exile, and death. But it also ended with something more powerful than victory—it ended with legend. And legends, unlike battles, are never really lost.

perate months of 1868, when the last true samurai made their stand against impossible odds. This is a story of courage, tragedy, and the price of loyalty—a tale that Japan has never forgotten.
