How much of Team Ninja's Sengoku epic is historically accurate? From the Tiger of Kai to the Warrior Who Never Bled — the truth behind the legends.
Begin the Deep Dive
The word "Sengoku" literally means "Warring States" — 戦国時代. If you know your Chinese history, that name is borrowed directly from China's own Warring States period, the Zhanguo Shidai. Same characters. Same chaos.
It starts with the Onin War in 1467 応仁の乱 — a succession dispute in Kyoto 京都 that spirals into a decade of urban warfare. By the time the fighting stops, central authority in Japan has completely collapsed. The shogun is a figurehead. The old feudal order is shattered. Hundreds of regional warlords — the daimyo 大名 — carve out domains through war, alliance, and betrayal.
This is the world where three men emerge as Japan's "Great Unifiers."
Crushed the old order with gunpowder and ruthless ambition. The central figure of Nioh 2.
Born a commoner, became the most powerful man in Japan. In Nioh 2, he's Tokichiro 藤吉郎.
Outlived everyone else and founded a dynasty lasting 265 years. The heart of Nioh 3.
The entire Nioh series is built on this arc. Nioh 2 covers the Nobunaga and Hideyoshi era. Nioh 1 climaxes at the Battle of Sekigahara 関ヶ原の戦い in 1600. And Nioh 3 shows what happens next — the fragile peace, the succession crisis, and the echoes of war that refuse to die.
Kunimatsu, consumed by dark forces, attacks Edo Castle with yokai. Takechiyo is sent back in time and must earn the right to become shogun through supernatural trials.
Their parents openly favored Kunimatsu (Tadanaga 忠長). Takechiyo was sickly with a stutter. His wet nurse Kasuga no Tsubone 春日局 went over his parents' heads to Ieyasu, who sided with Takechiyo.
The person who saved Takechiyo's future? His wet nurse — Kasuga no Tsubone 春日局. In the game, she appears as Saito Fuku 斎藤福, your Onmyo magic mentor. In real life, she traveled to Ieyasu's retirement residence in Sunpu 駿府 and made the case directly to the old shogun.
The game takes a real succession crisis and turns it into a supernatural epic. The names, the relationships, the stakes — all grounded in history. The yokai are the fiction. The family drama is the truth.
He was called the Tiger of Kai — 甲斐の虎. His rivalry with Uesugi Kenshin 上杉謙信, the Dragon of Echigo 越後の龍, produced five legendary battles at Kawanakajima 川中島. But for the Nioh 3 story, it's his campaign against Tokugawa Ieyasu that matters.
Shingen marched ~30,000 troops south from Kofu 甲府 into Totomi Province 遠江国. His real target was Oda Nobunaga 織田信長.
Against all advice, Ieyasu marched 11,000 men into Shingen's 30,000. The Takeda "fish scale" formation crushed the Tokugawa line. Ieyasu escaped with five men.
Ieyasu ordered castle gates wide open. Fires lit. War drums beating. A total bluff. Hanzo's ninjas raided the camp. Shingen withdrew.
Shingen died months later. The cause is still debated — a sniper, pneumonia, or something else. His death changed everything.
Without Shingen, his son Katsuyori 勝頼 led the Takeda to destruction at Nagashino 長篠 in 1575, where massed arquebus fire annihilated the famous Takeda cavalry. The Tiger of Kai was stopped not by a battlefield defeat, but by his own mortality.
But here's the most human part of Tadakatsu's story — something no game can capture.
Honda Tadakatsu retired to Kuwana Castle 桑名城 and took up woodcarving. One day, while carving, he cut his own hand. It was the first time in his entire life he had ever bled from a blade.
Seeing his own blood, the man who had survived 57 battles took it as an omen. He believed his time had come. Within weeks, at age 63, he willed himself to die.
The warrior who surpassed death itself — brought down not by any enemy, but by a piece of wood and the weight of his own legend.
The nickname "Oni no Hanzo" 鬼の半蔵 — Demon Hanzo — didn't come from sneaking around in shadows. He earned it at the Battle of Mikatagahara for distinguished combat, commanding an Iga unit of 150 men.
Silent, shadowy, supernatural. Master of stealth and assassination. The pop culture archetype of the shinobi.
Nobody called him a "ninja" until the 20th century. The first fiction connecting him to the ninja mythos was a 1958 novel.
His greatest achievement did involve those Iga connections. In 1582, after Akechi Mitsuhide 明智光秀 assassinated Oda Nobunaga at Honno-ji 本能寺, Ieyasu was stranded near Osaka 大坂. Hanzo mobilized 200-300 Iga warriors and escorted Ieyasu through dangerous mountain passes to safety.
This is the Iga Crossing 伊賀越え — arguably the single most consequential "ninja" operation in Japanese history. If Ieyasu had been killed, the Tokugawa Shogunate 徳川幕府 never happens. 265 years of history — erased.
The pop culture ninja — silent, emotionless, deadly — couldn't be further from the real man.
So how does Team Ninja's version stack up against the historical record?
The yokai in Nioh have always worked as metaphors. The chaos of the Sengoku period — the civil war, the betrayal, the destruction — these were Japan's real demons. Nioh 3 takes the literal approach and makes you fight them. But the underlying truth is the same.
There's a reason the Sengoku period is Japan's most popular historical setting. It's the same reason China keeps returning to the Three Kingdoms. These eras have everything — larger-than-life personalities, impossible reversals, questions about power, loyalty, and what it means to build something lasting from destruction.
The Tiger of Kai. The Warrior Who Never Bled. The Demon Who Cried. The Patient Shogun.
These aren't just boss fights and NPC allies. They were real people who shaped one of the most important transitions in Japanese history.
