Miyoshi Nagayoshi: Japan's Forgotten Tenkabito[edit]

Tenkabito - 天下人. A term with huge implications. The ruler of the realm. The great unifier of Japan. The one who rescued Japan from the clutches of chaos brought about by the "warring states" period. The concept of Tenkabito has been much altered and misused in latter years to mean the unification of all Japan, but in the mid 1500's, tenka referred not to the entire archipelago but to the five Kinai provinces — Yamashiro, Yamato, Settsu, Kawachi, and Izumi. This was the political and economic heart of Japan with Kyoto (emperor and shogun) and Sakai (commercial and trading hub). Whoever held Kinai effectively “ruled the realm.”

When we hear 'tenkabito' we typically picture the “Three Unifiers” — Oda Nobunaga, Toyotomi Hideyoshi, and Tokugawa Ieyasu. Yet before Oda Nobunaga even set sights on Kyoto, Miyoshi Nagayoshi (1522–1564) had already achieved what his successors would later claim.

~The rise of Miyoshi Nagayoshi (1539-1549)~[edit]

The Miyoshi clan, based at Shouzui Castle in Awa, were vassals of a branch family of the Awa Hosokawa. Their forces played a key role in the Hosokawa Rebellion which saw Hosokawa Harumoto defeat Hosokawa Takakuni to become the new Kanrei (管領) - the Shogun’s deputy, chief administrator and power brokers. However Harumoto was jealous of the power and influence flaunted by the Miyoshi in his regime and schemed with the Ikko-shu monks of Yamashina Honganji to attack and kill Motonaga in 1532.

Following his father's death, Miyoshi Nagayoshi, just 11, swore to avenge his father's murder. Many of the family retainers in Settsu fled from the Miyoshi banner after Motonaga's death and the young Nagayoshi went back to Awa. In 1539, Miyoshi Nagayoshi returned to Settsu and settled into Koshimizu Castle as deputy governor.

Throughout the 1540s, Nagayoshi served under Hosokawa Harumoto while gradually undermining him, capitalizing on Harumoto’s weakness and his reckless lieutenant Kizawa Nagamasa. The shogunate itself was unstable: Ashikaga Yoshiharu abdicated to his young son Yoshiteru and rival Hosokawa factions shifted loyalties. Amid this turmoil, Nagayoshi quietly expanded his influence. He allied with nearby Matsunaga Hisahide at Takiyama Castle (Settsu) (modern day Kobe) and built commercial ties with Sakai. He married into the Yusa clan — an ally and powerful family with maritime roots in Kishū and Settsu. This alliance brought him naval resources, control of coastal trade routes, and further legitimacy among merchant and warrior circles alike.

In 1549, Nagayoshi struck decisively at the Battle of Eguchi (See Eguchi Castle and Enami Castles, defeating Hosokawa Harumoto and his allies. For Nagayoshi, it was the long-awaited vengeance for his father Motonaga’s death seventeen years earlier at Harumoto’s hands. Harumoto fled to Omi with both Ashikaga Yoshiharu and Yoshiteru, leaving Kyoto in Miyoshi’s hands. Nagayoshi and Hosokawa Ujitsuna entered the capital, but Ujitsuna, though nominally kanrei, was firmly under Nagayoshi’s control. With the Hosokawa regime and the shogunate effectively collapsed, Nagayoshi emerged as the new master of the realm.

~Securing The capitol (1550-1558)~[edit]

Harumoto and the Ashikaga did not simply abandon the capital. Through a series of counterattacks, they sought to rally allies in Ōmi to help reclaim Kyoto. In 1550, Yoshiteru constructed Nakao Castle and reinforced Shogunyama Castle on the ridges overlooking eastern Kyoto. Nagayoshi responded swiftly, winning small-scale engagements and sending troops into Ōtsu and Sakamoto to threaten Yoshiteru’s rear. Facing defeat, Yoshiteru set fire to Nakao Castle and fled to Omi (Katada) — the clash remembered as the Battle of Nakao Castle.

In 1551, Miyoshi Nagayoshi survived two assassination attempts, almost certainly orchestrated by Ashikaga Yoshiteru. (Could they have involved Koka Castles, through his connection to the Rokkaku? The Kōka had a long history of supporting the Ashikaga.) Weeks later, Shōkokuji Temple became the focal point of a new assault on the capital by pro-Hosokawa forces, but Nagayoshi prevailed again, thanks to his key generals Matsunaga Hisahide and Matsunaga Nagayori, and 40,000 troops summoned from across neighboring provinces under his influence.

Despite the peace, tensions flared again in 1553 when Ashikaga loyalists rose in rebellion at Akutagawasan Castle. Nagayoshi left the capital and laid siege to the mountain fortress. While Nagayoshi was engaged there, Yoshiteru and Harumoto tried once more to retake Kyoto. They fortified Higashiyama Ryōzen Castle above the Higashiyama district and dispatched troops to Funaokayama Castle in northern Kyoto. Nagayoshi countered by returning with 25,000 reinforcements. The Ryōzen fortress was quickly burned down by the Imamura (who built nearby Amidagamine Castle) with only minimal losses to the Miyoshi side. Yoshiteru and Harumoto once again fled to Ōmi — this time remaining quiet for nearly five years.

After taking Akutagawasan Castle, Nagayoshi made it his first great stronghold — fitting for a tenkabito. Nagayoshi placed his trusted general Matsunaga Hisahide in charge of Koshimizu Castle. Akutagawasan Castle gave Miyoshi a powerful strategic anchor directly on the Tōkaidō highway, controlling both trade and military movements between the port city of Sakai and the political capital. This was the start of his “split capitol” concept. Nagaoyoshi is well known for keeping The State and Commerce separate with military and politics centered in Kyoto and commerce in Sakai.

Nagayoshi presided over the capital not only as a general but as its de facto governor. He fortified and scaled up Saiin Castle to the west of the palace astride the main artery leading to the palace forcing traffic around the castle as both a show of power and a way to control access. The castle was the only large scale properly fortified castle in the capital with a large boro style building (early tenshu).

In 1558, the Ashikaga attempted one last comeback from Shogunyama Castle and Nyoigatake Castle, sparking the brief Battle of Kitashirakawa. The defeat convinced Rokkaku Yoshikata that backing the Ashikaga was a futile cause. Acting as mediator, he brokered a settlement between Yoshiteru and Nagayoshi, finally acknowledging Miyoshi dominance over the capital. Yoshiteru returned to Kyoto, but the real power was Nagayoshi.

Miyoshi in Tanba
A Prelude to Mitsuhide

From his base at Akutagawasan Castle, Miyoshi Nagayoshi launched a series of expeditions into Tanba Province. These campaigns　were aimed at suppressing local clans who might ally with the Hosokawa or Ashikaga and threaten Kyoto from the northwest. Nagayoshi’s trusted captains — including Matsunaga Hisahide and his brother Nagayori and Naitō Sōsho pushing north into Tanba and Tango — extended Miyoshi influence deep into the mountains. Though not a full-scale conquest, these campaigns foreshadow Oda's Tanba Campaigns with Akechi Mitsuhide a decade later, the subject of another upcoming feature.

~Nagayoshi’s Zenith and legacy (1559–1561)~[edit]

After taking Akutagawasan Castle in 1553, Miyoshi Nagayoshi established his authority from this strategic mountaintop castle. Situated above the Tōkaidō highway in northern Settsu, the castle gave him control over movements between Kyoto, Sakai, and the wider Kinai region. Many of his top retainers had palaces on the mountain around the castle. From here, he enforced order in the capital and directed further campaigns into Yamato and Tanba. It served not only as his command center but as the headquarters of a de facto shogunate.

In 1559, Nagayoshi appointed his trusted general Matsunaga Hisahide as shugo-dai (governor) of Yamato Province — a move that expanded Miyoshi control into the south and laid the foundation for Hisahide’s own political ambitions. Hisahide established his personal stronghold at Shigisan Castle, a mountain fortress overlooking both the Nara basin to the east and the plain extending to Osaka Bay in the west.

In 1560, Nagayoshi was elevated to the high court title of 相伴衆（Shōban-shū）“Companion to the Shogun.” Though an honorific title, it placed him among the most powerful non-royal figures in the Kyoto court.

At the same time, instability within Kawachi Province forced Nagayoshi to intervene directly. He seized both Takaya Castle at the foot of the mountain and Iimori Castle at its summit. He then transferred Akutagawasan Castle to his heir, Miyoshi Yoshioki, and moved his own base of operations to Iimori Castle.

This relocation marked a new phase in his rule. Iimori Castle sits at the northern end of the mountain ridge dividing present-day Osaka from Nara. It is directly across the valley from Akutagawasan Castle, giving the Miyoshi full logistical control over the corridor. Every strategic movement between the capital, the ports and the southern and eastern provinces passed through Miyoshi-controlled territory.

The similarities between these two castles reflect Nagayoshi’s governance philosophy. He extensively renovated both, expanding their network of baileys and living quarters, unusually large for mountaintop castles of the time. Neither developed a castle town. These were not commercial or residential hubs but symbols of power and centers of military-administrative command. Sakai was the center of commerce.

By 1560, Nagayoshi’s power had reached its zenith. The phrase「飯盛で決まる」— “Decisions are made at Iimori” was commonly used, a testament to his unchallenged dominance in Kyoto politics. He directly governed the five core Kinai provinces: Yamashiro, Yamato, Settsu, Izumi, and Kawachi — Japan’s rich heartland of politics, culture and commerce.

Through relatives, retainers, and allies, he also held sway over: Awaji, Awa, Sanuki, Harima, Iyo, and Tanba — while also maintaining active influence in Ōmi, Iga, Kii, and Wakasa. Altogether, his sphere of influence was larger, more powerful, and more prosperous than any of his contemporaries. This was the true peak of the Miyoshi regime and far more than he strictly needed to achieve the status of the first 'tenkabito', yet he never claimed the title of shogun (unlike some that followed). He was satisfied to be the real power of the land and to control the court through Ashikaga Yoshiteru.

~Trajedy and Betrayal (1561-1564)~[edit]

The undoing of the Miyoshi regime began with personal tragedies. In 1561, his brother Sogō Kazumasa died suddenly of illness. In 1562, another brother — Miyoshi Saneyasu (Jikkyū) — was killed during a small uprising by the Hatakeyama. Then in 1563, his son and heir Yoshioki, based at Akutagawasan Castle, also died. Nagayoshi was forced to adopt his nephew Miyoshi Yoshitsugu as heir. That same year and into 1564, former rivals turned allies — Hosokawa Ujitsuna and Hosokawa Harumoto — also passed away, leaving a vacuum in the upper echelons of Nagayoshi’s political system.

Matsunaga Hisahide
Master Castle Builder

Despite his ruthless and manipulative nature, Matsunaga Hisahide was a visionary in castle construction. His fortresses were innovative, strategically placed, and often grand. Click the castles for more details.

Shigisan Castle (信貴山城) A vast mountaintop fortress behind Chōgosonshi-ji Temple, overlooking both the Nara Basin (Yamato) and Kawachi. It became Hisahide’s primary stronghold.
Tamon Castle (多聞城) Strategically positioned above the Nara plains. Featured Japan’s first known tenshu (main keep) and a luxurious palace. Its design is said to have inspired Nobunaga’s Azuchi Castle.
Kaseyama Castle (鹿背山城) A more intricate Yamato fortress with an unusually high number of uneno tatebori (parallel cut moats). More sophisticated than typical regional mounts — a hidden gem.
Ryūōzan Castle (龍王山城) His other mountaintop redoubt near present-day Yamatokōriyama. To be visited — but its scale and complexity are well attested in Edo-period records.

In 1564, acting on allegations from Matsunaga Hisahide and Yoshitsugu, Nagayoshi executed his brother Ataka Fuyuyasu for suspected treason. He later regretted the decision after learning he had likely been manipulated. This quick succession of deaths not only shattered the foundation of Nagayoshi’s power and stability, but devastated Nagayoshi himself. He quickly weakened and died on July 4, 1564

The death of Nagayoshi threw the realm into chaos. Yoshitsugu, still a teenager (just 15 years old), was left nominally in charge, but real power fell to the so-called Miyoshi Three, Nagayasu, Masayasu, and Tomomichi. These senior retainers lacked both Nagayoshi’s charisma and political acumen. They ruled by intimidation and force, undermining Nagayoshi’s carefully built regime.

Matsunaga Hisahide, once Nagayoshi’s most trusted general, used the instability to further his own ambitions, acting independently from his strongholds across Yamato — including Shigisan, Tamon, Kaseyama, and Ryūōzan Castles. In 1565, Matsunaga and the Miyoshi Three attacked the shogun in Kyto and assassinated Shogun Ashikaga Yoshiteru. His son, Yoshiaki, fled the capital. The alliance between Matsunaga and the Miyoshi soon soured, sparking conflict across Yamato. In 1566, Matsunaga’s forces (in)famously burned down Tōdaiji during one of these battles.

By then, Nagayoshi’s order was gone. The capital region was in disarray, and the timing was perfect for Oda Nobunaga to step in. Matsunaga superficially submitted to Oda, but he was still scheming. In 1571, Nobunaga attacked Shigisan Castle, and Matsunaga and his son perished in a final act of defiance. It’s another tragic end. Matsunaga had stood by Nagayoshi’s side for over two decades. After witnessing the brilliance of Nagayoshi and the fragility of rule, he should have learned how to wield real power. But, in the end, the legacy of Miyoshi Nagayoshi was undone not by his enemies, but by the men who once stood closest to him.

It’s all the more tragic when we recall how the story began. Nagoyoshi’s Father, Motonaga, was betrayed by the Hosokawa he had long served. Nagayoshi rose to power seeking to avenge the injustice that had crushed his family. He succeeded. But in the end, he was brought down by the same forces. The son who avenged his father’s betrayal was, in time, betrayed by his own.

~Observations~[edit]

While visiting the castles around the greater Kyoto area, one figure keeps appearing from Osaka to Nara to Kyoto: Miyoshi Nagayoshi. My image of Miyoshi was just another of the local warlords who Nobunaga eventually crushed in his detiny to unify the country. He often appeared as a thorn in the side of both the emperor and shogun alike. Some even called him a "shadow shogun" or a "puppet master".

But looking closer, this isn’t just another regional warlord crushed in the march toward unification.

The story of Miyoshi Nagayoshi is a reminder that the narratives of the “Three Unifiers” have blinded us to other points of view. For over a decade, Nagayoshi was the first tenkabito. Had he lived longer, it might have been his ambition — not Nobunaga’s — that reshaped Japan.

Miyoshi dismantled the Hosokawa network, sidelined the shogun, and dominated the 13 provinces of the Kinai–Setouchi corridor. He laid the groundwork for Nobunaga to step in and seize the empty reins of the tenkabito with minimal resistance — much of the hard work had already been done by Nagayoshi.

As I look at the end of the story, the suspicious succession of deaths among Nagayoshi’s closest allies and even Nagaoyshi himself, it all raises unsettling questions. Did Matsunaga Hisahide quietly orchestrate their removal? Poison them? Manipulate them into conflict? The timing is hard to ignore.

It’s all the more tragic when we recall how the story began — with the death of his father, Miyoshi Motonaga, betrayed by the Hosokawa he had long served. Nagayoshi rose to power seeking to avenge the injustice that had crushed his family. He succeeded. But in the end, he was brought down by the same forces. The son who avenged his father’s betrayal was, in time, betrayed by his own.**

I started this journey with the notion that Miyoshi Nagayoshi simply does not receive the recognition that he deserves from history. history was colored by the chroniclers that followed the three great unifiers, but the incompetence of the Miyoshi Three, and the opportunism of Matsunaga Hisahide, ultimately tarnished the legacy of the man who once ruled the capital, the court, and the economics of the nation — without ever claiming the title of shogun. The story of Miyoshi Nagayoshi is a Shakespearean tragedy: a ruler at the peak of his power, undone not by enemies on the battlefield, but by personal loss and betrayal from within.

Hey NHK! Where’s the Miyoshi Nagayoshi Taiga Drama? This story writes itself! Do we really need another glorification of the same three unifiers? What's next year’s story? More Toyotomi? Oh! How original…

~Field Notes~[edit]

This article is not meant as an exhaustive survey of Miyoshi related castles. It is a narrative that ties together some of the many related sites already on [Jcastle.info](http://jcastle.info/) and provides background for future explorations. I tried to connect as many as possible into the narrative but had to leave some out (Kizu castle, Shizuhara Castle) This also only lightly touches upon Matsunaga Hisahide. I’ve skipped over many details (and castles!) that could be drawn into an intriguing profile for him too.

Someone, please stop me! This is the third big article feature I’ve done this year and I outlined at least 4 more…. they take too much time and effort… with yamajiro season right around the corner, I’ll need to refocus my castle efforts. Maybe the autumn visits will help fill out one of my other outlines…

not to blow my own horn or anything here, but I think I’ve raised the bar on mapping once again. Using GeoJSON for the old provincial borders with shading, adding castle markers and text references really sets this site apart. Believe it or not I’ve always had a thing for maps. I took a cartography class in college and wanted to be a cartographer or map librarian once but then thought that everything to be mapped had been mapped and there would be no future in the profession! There was no way to see the revolution that Google maps, laser mapping, and all sorts of digital cartography tools (GIS) would bring to the world.
