Oda Nobunaga: The Sites He Built, the Battles He Won, and What Remains Today
Oda Nobunaga came closer than anyone to unifying Japan, then died in one of history's most dramatic betrayals. His castles no longer stand — but the ruins, battlefields, and stone foundations are still there to visit.
If you found Nobunaga through SHŌGUN, the history books, or Assassin's Creed Shadows — this is where to go deeper. Oda Nobunaga (1534–1582) was the warlord who came closer than anyone to unifying Japan, and then died in one of history's most dramatic betrayals. He is counted as the first of Japan's Three Unifiers — ahead of Toyotomi Hideyoshi and Tokugawa Ieyasu — and his campaigns, castles, and battlefield decisions reshaped the country permanently.
None of his castles survive intact, but the ruins of Azuchi, the slope of Okehazama, and the stone foundations at Kiyosu are still there to visit. This page brings together every site guide on Following the Shogun — with access information, 360° panorama photos, and field notes from the ground.

Who Was Oda Nobunaga?
Oda Nobunaga was born in 1534 in Owari Province (modern-day Aichi Prefecture) and died in 1582 at Honnō-ji Temple in Kyoto — betrayed by his own general, Akechi Mitsuhide. In the roughly 25 years between his rise to power and his death, he transformed Japanese warfare, dismantled the Buddhist military institutions that had wielded political power for centuries, and built Azuchi Castle, the first true tenshu (main keep) in Japan's history.
He is counted as the first of Japan's Three Unifiers (Tenka-Sanbu): Nobunaga started the process of national unification, Toyotomi Hideyoshi continued it after Nobunaga's death, and Tokugawa Ieyasu completed it in 1603. His motto, Tenka Fubu ("Rule the Realm by Force"), was stamped on his official documents as a declaration of intent — not a slogan, but a political statement that he intended to centralize Japan under his authority.
His body was never found after the fire at Honnō-ji. The mystery of his death — and whether he truly died that day — has been discussed by historians for four centuries.

The Real History Behind SHŌGUN's Kuroda Nobuhisa
In the FX/Hulu drama SHŌGUN, the shadow ruler whose death sets the entire story in motion is Kuroda Nobuhisa — a fictional character, but one drawn directly from the life and legacy of Oda Nobunaga. Nobuhisa does not appear in the action directly; he exists through portraits, references, and the political vacuum his death created. That structure mirrors Nobunaga's actual historical role: a figure whose absence shaped everything that followed.
The parallels are specific. Kuroda's sudden assassination by a trusted general (Akechi Jinsai in the drama) echoes the Honnō-ji Incident of 1582, when Nobunaga was betrayed by Akechi Mitsuhide. The political scramble that follows — who controls the heir, who inherits the power — reflects the historical aftermath of Nobunaga's death, when Hideyoshi moved swiftly to avenge him and seize the advantage.
Lady Ochiba's position in the drama — heir to a vanished ruler's authority — echoes Yodo-dono (Chacha), who was Nobunaga's niece in real history, not his daughter as the series depicts. That change was made to strengthen her personal stake in the drama's central conflict.
Note: In real history, Lady Ochiba (Yodo-dono / Chacha) was the niece of Oda Nobunaga. The series adjusts this relationship to a father-daughter dynamic to sharpen her political standing in the story.

What Remains of Nobunaga's Japan Today
No castle directly associated with Oda Nobunaga survives in its original form. What visitors find are ruins, archaeological sites, reconstructed keeps, and former sites where the history is carried by the landscape and the stones that remain.
Azuchi Castle (Shiga Prefecture) is the most significant Nobunaga site for visitors. The stone foundations of the main keep, the approach path lined with original stone, and the grave of Oda Nobunaga's father survive on Mt. Azuchi. A museum at the base provides historical context. Access is a short walk from Azuchijō Station on the JR Biwako Line — a day trip from Kyoto or Osaka.
Gifu Castle has a modern reconstruction on the summit of Mt. Kinka, built in 1956. The original castle associated with Nobunaga no longer exists, but the mountain setting and the views over the Nōbi Plain give a strong sense of why this location mattered strategically. Accessible by ropeway from central Gifu, under an hour from Nagoya by train.
Kiyosu Castle (Aichi Prefecture), one of Nobunaga's early bases, has a reconstructed tower built in a relocated position — the original site is now occupied by the Kiyosu City hall area. The reconstruction includes a museum focused on Nobunaga's early career. Reachable by local train from Nagoya in about 20 minutes.
Okehazama Battlefield (Aichi Prefecture) is where Nobunaga defeated the vastly superior forces of Imagawa Yoshimoto in 1560 — the battle that made his reputation. The battlefield area is now divided between two competing memorial sites in neighboring municipalities. Access by bus and train from Nagoya.
Individual guide pages detail the current condition of each site, what is original, what is reconstructed, and what is an estimated former location.
Explore Nobunaga Sites by Prefecture
Each guide below includes access information, historical context, 360° panorama photos where available, and candid notes on what you will actually find on the ground. Sites are grouped by prefecture to make trip planning easier — most can be combined as day trips from Nagoya (Aichi/Gifu) or from Kyoto and Osaka (Shiga/Kyoto).
Aichi Prefecture
Nobunaga's home province. Aichi holds the sites of his early career: Kiyosu Castle (his first major base), Nagoya Castle (where he was born, though the current castle is Tokugawa-era), and Okehazama Battlefield, where the 1560 victory against Imagawa Yoshimoto made his name. All are practical day trips from Nagoya by train.
Gifu Prefecture
After taking Inabayama Castle in 1567, Nobunaga renamed it Gifu — giving both the city and the castle their modern names. Gifu Castle's current keep is a 1956 reconstruction on the summit of Mt. Kinka, but the mountain setting and the views over the Nōbi Plain remain unchanged from Nobunaga's time. Accessible by ropeway from central Gifu, under an hour from Nagoya.
Shiga Prefecture
Shiga holds Nobunaga's most significant and most visited site: the Azuchi Castle ruins on Mt. Azuchi, designated a Special Historic Site. The stone foundations of the main keep, the approach path, and the grave of Nobunaga's father survive on the mountain. Anegawa Battlefield in the north of the prefecture, where Nobunaga defeated the Azai and Asakura clans in 1570, is also covered here. Both sites are reachable by JR Biwako Line from Kyoto or Osaka.
Kyoto
Kyoto is where Nobunaga's story ended. Honnō-ji Temple — the site of his death in 1582 — was relocated and rebuilt after the fire; the current temple stands a short walk from Kyoto's Kawaramachi area. Several other temples and shrines in Kyoto are connected to Nobunaga's campaigns, his political dealings with the Imperial Court, and the aftermath of his death.
Nara Prefecture
Nara Prefecture contains several sites connected to Nobunaga's campaigns in the Kinai region, including locations associated with his conflicts with the Miyoshi clan and the religious institutions of the area. Fewer sites in Nara are directly linked to Nobunaga compared to Aichi or Shiga, but they fill in an important part of his campaigns toward the capital.
How to Plan Your Route
Most Nobunaga-related sites fall into two regional clusters. The first is the Nagoya–Gifu corridor (Aichi and Gifu prefectures): Kiyosu Castle, Komakiyama Castle, Gifu Castle, Okehazama Battlefield, and several smaller sites are all reachable by rail or car from Nagoya, making them practical half-day or full-day trips. The second cluster is the Lake Biwa region (Shiga Prefecture): the Azuchi Castle ruins are best accessed from Kyoto or Osaka via the JR Biwako Line (approximately 30–40 minutes from Kyoto to Azuchijō Station). Anegawa Battlefield in northern Shiga and several Nobunaga-linked sites in Kyoto complete the route. Individual access guides, maps, and travel times are in each child page below.
Nobunaga's Era in Assassin's Creed Shadows
Assassin's Creed Shadows (2025) is set in late Sengoku Japan — Nobunaga's Japan. The game's historical backdrop is the period of his rise to dominance, and several locations in the game correspond to real sites covered on this site: the castle towns, the approaches to Kyoto, and the landscape of the Biwa region.
Nobunaga himself appears in the game as a historical character, giving players a version of the man that draws on his reputation for ruthlessness and military innovation. The real Nobunaga was both of those things — and also a patron of the arts, a trade reformer, and someone who engaged seriously with the Jesuit missionaries who arrived in Japan during his lifetime. The site guides here are built on primary sources and on-the-ground visits, so if you want to cross-reference what the game shows with what the history actually records, these pages are a useful starting point.
Frequently Asked Questions
Oda Nobunaga (1534–1582) was a warlord of Japan's Sengoku period and the first of the country's Three Unifiers. He built Japan's first true castle keep at Azuchi, introduced firearms as a central battlefield tactic, and dismantled the Buddhist military institutions that had held political power for generations. He was betrayed and killed by his general Akechi Mitsuhide in the Honnō-ji Incident of 1582, at age 49.
Yes. Kuroda Nobuhisa is a fictional character in the FX/Hulu drama SHŌGUN, but he is directly modeled on Oda Nobunaga — including his sudden death at the hands of a trusted general, the political vacuum that followed, and the shadow his legacy casts over the surviving characters. The drama does not depict Nobunaga's events directly; instead, it begins after "Kuroda's" death and shows its consequences.
In June 1582, Nobunaga was staying at Honnō-ji Temple in Kyoto with only a small guard when his general Akechi Mitsuhide turned his army against him. Surrounded and with no way to escape, Nobunaga set fire to the temple and died inside — though his body was never recovered from the ruins. Why Mitsuhide betrayed him has never been definitively established, and the mystery has been debated by historians ever since.
None of Nobunaga's castles survive in original form. Azuchi Castle — his greatest project — exists as nationally designated special historic ruins on Mt. Azuchi in Shiga Prefecture: the stone foundations and approach path remain. Gifu Castle has a 1956 reconstruction. Kiyosu Castle has a reconstructed tower in a relocated position. Many associated sites are former locations or archaeological ruins. Each guide page on this site details what physically remains at that specific location.
For visitors with an interest in Sengoku history, yes — though the setting requires some expectation management. There is no standing castle: what you visit are the mountain, the stone foundations, and the approach path. The ruins are designated as a Special Historic Site, and the climb through forested stone terraces to the main keep foundation is genuinely evocative. A museum at the base provides reconstruction models and historical context. Allow 2–3 hours including the climb.
For first-time visitors, Nagoya is the most practical base. From there you can reach Kiyosu Castle (about 20 minutes by local train), Gifu Castle (under an hour), and Okehazama Battlefield as day trips. For Azuchi Castle ruins and Anegawa Battlefield, base yourself in Kyoto or Osaka and take the JR Biwako Line. Access details and travel times are in each guide page.
Most Nobunaga sites are practical day trips. Gifu Castle is reachable from Nagoya in under an hour. Azuchi Castle ruins can be visited as a day trip from Kyoto or Osaka. Kiyosu Castle is about 20 minutes from Nagoya by local train. More remote battlefield sites such as Anegawa may require more planning. Access details and estimated travel times are in each individual guide page.
Tenka Fubu (天下布武) was Nobunaga's personal motto and seal, meaning roughly "Rule the Realm by Military Force." He used it on official documents and equipment as a political statement: that his authority was not merely regional but national in scope, and that he intended to impose it by force if necessary. It was a direct challenge to the existing political order — including the shogunate and the court.
Yes. Nobunaga was among the earliest Japanese commanders to integrate firearms (arquebuses, introduced to Japan by Portuguese traders around 1543) into battlefield tactics at scale. The Battle of Nagashino in 1575, where his forces defeated the Takeda cavalry, is the most famous example. The traditional account of a "three-stage volley" tactic has been questioned by recent scholarship, but the use of concentrated arquebusier fire was real and decisive.
Akechi Mitsuhide, one of Nobunaga's most trusted and capable generals, turned his army against Nobunaga at Honnō-ji in 1582. The motive remains one of Japan's most-debated historical questions. Theories include personal humiliation inflicted by Nobunaga, political ambition, external manipulation by other factions, or ideological disagreement. No single explanation has been confirmed from the historical record, and Mitsuhide himself was killed in battle less than two weeks later — before any account of his reasoning could be established.
Yes. Oda Nobunaga appears as a historical character in Assassin's Creed Shadows (2025). The game is set during the late Sengoku period — the era Nobunaga dominated — and he features in the story in a role consistent with his historical reputation for ruthlessness and military authority. The real history of this period, and the sites associated with Nobunaga, are covered in depth across this site.
Nobunaga's sites are closely linked to Toyotomi Hideyoshi (who continued his campaigns after his death), Tokugawa Ieyasu (his ally and eventual successor to power), Akechi Mitsuhide (who betrayed him), and Maeda Toshiie (a loyal general). Many of the battlefields on this site also cover the forces he fought against — the Asakura, Azai, and Takeda clans. Individual guide pages note which figures are connected to each specific site.
