Nobunaga Oda If you look into, you will find that the castles are changing one after another (the Sengoku daimyos at that time did not change their homes very much).
In this article, Nobunaga's strategy and territory development is relocated to the castle I will look at it from the perspective of.
Nobunaga has been
Nakoya Castle ⇒ Kiyosu Castle ⇒ Komaki Yamashiro ⇒ Gifu Castle ⇒ Azuchi Castle
I changed the castle according to the situation at that time.
Nobunaga can think like this because his father, Oda Nobuhide Probably because of the existence of. Nobuhide also started Shobata Castle Was a residence, but 1532 Nakoya Castle And then Kotojo I moved to and made it a residence.
I can say that it was a strategy because I was looking at his father's back.
Nakono Castle (Nagoya Castle)
Nakono Castle Until 1532 Imagawa Ujitoyo It was located in Naka-ku, Nagoya City, Aichi Prefecture, as the residence of the castle.
1532 Nobuhide Oda who got Nagono Handed over Nakono Castle to Nobunaga, who was still young.
Nobuhide built a castle in Kowatari and made it his residence in preparation for the attack on Mikawa.
At this time, he became the owner of Nakono Castle at a young age, but Nobunaga will manage the castle on his own initiative after his genpuku in 1536.
His father, Nobuhide, was Mino's Saito Dosan around this time. And Kiyoyasu Matsudaira of Mikawa ( Ieyasu's grandfather) was alternating with each other. However, when Kiyoyasu Matsudaira of Mikawa passed away, Tokai's best Yumitori-shiki Imagawa Yoshimoto It will be confronted with Mr. Imagawa and will start to be pushed.
Nobuhide, who is a good warrior, has a bad match with two major Japanese military commanders. Will be done. As a proof of that, Firstborn Nobunaga and Dosan's daughter Nohime Will be exchanged.
The Oda clan's reign and the death of Dosan Saito
In 1551, Nobunaga died suddenly, and Nobunaga succeeded the family, but the Oda family had a dispute over the family.
Owari at that time was Kiyosu Castle Lord Nobutomo Oda Was in control. Nobunaga's Oda clan was only his vassal, but his father, Nobuhide, ruled the western part of Owari.
After the death of his father Nobuhide, it was Nobutomo Oda, the guardian of Kiyosu Castle, who disagreed with Nobunaga's inheritance. Nobutomo his younger brother Nobuyuki Oda Conflict with Nobunaga in support of. Here, Nobunaga is Oda Nobumitsu of Moriyama Castle Ruins. We will wipe out the anti-Nobunaga faction with the cooperation of.
Nobunaga overwhelms Kiyosu here Kiyosu Castle Lord It will be.
This Kiyosu is prospering as the center of Owari Province, which is the center of transportation where the Kamakura Kaido and Ise Kaido meet. Therefore, Nagono will be entrusted to his uncle Nobumitsu, and his own castle will be moved to Kiyosu Castle.
Nobunaga, who became the head of the Oda clan in both name and reality, was a veteran of the Oda clan who questioned his skill. They plot a coup to abolish Nobunaga and support his younger brother's deeds.
On the Nobunaga side, Mori Yoshinari, Sakuma Morishige, Sakuma Nobumori They are on their side and the two companies are in conflict.
Meanwhile, 1556 Yoshitatsu, the son of Dosan Saito of Mino, rebels and Dosan is defeated It will be. Taking advantage of Dosan's death, Nobunaga raises troops to Nobunaga in August of the same year, but suffers a defeat.
Nobunaga surrounded Nobunaga in the castle, but forgave them through the mediation of his mother.
Shibata Katsuie and other senior vassals who were impressed by this will pledge allegiance thereafter.
In 1557, Nobunaga attempted a rebellion again, but due to the secret notice of Katsuie Shibata, who was in communication with Nobunaga, he took measures to kill Nobunaga.
Around this time, Oda Isemori's Oda Nobuyoshi , the ruler of Owari Kamishogun I'm having a bad relationship with.
According to one theory, Saito Yoshitatsu's strategy It is also said to be. So Nobunaga decides to avenge Nobunaga. At that time, his cousin Inuyama Castle owner Nobukiyo Oda Succeed in destroying with the help of.
Thus 1559 In fact, you will be in control of Owari.
After that, as you all know,
1560 Battle of Okehazama And defeated Yoshimoto Imagawa, the best archer in the Tokai region, and Nobunaga Oda's name became known throughout Japan.
1562 Kiyosu Alliance with Tokugawa By using Tokugawa as a shield for Imagawa and Takeda, it became possible to capture Mino and Joraku without worrying about his patronage.
From here Nobunaga Mino capture Get started for.
Kiyosu Castle-Komakiyama Castle
Nobunaga holds the real power of Owari, but he is unique with the sphere of influence of his cousin Oda Nobukiyo centered on Inuyama Castle in the north. was doing.
Speaking of Nobukiyo, he is a meritorious person who cooperated in attacking Nobukiyo Oda of the Oda Isemori family.
The territory of Oda Nobukiyo's former Oda Isemori family was divided between Nobunaga and Nobukiyo, but Nobukiyo was dissatisfied with that division. The head of the Saito family in Mino at the time when he learned of the dissatisfaction Yoshitatsu Makes full use of the strategy to turn over. The strategy will be effective after Yoshitatsu's death It will be.
Probably Yoshitatsu Saito is before Okehazama It is said that he was working hard on the strategy. He may have already been in the process of defeating Nobuyoshi Oda.
1556 Yoshitatsu, the son who defeated Dosan Saito, puts a choke on the Oda clan as if he had never been married. The result may have been the battle for the Oda clan. Yoshitatsu seems to have been a military commander who was as good at wisdom as his father Dosan.
Opportunity to attack Mino Province
Nobunaga, who has put together a series of quarrels, now sets a goal for Mino.
This is where Nobunaga comes to a turning point.
1561 Troublesome Yoshitatsu Saito dies suddenly I did.
Nobunaga attacks Mino with the arrival of a chance, but he is suffering a hard defeat due to the success of Takenaka Hanbei and others. Meanwhile, Oda Nobukiyo turns over to the Saito family. If this happens, it will no longer be Mino.
When the northern part of Owari belongs to the Saito family, we have to do something about it in order to capture Mino. Inuyama Castle, the residence of Nobukiyo, is going to be attacked, but Inuyama Castle is a castle that cannot be easily dropped.
This Inuyama Castle is a Yamashiro built on a hill about 88 meters high along the Kiso River. is. In fact, Nobunaga's army is attacking Yamashiro I have never done it. To do that, he had to train his army.
Construction of Komakiyama Castle
There are no mountains in this Kiyosu.
So Nobunaga thought about building a castle on Mt. Komaki. He can be trained and he can be a stepping stone to capture Inuyama Castle, so did he say two birds with one stone? In addition, it was also a spectacular place where you can see Inabayama Castle.
And in 1563, he built a castle on Mt. Komaki. It is the first castle built by Nobunaga.
Previously, Komakiyama Castle was evaluated as a bridge to Gifu Castle, but a castle town was newly established by archaeological excavation in recent years, and the main enclosure is covered with stone walls, and its structure is similar to Azuchi Castle. It turned out that it was a castle.
I often hear that this Komaki mountain castle was built in preparation for the capture of Inaba mountain castle in Mino. However, considering the situation at the time when the castle was built and the location of the castle, Komakiyama Castle is the base for capturing Inuyama Castle . It is more natural to see.
As a result, Mt. Inaba fell four years after the construction of Mt. Komaki, but perhaps Nobunaga was moving to the castle in anticipation of a long-term battle.
If Takenaka Hanbei and his colleagues had not taken over Inabayama Castle in 1564, the capture of Inabayama Castle might have been a long way off.
Nobunaga after the construction of Mt. Komaki will capture the branch castle in order to break the branch castle network of Inuyama castle. It is said that this was mainly a strategy by strategy rather than the use of force.
Inuyama Castle is only surrounded in isolation in this way, but 1564 Inabayama Castle hijacking case at this timing Will occur. Nobunaga immediately negotiated with Takenaka Hanbei, the principal criminal of the takeover, to surrender Inabayama Castle, but it broke down, and Hanbei returned the castle to Tatsuoki Saito in just six months.
This incident reveals the internal division of the Saito family. From here, Nobunaga's angry tactics will succeed in drawing in Mino Triumvirate and Takenaka Hanbei.
Then, he won the fierce siege battle of Mino and advanced soldiers to 1567 Inabayama . It will be.
From here, it will be Gifu Castle-Azuchi Castle, but since the story has become long, I will carry it over to the next time.
