Otomo Sorin - Chat with ChatGPT (December 14)
Chat with ChatGPT (December 14)
During the Sengoku period, what was the maximum extent of the Otomo clan's territory in Kyushu, and around what year was it?
ChatGPT: The maximum extent of the Otomo clan's territory during the Sengoku period is considered to have been reached in the mid-16th century (specifically the 1550s to the early 1570s), a period when they brought the six major provinces of northern Kyushu under their control.
Specific regions (at their peak)
Under the reign of the clan head Otomo Yoshishige (later Sorin), the Otomo clan greatly expanded their power and seized control of the following regions:
Bungo Province: The home base (present-day Oita Prefecture)
Buzen Province: Eastern part of northern Kyushu
Chikugo Province: Present-day southern Fukuoka Prefecture
Hizen Province: Present-day Saga Prefecture and eastern Nagasaki Prefecture
Higo Province: Present-day Kumamoto Prefecture
Chikuzen Province: Present-day Fukuoka Prefecture
Furthermore, depending on historical documents, it is noted that they may have exerted influence over parts of Hyuga Province (Miyazaki Prefecture) and Iyo Province (eastern Ehime Prefecture), though the reality of their control fluctuated depending on the region and time period.
Thus, the Otomo clan's largest territory was in the form of governing the "six provinces of northern Kyushu (Bungo, Buzen, Chikugo, Chikuzen, Hizen, and Higo)."
Period of peak power
This expansion was most prominent from the late 1550s to the early 1570s, and they unified control over northern Kyushu particularly from the Eiroku era (1558–1569) through the early Tensho era (1570s). Their power declined rapidly after being defeated by the Shimazu clan at the Battle of Mimigawa in 1578.
Estimated area (approximate)
Converting the number of provinces at the time into area, the six provinces alone correspond to the majority of present-day Oita, Fukuoka, Saga, Nagasaki, and Kumamoto prefectures. The total area is on the scale of approximately 30,000 to 40,000 square kilometers based on the current total of those prefectures (although exact 'kokudaka' and map-recorded values vary significantly in Sengoku period documents, it is certain that they widely controlled the northern to central parts of Kyushu Island).
As described above, the control of the six provinces of northern Kyushu from the 1550s to the early 1570s was the Otomo clan's largest territory and the pinnacle of their power as a Sengoku daimyo.
Me: It looks like an immense power, so why did it decline?
ChatGPT: The decline of the Otomo clan was not due to one single decisive cause, but rather the result of multiple structural factors erupting simultaneously. The main causes are summarized as follows.
1. Territorial expansion was not 'direct control'
At its peak, the Otomo territory was not as unified as it appeared.
Much of it was a loose form of control based on the 'submission' of local kokujin (landholders), powerful shugodai (deputy military governors), and vassal classes.
Unlike the clan-based and blood-related unity of the Shimazu, it was a structure that would immediately collapse if interests diverged.
In particular,
Chikuzen and Chikugo,
Hizen and Higo,
had little 'Otomo influence,' and Sorin's control over them was fragile.
2. The transformation of Sorin's political and military path
Otomo Sorin was a capable Sengoku daimyo in his youth, but he changed significantly in his later years.
(1) Inclination toward Christianity
Destruction and confiscation of temple and shrine properties
Denial of Buddhist authority
→ Loss of spiritual support from local lords and the samurai class
More than Sorin's personal faith itself, the loss of his political sense of balance was fatal.
(2) Withdrawal from the military front
He stopped leading campaigns himself, leaving command to his vassals
His 'military prestige' as a Sengoku daimyo declined rapidly
3. Internal division and the loss of capable vassals
Conflict among senior vassals
Death or defection of influential warlords
Collapse of unity among family members and senior retainers
Example:
The deaths of "pillar"-level warlords such as Bekki Akitsura (Tachibana Dosetsu) and Takahashi Shoun
The territory was maintained while they were alive, but it collapsed all at once the moment they were lost.
(4) The Shimazu clan's "extraordinary military rationality"
The Shimazu were the most battle-hardened group in Kyushu at the time.
Practical tactics such as the "Tsurino-buse" (lure and ambush)
Unified combat command between lord and retainer
Extremely high quality of soldiers
This was decisively demonstrated in the 1578 Battle of Mimigawa.
Otomo army: Large in number but lacking control
Shimazu army: Small in number but sophisticated in movement
-> Total defeat
With this single battle,
"The Otomo are no longer strong"
became the reputation that spread throughout all of Kyushu.
(5) It was a regime built on "trust" rather than "fear"
The Otomo clan's rule did not rely on overwhelming military force enforced by fear, but rather on mediation, authority as a prestigious family, and Sorin's personal capability.
The moment that trust crumbled due to Sorin's erratic behavior and military defeats, defections cascaded like an avalanche.
Conclusion
The Otomo clan was
> A regime that 'appeared' powerful, but was actually built upon a very delicate balance
An overextended territory
A governance structure that could not be directly controlled
The transformation of the family head
Internal family division
The existence of a natural enemy in the Shimazu clan
These factors erupted simultaneously, and the regime collapsed all at once following the Battle of Mimigawa.
The decline of the Otomo clan is one of the most prominent examples in the Sengoku period of a 'giant state collapsing overnight'.
Me: In the eastern provinces, Oda Nobunaga protected Christianity and attacked Buddhism, much like Otomo Sorin. Nobunaga's destruction of Buddhist temples and massacres of Buddhist monks continued almost every year. Whether or not this was the cause, rebellions by his own kin and allies followed one after another, and Nobunaga's regime was toppled in 10 years. Is religion an untouchable subject?
ChatGPT: To start with the conclusion, it is not that 'religion itself is untouchable,' but rather that when you destroy the <social integration mechanism> that religion provided, a regime becomes extremely unstable.
Nobunaga and Sorin certainly took similar stances, but it is necessary to distinguish between their differences and commonalities.
① Nobunaga's religious policy was not 'suppression of faith'
First, to clarify the facts, Nobunaga did not view Buddhism in general as an enemy or massacre it.
His main targets of attack were
Religious forces that were armed and possessed their own military, taxation, and judicial powers
Mount Hiei Enryaku-ji (warrior monks)
Ikko-ikki (Hongan-ji forces)
To Nobunaga, they were not religious figures, but a 'state within a state' that infringed upon his sovereignty.
His protection of Christianity was also not based on theological empathy, but was a political card used to relativize the power of temples and shrines.
(2) Even so, it is a fact that he 'destroyed too much'.
However, and this is the core point,
Nobunaga
underestimated the social and psychological functions that religion fulfilled.
The roles played by Buddhist temples:
The spiritual center of local communities
Funerals and ancestor worship
Customary law and dispute mediation
Education and welfare
He
burned,
slaughtered,
and dismantled these.
As a result, while Nobunaga's power could rule through 'fear,' it could not rule through 'conviction'.
(3) The decisive commonality with Sorin
This is where Otomo Sorin and Nobunaga share a commonality.
They destroyed the authority of traditional religion,
but were unable to provide an alternative principle of integration.
Although Sorin destroyed Buddhism and devoted himself to Christianity,
he could not create a new value system to unify his retainers, local lords, and peasants.
Nobunaga also thoroughly destroyed the existing order, but he fell before completing a 'system' that would function automatically after his death.
(4) The reason why Nobunaga's reign looks like a '10-year administration'
The reason the Nobunaga administration seems short-lived is that its foundation of control relied on Nobunaga's personal charisma and fear, and he destroyed too many naturally occurring loyalty mechanisms such as religion, custom, and blood ties.
As a result, his retainers followed Nobunaga as an 'individual'.
They were not following the state.
→ The moment the 'individual' disappeared at Honno-ji,
the administration evaporated at the same time.
(5) The answer to 'Is religion untouchable?'
The answer is clear: the <functions> that religion performs are close to untouchable.
It is not the content of the faith itself.
It is not the gods or the Buddha either.
It is a mechanism that binds people, convinces them, and makes them accept death.
If you are going to destroy this, you must simultaneously provide alternative philosophies, systems, laws, and education.
In the sense that they could not do that, Otomo Sorin collapsed as a local government, and Oda Nobunaga faltered just before founding a nation.
Summary
Both Nobunaga and Sorin,
> did not perish because they meddled with religion.
They prioritized destruction too much before completing the 'meaning of rule' to replace religion.
In this one respect, they are very similar. The reason Toyotomi Hideyoshi and Tokugawa Ieyasu did not completely reject temples and shrines, but instead reorganized them as subjects of management and control, was precisely because they saw through this failure.
Me: Nobunaga first met the missionary Frois in the 12th year of Eiroku. The location was on a bridge over the moat of the Shogun's palace, which was under construction in Nijo, Kyoto. It is said that Nobunaga liked Frois, as the meeting lasted for two hours.
Since the location was on a bridge, many onlookers gathered. Nobunaga, spotting Buddhist monks among them, is said to have shouted in a voice so loud it even surprised Frois, saying:
"I hate those Buddhist monks and want to kill them all, but if I did that, the public would be unsettled, so I leave them alone."
The fact that Nobunaga's hatred of Buddhism was not a 'policy' but something more personal is evident from the fact that it was not inherited by his sons, Nobutada and Nobukatsu. Of course, it was not inherited by Hideyoshi or Ieyasu either.
ChatGPT: Your point is generally valid and hits on an important aspect.
To summarize, it is highly likely that Nobunaga's hostility toward Buddhism was not a 'consistent policy as a national strategy,' but rather contained extremely personal and emotional elements.
1. The significance of the Frois testimony
The account of the first meeting with Frois in the 12th year of Eiroku (1569) is one of the most vivid parts of the 'History of Japan' when considering the image of Nobunaga.
It was not a formal council setting.
There was little need to put on a diplomatic facade.
Words spoken spontaneously in front of a crowd.
The statement made here,
> "I want to kill them all, but the public would be unsettled, so I leave them alone"
shows his true feelings, where rational policy judgment and intense hatred coexisted.
This is not the language of 'religious policy,' but closer to an outburst of Nobunaga's personal emotions.
2. The personal nature of his hatred for Buddhism
Nobunaga's dislike of Buddhism was not a rebuttal of doctrine or opposition as a religious ideology, but closer to a physiological aversion to the hypocrisy of monks, their parasitism on authority, and their armed, privileged status.
The burning of Mount Hiei was also so persistent and emotional that it cannot be explained solely by saying it was 'necessary for the state.'
3. The weight of the fact that it was not inherited by his successors
This point is extremely important.
Toyotomi Hideyoshi
Tokugawa Ieyasu
Both adopted a policy of utilizing, managing, and systematically reorganizing Buddhist forces, and Nobunaga's impulse to destroy Buddhism was not inherited at all.
This means that Nobunaga's hostility toward Buddhism was a product of his individual temperament and personality, which could not be inherited, and was neither a 'system' nor an 'ideology'.
4. Points for revising the image of 'Nobunaga the Rationalist'
Nobunaga is often depicted as a cold-blooded rationalist and a pioneer of modern thinking, but this point clearly needs revision.
Nobunaga was a person who possessed both rational aspects and extremely emotional and impulsive aspects, and his hatred of Buddhism is a typical example of the latter.
Even if he knew as a rational judgment that 'it is more profitable not to kill now,' he did not suppress the emotion itself of 'hating them so much that I want to kill them.'
5. Why did the regime still function?
The Nobunaga regime functioned for a certain period because:
His intense personal charisma
A series of military successes
A situation where destroying the existing order itself was profitable
overlapped, and it was not a reproducible governance model.
That is precisely why, when the individual disappeared at Honno-ji, his religious policies and regime philosophy also vanished.
Conclusion
As En-no-Shin-san says, Nobunaga's hatred of Buddhism was a personal inclination, not a policy.
That is why it was not inherited by his successors or by those who became rulers of the realm.
Nobunaga was not a 'person who redesigned religion as a governing apparatus'.
He was an extremely exceptional ruler who harbored an intense hatred for the very existence of religion.
Because of that exceptionalism, he moved history, but at the same time, because of that same exceptionalism, it did not last long.
Me: Well, if you were asked to draw an image of Otomo Sorin, what kind of picture would you draw? Explain your idea in text.
ChatGPT: If it were me, I would draw "not the 'hero at his peak,' but 'Sorin past his prime, already beginning to collapse'." Below is the composition plan.
Overall Concept
"A Sengoku daimyo losing his balance between faith and power"
Neither heroic nor fanatical.
A portrait that simultaneously exudes intelligence and anxiety, reason and emptiness.
1. Time Setting
Early Tensho period (early 1570s)
Before the Battle of Mimigawa, but the household is already restless
A period when he is becoming devoted to Christianity
2. Posture/Composition
Indoors
Sitting, but his posture is slightly slumped
His back is not fully straight
Indicating that the "tension" of a military commander is being lost
His sword is placed nearby, but his hands are not touching it
Implying that military might is no longer his main focus
3. Facial features and expression
Thin build
Eyes are narrow, with a somewhat unfocused gaze
Eyes that are "looking" at something, but not at reality
The expression is not one of intimidation or confidence, but the fatigue of a person who has understood too much
Not a religious ecstasy, but a "blankness resulting from overthinking"
4. Costume and accessories
A hitatare that is not overly luxurious
Colors are muted dark blue or dark brown
Avoids flashy battle attire
Symbolically:
Holding a small cross in hand
-> However, not gripping it tightly
-> Indicates that faith is both a support and an escape
5. Background
Dim light filtering through shoji screens
It is sunny outside, but the room is full of shadows
A folding screen in the back
-> What is depicted there is not a battlefield, but
-> Abstracted mountains and clouds (distance from reality)
Do not place any Buddhist altar fittings.
However, leave only the "traces of their removal"
(such as unnatural blank spaces on the floor or differences in color).
6. What the painting tells us
This painting tells us the following:
Otomo Sorin was not incompetent,
nor was he a madman.
However,
the speed of "destroying" and "creating replacements" did not align,
and he was the person who realized this imbalance faster than anyone else.
Summary
The image of Sorin to be depicted is:
> Not a portrait of a victor,
nor a portrait of a loser,
but an "intellect standing still amidst a crumbling equilibrium."
I believe this ambiguity is what most accurately visualizes the person known as Otomo Sorin.
Afterword
The "Meisho Genkoroku" (Records of Famous Generals' Words and Deeds), written at the end of the Edo period, contains 192 "famous generals" from the Sengoku to Edo periods. Otomo Sorin is not included among them, although his retainers, Bekki Akitsura (Tachibana Dosetsu), Takahashi Joun, and Tachibana Muneshige, are. Despite Sorin becoming the lord of six provinces in Kyushu, the reason he was not included is unknown. Perhaps in the eyes of the author, Okaya Shigezane, Otomo Sorin appeared as a "misguided general" obsessed with womanizing and the Southern Barbarian religion (Christianity).
