The Clan's Decline
Loss of Intelligence
The boar clan faces a crisis more tragic than simple population loss—most of their members are slowly falling into stupidity:
- Losing the ability to think and reason
- Becoming more bestial and less divine
- Forgetting ancient wisdom and language
- Succumbing to blind rage and instinct
This deterioration isn't natural aging—it's a spiritual degradation caused by:
- Habitat destruction and forest loss
- Pollution from Iron Town's mining and smelting
- Wounds from human firearms (Ishibiya)
- The psychological trauma of watching their world die
As gods, the boars are tied to the land they protect. When the land suffers, they suffer. When the forest dies, they lose themselves.
Desperation and Final Assault
Recognizing their inevitable extinction, the ancient boar god Okkotononushi decides on a final, suicidal assault against the humans of Tataraba village:
- Gathering the remaining boar clan members
- Leading them in a desperate charge against Iron Town
- Knowing they will likely die
- Choosing violent confrontation over slow degradation
This decision is both tragic and destructive—the boars aren't evil, but their rage makes them dangerous. They cannot see a path to coexistence, only vengeance and annihilation.
Key Clan Members
Nago (Nagonokami)
Nago is a member of the boar clan whose fate sets the entire film in motion:
Attack and Injury
- Nago is shot by an Ishibiya (firearm) from Tataraba village
- The iron bullet lodges in his flesh, causing agonizing pain
- He flees eastward, away from the forest, driven mad by suffering
Denial of Help
- Nago seeks aid from the Shishigami (Forest Spirit / Deer God)
- The Shishigami denies him healing (or perhaps judges him beyond saving)
- This rejection compounds Nago's rage and despair
The Shishigami's refusal is significant—it shows the Forest Spirit operates by rules beyond simple mercy. Life and death, healing and suffering, follow natural law rather than emotional appeals. This ambiguity reflects Princess Mononoke's refusal to present nature as purely benevolent.
Transformation into Tatarigami
Consumed by aggravation, rage, and the iron poison in his body, Nago undergoes a horrific transformation:
- He becomes a Tatarigami (demon god, curse god)
- His body writhes with writhing black tendrils of hatred made manifest
- He loses all reason and divine consciousness
- He becomes a mindless engine of destruction
In this form, Nago travels hundreds of miles eastward, finally reaching Ashitaka's Emishi village.
Attack on the Emishi and Death
- Nago attacks the village in blind fury
- Ashitaka defends his people, firing arrows with deadly precision
- Mortally wounded, Nago lunges at Ashitaka
- Ashitaka delivers a final arrow, slaying the demon
- In death, Nago's hatred transfers to Ashitaka as a curse
The tragedy is complete: Nago suffered at human hands (Tataraba's guns), transformed into a demon, attacked innocent people (the Emishi had nothing to do with his suffering), and cursed a young man who only defended his village. No one wins. Everyone suffers.
Nago's corpse reveals the iron bullet lodged in his flesh—physical evidence of the human conflict spreading across Japan, consuming innocent lives in its wake.
Okkotononushi
Okkotononushi is a very old boar god who takes a leadership role in the clan's final days:
Wisdom and Age
- One of the most ancient boars, possessing great wisdom
- Still retains intelligence and divine consciousness (unlike most of his clan)
- Speaks with gravitas and sorrow about their fate
- Understands the hopelessness of their situation
The Final Assault
Okkotononushi makes a fateful decision:
- He calls together his clan to attack Tataraba village
- Leads them in a desperate charge against the fortified human settlement
- Hopes to destroy Iron Town and stop further forest destruction
- Knows this is likely a suicide mission
The assault reflects both justified rage (the humans are destroying their home) and tragic futility (the boars cannot win against firearms and fortifications).
Deception and Transformation
During the attack:
- Human agents (led by the monk Jigo) deceive Okkotononushi
- They disguise themselves in boar skins, infiltrating the clan
- The deception and violence trigger Okkotononushi's transformation
- He becomes a Tatarigami, just like Nago before him
- His body writhes with demonic hatred, consuming his consciousness
The transformation is heartbreaking—this wise, ancient god, fighting to save his home, loses himself to the same curse that took Nago.
Death by the Shishigami
In his demonic form, Okkotononushi threatens all life around him. The Shishigami appears and:
- Withdraws Okkotononushi's life force
- Grants him death and release from suffering
- Allows his spirit to depart the corrupted body
This mercy-killing underscores the Forest Spirit's role as arbiter of life and death—neither cruel nor sentimental, but maintaining natural balance. Okkotononushi's suffering ends, but his clan's hope dies with him.
Thematic Significance
Cycles of Violence and Hatred
The boar clan embodies the curse of hatred that runs throughout Princess Mononoke:
- Humans destroy forest (for survival, resources, expansion)
- Boar gods suffer (habitat loss, wounds, poison)
- Suffering breeds hatred (transformation into Tatarigami)
- Hatred spreads violence (attacking innocents like the Emishi)
- Violence perpetuates cycle (Ashitaka's curse, continued conflict)
Director Hayao Miyazaki stated the film explores hatred as a plague that consumes all sides. The boars are victims who become perpetrators—their legitimate grievances transform into indiscriminate rage that harms innocents.
No Clear Villains
The boar clan's story illustrates Princess Mononoke's central theme: there are no simple heroes or villains:
- Are the boars justified? Yes—their forest is being destroyed.
- Are they innocent? No—they attack and kill people uninvolved in their suffering (the Emishi).
- Are humans the villains? Partially—but Iron Town provides sanctuary for outcasts and the marginalized.
- Can anyone be blamed? Everyone acts from understandable motives; everyone causes harm.
This moral ambiguity forces viewers to grapple with complex, realistic conflicts rather than simple good-vs-evil narratives.
Environmental Degradation Made Personal
The boar clan's loss of intelligence serves as a powerful metaphor for environmental collapse:
- Ecosystems don't just disappear—they degrade, losing complexity and vitality
- Species don't just go extinct—they decline, losing genetic diversity and adaptive capacity
- Sacred places don't just vanish—they're poisoned, losing the qualities that made them holy
The boars literally lose their minds as their forest dies. This visceral, tragic image makes abstract environmental concerns emotionally concrete.
Gods as Mortal
Unlike some fantasy traditions where gods are immortal and invulnerable, Princess Mononoke's gods can be wounded, poisoned, driven mad, and killed:
- Nago is corrupted by an iron bullet, then slain by Ashitaka's arrows
- Okkotononushi is deceived and transformed
- The Shishigami itself can be beheaded
This mortality makes them vulnerable and relatable—they're not all-powerful protectors but participants in an ecosystem, subject to the same forces of violence and change as any creature.
It also underscores the film's environmental message: even the sacred can be destroyed. There is no divine intervention that will save the forest if humans don't change their ways.
The Price of "Progress"
The boar clan's fate asks uncomfortable questions:
- Is human technological advancement worth the cost of extinct species and destroyed ecosystems?
- Can Iron Town's sanctuary for outcasts justify the death of ancient gods?
- Is there a path to coexistence, or must one side win and the other die?
Princess Mononoke doesn't provide easy answers. The film presents the tragedy without resolving it—by the end, the boar clan is largely extinct, the forest is devastated, and the survivors must rebuild with uncertain hope.
Cultural and Mythological Roots
Japanese Boar Symbolism
In Japanese culture and mythology:
- Wild boars (inoshishi, 猪) are symbols of courage, recklessness, and wild nature
- Associated with mountains and deep forests
- Considered both dangerous (aggressive when threatened) and noble (brave, strong)
- Sometimes viewed as divine messengers or mountain gods in Shinto tradition
Miyazaki draws on these associations while subverting them—his boars are divine, but fallible; courageous, but doomed.
Tatarigami Concept
The Tatarigami (祟り神, "curse god" or "demon god") concept appears in Japanese folklore:
- Spirits or gods transformed by rage, resentment, or suffering
- Bring curses, plagues, and misfortune to those they touch
- Can be appeased through ritual or must be destroyed
- Represent the dark side of the divine—nature's wrath made manifest
Princess Mononoke uses Tatarigami to visualize hatred as a supernatural infection—not metaphorical, but literally spreading through physical contact.
