What is an Oni? Origins of the Japanese Demon

In Japanese mythology, Oni (鬼) are supernatural creatures belonging to the vast family of yokai. The term literally means "ogre" or "demon" in Japanese.

Physical Characteristics of the Oni

The Oni is distinguished by several characteristic traits: one or two horns on the skull, skin often red, blue, or green, prominent fangs, an imposing and muscular stature, and sharp claws. It traditionally wears a tiger-skin loincloth and wields a kanabō (iron club).

Historical Evolution of the Oni

Originally, the concept of Oni came from China where these creatures were invisible spirits. With the introduction of Buddhism to Japan (6th century), Oni became guardians of the Buddhist hells, tasked with punishing the souls of sinners. Over the centuries, their image evolved to become more nuanced.

Meaning and Symbolism of the Oni Mask

The Oni mask carries an ambivalent meaning, oscillating between protection and terror.

Symbol of Protection

Paradoxically, despite its frightening appearance, the Oni mask is considered a powerful protective talisman. Onigawara (decorative Oni-shaped roof tiles) have adorned the roofs of Japanese temples and homes for centuries to ward off evil spirits and disasters.

Colors and Their Meanings

Each Oni mask color carries particular symbolism:

Red (Aka Oni): represents passion, anger, and desire. This is the most common color.

Blue/Green (Ao Oni): symbolizes illness, negative energy, or emotional coldness.

Black (Kuro Oni): embodies absolute evil, suspicion, and malevolence.

Yellow/Gold: associated with greed and self-centeredness.

The Oni Mask in Japanese Culture

The Setsubun Festival

Every year in early February, Japan celebrates Setsubun (節分), the bean-throwing festival. During this celebration, a family member wears an Oni mask while others throw soybeans at them, shouting "Oni wa soto! Fuku wa uchi!" (Demons out! Fortune in!). This ritual symbolizes the expulsion of evil spirits and welcoming good fortune for the new year.

Noh and Kabuki Theater

In traditional Japanese theater, the Oni mask appears in numerous plays to represent demonic characters or supernatural forces. Artisans create these masks with meticulous attention to detail, each expression designed to evoke a specific emotion depending on the viewing angle.

Famous Oni in Japanese Legends

Shuten-dōji: The King of Oni

Shuten-dōji is considered the most powerful of all Oni. According to legend, this red-haired giant terrorized Kyoto from his lair on Mount Ōe, kidnapping and devouring noble young women. He was finally defeated by the hero Minamoto no Yorimitsu and his four faithful companions using poisoned sake.

Ibaraki-dōji

Lieutenant to Shuten-dōji, Ibaraki-dōji is famous for the Rashōmon Gate incident. The warrior Watanabe no Tsuna cut off his arm during a fight. The Oni later returned disguised as an old woman to retrieve his limb.

Difference Between Oni Mask and Hannya Mask

A common confusion exists between Oni and Hannya masks. Here are the essential distinctions:

The Oni is a male demon, a supernatural creature from its origin, with a wide and massive face.

The Hannya represents a human woman transformed into a demon by jealousy and betrayal. Her face is more tapered, with thin horns and an expression mixing rage and sorrow.
