Etymology and Meaning of the Name
鬼 (ki or oni) refers to demons or ghosts, but in the broader context of Japanese culture, this word can be interpreted as enigmatic beings known as yōkai - creatures that lie somewhere between pure evil and joyful malice, often possessing both terrifying and comical traits.
Together, 百鬼夜行, Hyakki Yagyō is more than just the sum of its parts – it's an invitation to a world where the boundary between what is real and what is supernatural is momentarily blurred. This name not only describes the physical phenomenon of the yōkai parade but also serves as a metaphor for the unfathomable enigma of the Japanese night.


Right behind him, we can observe the tanuki, mischievously deceptive, capable of metamorphosing into everyday objects just to stir up trouble in the lives of simple people. Nearby, glides the Kappa, a water yōkai with a turtle's body and a plate filled with magical water on its head, always ready for pranks and mischief. In the crowd, we can also spot the terrifying Tengu, bird demons with long noses, eagerly waiting to entangle the careless in their intrigues.


Mentions of Hyakki Yagyō in Ancient Texts and Accounts
The origins of Hyakki Yagyō stretch deep into ancient Japanese history, with the first mentions appearing as early as the Heian period (794-1185), when literature and art began to explore the rich world of beliefs in ghosts and yōkai. Texts such as "Konjaku Monogatarishū" not only recounted encounters with supernatural beings but also began to shape conceptions of the night parades of demons. These early stories laid the foundation for the further development of the Hyakki Yagyō motif, transforming it over time into more organized and complex presentations.
The Evolution of the Concept Through the Ages: Cultural Influences and Changes in Perception
As time passed and successive historical periods of Japan arrived: Muromachi and Edo, the concept of Hyakki Yagyō evolved, enriched with new elements and reflecting changing beliefs and social values. In the Muromachi period, emakimono (scroll paintings) depicting Hyakki Yagyō became popular, showing an incredible variety of yōkai in dynamic, often humorous scenes. These visual interpretations contributed to the further dissemination and establishment of Hyakki Yagyō in Japanese culture.
In the Edo period, fascination with yōkai and Hyakki Yagyō reached a new level, exemplified by numerous ukiyo-e (woodblock prints) depicting these phenomena. Popular culture of this period, including kabuki theater and literature, often drew from Hyakki Yagyō motifs, transforming them into an important element of entertainment and art.

Other important events that contributed to the evolution and popularity of Hyakki Yagyō include the development of printing and ukiyo-e, which enabled the wider distribution and availability of images depicting these nocturnal parades. Additionally, in the Meiji period and later, Western influences and the modernization of Japan opened new avenues for the interpretation and depiction of yōkai, resulting in their presence in new media forms, such as manga and anime.
Today, Hyakki Yagyō continues to evolve, combining traditional motifs with modern interpretations, which testifies to the enduring fascination and significance of these supernatural parades in Japanese culture and art. This phenomenon, reflecting human fears, desires, and imagination, remains incredibly vibrant, dynamic, and inspiring for successive generations of creators and audiences.
"Gazu Hyakki Yagyō" – How the Parade of Demons Was Seen in the Edo Period
Toriyama Sekien, born in 1712, was a Japanese ukiyo-e artist, Buddhist monk, and art teacher, who became known as one of the first illustrators to document the rich world of yōkai - Japanese ghosts, demons, and other supernatural beings. His work "Gazu Hyakki Yagyō" (Illustrated Night Parade of One Hundred Demons), first published in 1776, marked a breakthrough in the depiction of yōkai in Japanese culture. Sekien, using his skills and knowledge of folklore, created a series of prints that not only illuminated the mysterious world of yōkai but also gave it a new artistic dimension.

In "Gazu Hyakki Yagyō," one can find a wide range of yōkai, from well-known ones such as tanuki (mischievous animal resembling a raccoon) and kappa (water demon with a turtle's body), to lesser-known and more enigmatic beings, such as Noppera-bō (faceless ghost). Sekien often depicts yōkai interacting with the human world, introducing humorous elements, but also sometimes terrifying ones. His works are characterized by a subtle combination of realism and fantasy, making the viewer feel that the depicted scenes could happen just around the corner.

Literature

While citing this work, it is important to emphasize that although "Tsurezuregusa" contains reflections on life, human nature, and aesthetics, and is not a work focused on yōkai or Hyakki Yagyō, within the broad spectrum of topics covered by Kenkō, there are many references to Japanese beliefs and folklore.
