What it is

The Momiji Legend centers on a kijo, or female demon, known as Momiji. Her story involves a conflict with the warrior Taira no Koremochi. This narrative is deeply rooted in the geography of Nagano Prefecture. Sites across the region claim connections to her life and death. The tale exists in many versions, ranging from historical chronicles to theatrical scripts. It portrays a complex figure who shifts between villain and victim depending on the telling.

Where it comes from

Scholars trace the legend's prominence to traditional performing arts. The Noh play Momijigari likely originated in the Muromachi period. Kanze Nobumitsu may have created the specific plot involving Momiji. Some researchers believe he invented the character rather than adapting local myths. Other traditions mention earlier demons on Mount Togakushi. These include a nine-headed creature sealed in a cave. They also reference a demon slain by Minamoto no Mitsunaka. These older stories provided a backdrop for the later Momiji narrative.

How it is done

The core event describes a battle between Momiji and Taira no Koremochi. In most accounts, Koremochi receives a divine sword after praying at Bessho Onsen. He uses this weapon to defeat the demoness. Some versions suggest he used deception to approach her. The conflict ends with Momiji's death. Local folklore often marks the site of the fight with named rocks and caves. These landmarks serve as physical reminders of the supernatural struggle.

Tools and materials

The legend features several symbolic objects. A divine sword called the Gōma no Reiken is central to the victory. Maple leaves appear in ritual contexts. They are offered to appease Momiji's spirit during ceremonies. Votive plaques depict the battle scenes. Memorials and stupas mark locations associated with her residence. These items anchor the myth in tangible places within the landscape.
