Iyo Provinceいよ

This version follows accounts from Iyo, portraying it as a monstrous bird lurking in mountain bamboo thickets. It resembles a chicken with a striking red comb, and in the dark only the comb and the fire it exhales are visible. Its expelled fire is a will-o’-the-wisp without heat that does not ignite objects, said to flicker suddenly along night roads and village borders, leaving a strong memory of beating wings. Nocturnal in habit, it reacts sharply to signs of doors opening or moving lights such as torches, and retreats into the thicket at once. Reports of harming people are scarce, with encounters mostly limited to startling passersby, and villages regarded it as an ambiguous sign of the mountain’s presence—neither auspicious nor ill-omened. Early modern sources also note views likening it to a fire-eating bird and names derived from its wingbeat, blending natural-history notes with tales of the uncanny. In folk belief it is placed among boundary spirits marking the divide between mountain and settlement, a gentle anomaly linked to both ghost-light lore and bird-yokai traditions.

The image of Inugami Gyobu should be understood through the lens of how the Matsuyama tanuki tales were reshaped by kodan storytelling. Across Shikoku, dense beliefs in tanuki and transformation legends spread, and in Matsuyama both “guardian” and “trickster” aspects were told of beings dwelling at the boundary between the castle town and the wilds. The title Gyobu signals a bond with the castle, emphasizing a guardian role, while kodan added favored conflicts—such as inviolable pacts and ambushes during internal clan strife—producing varied plotlines. In every variant, the rock shelters and caves of Mt. Kuma form the final stage, where sealing or pacification brings closure. The appearance of Ino Budayu also became standard, linking in a known monster-slaying tale from other sources and lending a higher authority of supernatural judgment to the Matsuyama tanuki narrative. His spiritual power and many retainers match regional views of a tanuki chieftain leading a band, serving as a framework to explain wonders at annual castle-town events and at passes or shrine precincts. Though today’s lore bears kodan embellishments, at its core remains the figure of a tanuki lord guarding the liminal zone between castle and mountain.

Accounts of the False Locomotive cluster around the era when the alien sounds and sights of steam engines entered rural life, understood through beliefs in beastly transformations and mimicry. Across regions the plot is similar: at night a whistle and pounding wheels approach from ahead, even lights are seen, but everything vanishes just before impact. Soon after, a dead tanuki or badger is found and given memorial rites. Folklorists place it alongside beings like Azukiarai and Sand-Throwers, extending the idea that uncanny noises are the work of animals. Rumors spread not only by word of mouth but also via newspapers, producing uniform distribution and content. Even when tied to specific locales or temples, the core remains threefold: the match of sound and phantasm, and the tangible animal corpse. It declined as modern transport expanded, yet survives in trackside ghost tales.
