The Dragon Lady of Seta Bridge: A Tale of Courage and Myth
Japan is a land where the boundary between history and mythology often blurs, nowhere more so than along the shores of Lake Biwa in Shiga Prefecture. Spanning the Seta River, the Seta no Karahashi (Seta Bridge) is not merely a historic crossing; it is the stage for one of Japan’s most thrilling yokai legends. This is the story of the Dragon Lady, a giant centipede, and the fearless samurai known as Tawara Toda.
Origins of the Legend
The Seta Bridge has long been a location of immense strategic importance. An old proverb claims, “He who controls the Seta Bridge controls the world,” highlighting its role as a gateway to Kyoto during the warring periods of Japanese history. However, the folklore surrounding the bridge dates back to the Heian period (794–1185).
The protagonist of this tale is Fujiwara no Hidesato, a historical military commander often referred to by his nickname, Tawara Toda. While Hidesato is a real historical figure credited with suppressing the rebellion of Taira no Masakado in 940 AD, his exploits at Seta Bridge have elevated him from a mere mortal to a mythical hero. The legend appears in various classical texts, blending the ancient worship of water deities (Ryujin) with the samurai ethos of bravery.
The Legend of the Dragon Lady
The story begins one crisp autumn evening. Hidesato set out to cross the Seta Bridge but stopped in his tracks upon seeing a massive obstacle blocking his path. A giant serpent, spanning the entire width of the bridge, lay coiled and heaving. While other travelers fled in terror or took long detours to avoid the beast, Hidesato was undeterred.
Without hesitation, the samurai stepped onto the bridge. Ignoring the creature’s menacing hiss, he calmly walked over the serpent’s back, treating the monster as if it were nothing more than a fallen log. He did not look back until a voice called out to him.
The serpent had vanished. In its place stood a beautiful woman—the Dragon Lady (sometimes depicted as the Dragon King himself or his daughter). She bowed deeply to the samurai. “I have lived beneath this bridge for two thousand years,” she said. “I have watched many men pass, but you are the first brave enough to step over me without fear. I have a desperate favor to ask of you.”
The Battle of Mount Mikami
The Dragon Lady explained that her family was being tormented by a giant centipede (mukade) that lived on Mount Mikami, a conical mountain visible from the bridge. Each night, the centipede would descend to the lake to feast on her kin. She begged Hidesato to kill the beast.
That night, Hidesato waited on the bridge with his bow and arrows. As darkness fell, two great lights like burning torches appeared on the mountain. As they drew closer, the sound of a thousand legs scratching against rock filled the air. The giant centipede, glowing with malevolent energy, descended.
Hidesato fired his first arrow. It struck the beast but bounced off its armored shell. He fired a second arrow, but it too failed to pierce the monster’s hide. With only one arrow remaining, the samurai remembered an old superstition that human saliva could poison centipedes. He spat on the tip of his final arrow, drew his bow with all his might, and released the shot.
The arrow pierced the centipede’s brain, shattering the light in its eyes. The beast crumbled and vanished, saving the Dragon family.
The Rewards
In gratitude, the Dragon Lady took Hidesato to the Dragon Palace beneath the lake. She presented him with legendary gifts: a bag of rice that never emptied, a roll of silk that never ran out, and a magnificent bronze bell. The bell was later donated to Mii-dera Temple, where it remains a cultural artifact today.
Legacy in Modern Culture
The tale of the Dragon Lady and the Centipede remains a vibrant part of Otsu City’s cultural identity. Mount Mikami is still affectionately nicknamed “Mount Centipede” (Mukade-yama) by locals. The legend is frequently retold in Noh and Kabuki theater, serving as a classic example of bravery and the symbiotic relationship between humans and nature spirits.
Culturally, the “centipede” is often interpreted by historians as a metaphor for metal mining clans (who dug into mountains like insects) that may have been in conflict with the water-reliant agricultural communities represented by the Dragon Lady. Today, the story is featured in anime, manga, and video games, often depicting Tawara Toda as a monster-slaying hero.
