Yagyō-san (夜行さん) can be translated as "Mr. Night Traveler," an ominous figure known for roaming during the darkest hours.
Illustrated folktale
In the depths of winter, when the snowflakes fell gently on the mountain roads, a lone traveler named Kaito ventured out to tend to his family's farm. His mother had fallen ill, and he was determined to bring her medicine from the village at the foot of the mountain.
As night began to fall, Kaito donned his warmest cloak and set off once more into the darkness. The snow crunched beneath his feet as he walked, the only sound in the stillness. He had heard stories of a fearsome rider who roamed these roads under the cover of night, but he paid them no mind – what danger could there be on such a clear and cold evening?
As he climbed higher into the mountains, the trees grew taller and closer together, casting long shadows across the snow. Kaito quickened his pace, his breath misting in the chill air. Suddenly, a gust of wind swept past him, extinguishing the flame of his lantern and plunging him into darkness.
He fumbled for a match, but before he could light it again, a faint whinny echoed through the trees – a sound like no horse Kaito had ever heard. It was low and mournful, yet seemed to carry an otherworldly weight. He froze, his heart pounding in his chest.
As the whinny grew louder, a figure emerged from the darkness. A rider sat atop a headless steed, its coat a dull gray that blended with the shadows. Kaito could not see the rider's face – it seemed to be hidden behind a veil of mist, or perhaps no veil at all.
The wind picked up again, and this time Kaito felt a chill run down his spine. The silence was oppressive, as if the very forest itself was holding its breath in anticipation of something terrible. He tried to speak, but his voice caught in his throat.
The rider drew closer, its presence filling the clearing with an aura of foreboding. Kaito stumbled backward, tripping over his own feet and falling hard onto the snow. As he struggled to rise, the rider vanished into thin air, leaving behind only the faint scent of smoke and a single hoof print in the snow.
Kaito stumbled back down the mountain, not stopping until he was within sight of his family's farm. He told them of what had happened – the faceless rider and the headless steed – but they looked at him with concern rather than fear. "The Yagyō-san is an old story," his mother said gently. "We shouldn't travel those roads alone, especially not at night."
Kaito nodded, though he couldn't shake the feeling that the Yagyō-san still lingered in the darkness, watching him even now. From that day on, he avoided those mountain roads at all costs, and whispered stories of the faceless rider to anyone who would listen – a warning to stay close to home after nightfall, lest they attract the attention of the Yagyō-san.
