This story is a retelling of a tale first recorded in writing in the early 12th century. It is also connected to my blog post about Fujiwara no Yasumasa, who served as governor of Tango Province for four years during the Heian period.
The Flute in the Moonlight
In the tenth month, when autumn had nearly surrendered to winter, the nights around Kyoto had begun to acquire a sharpness that entered through even the finest layers of silk. The moon was bright that night, pale and almost severe, and its light spread over the open moor of Ichiharano until the withered grasses seemed to have been covered with silver. The tall susuki bowed and rose again in the cold wind, their dry stems whispering against one another in endless waves. Beyond them, the road lay empty beneath the moon, disappearing into the darkness between the occasional silhouettes of trees.
Along this lonely road walked Fujiwara no Yasumasa.
He was entirely alone. His hakama had been gathered and tucked up slightly to make walking easier, and above them he wore the many layers appropriate to a man of the court: fine silk robes beneath a hunting garment, with the outer folds falling softly around his body as he walked. Even in the wilderness there remained in his appearance something unmistakably refined. The moon caught the edges of the silk and revealed subdued colors beneath the darkness, while the heavier hunting robe gave warmth against the autumn cold. It was clothing of considerable value, the sort of clothing that would have drawn the eye of any thief who understood the ways of the capital.
Yet Yasumasa seemed entirely unconcerned with it.
In his hands he carried a ryūteki flute, and as he walked he raised it to his lips and began to play. The first note was so delicate that it seemed almost to have been produced by the wind itself. Then another followed, and another, until the melody moved steadily across the moor. The sound had the haunting quality of the old court flute, at once clear and distant, its notes seeming to rise from the lonely road and mingle with the rustling susuki. There was no audience for Yasumasa's music and no purpose beyond the pleasure of playing. He walked beneath the moon and played simply because the night was beautiful.
But he was not alone.
Among the silver grasses, a man was following him.

There was no audience for Yasumasa's music and no purpose beyond the pleasure of playing. He walked beneath the moon and played simply because the night was beautiful.
But he was not alone.
Among the silver grasses, a man was following him.
His name was Hakamadare, a notorious bandit and a man of considerable ability. He was not one of those common thieves who depended upon carelessness and surprise alone. He possessed great physical strength and a hunter's patience, and he had learned to move through darkness almost without sound. He could judge a man's wealth from his clothing at a glance, and as soon as he saw the layers of fine silk beneath Yasumasa's hunting garment, he understood what an opportunity had presented itself.
Hakamadare had not come into the wilderness that night for sport. Winter was approaching, and he needed clothing. The nobleman ahead of him was apparently alone, without a guard or companion, and dressed in garments worth considerably more than anything Hakamadare could hope to obtain honestly. He lowered himself among the grasses and began to follow, confident that sooner or later the opportunity would present itself.
At first he kept a considerable distance between them. When Yasumasa walked beneath the shadow of a tree, Hakamadare moved forward. When the moon emerged unobstructed and illuminated the road and the surrounding grass, he stopped and waited. He knew how to stalk a man without being seen, and there was nothing about his movements that suggested haste. In his mind the encounter was already decided. The courtier would continue walking, unaware of the danger behind him, and at the proper moment Hakamadare would strike, take the fine garments, and disappear into the night.
Yet as the distance between them gradually diminished, an uneasiness began to trouble him.
It was not anything Yasumasa did. Indeed, it was precisely what he did not do. The man never glanced behind him. He did not look anxiously toward the darkness on either side of the road, nor did he quicken his pace. He showed no sign that he had noticed the faint sounds behind him. Most strangely of all, he continued to play the flute with the same calm concentration, as though there were nothing in the world worth fearing.
Hakamadare understood fear very well. He had made his living by recognizing it in other men. A frightened traveler became careless. A man who suspected danger looked over his shoulder. Someone uncertain of what was happening hesitated for the briefest instant, and that instant was enough. Every man possessed such openings. Every man had some weakness through which another could enter.
But this man seemed to possess none.
There was no suki.
The realization unsettled Hakamadare more than he wished to admit. Yasumasa's manner suggested not bravado but something much deeper: a mind so completely composed that there was simply no room within it for the presence of fear. His attention remained upon the music, upon the road beneath his feet, and upon whatever quiet thought accompanied the melody. The bandit could not see into his mind, yet he had the strange impression that nothing outside it could disturb him.
Hakamadare continued to follow.
The moon climbed higher. The cold grew sharper, and the tips of the grasses shone with frost. Yet the flute's voice remained warm and strangely intimate, carrying across the empty moor with a sound that seemed almost impossible in such a desolate place. At times the melody appeared to come from far away, as though another musician were playing somewhere beyond the hills; at other times it seemed so close that Hakamadare felt as though the sound were passing directly through him.
He stopped without intending to.
Yasumasa continued onward.
The music moved farther away, and Hakamadare suddenly felt an unreasonable urge to follow it. He stepped forward again. The grasses brushed against his clothing. He moved more quickly now, no longer entirely certain whether he was stalking the nobleman or simply being drawn after him.
He came closer.
The distance between them narrowed until Hakamadare could clearly see the folds of Yasumasa's robes moving with each step. He could hear the quiet sound of his feet upon the road. He could see the flute raised to his lips, and he could hear the controlled breath with which each note was produced.
The bandit reached instinctively toward his weapon.
For a moment the old confidence returned.
He would attack now.
He gathered himself and stepped forward.
The dry grass crackled beneath his foot.
The flute stopped.
The silence that followed seemed far greater than the silence that had existed before the music began.

Yasumasa turned.
There was no alarm in his face.
No sudden movement.
No hand reaching for a weapon.
He merely looked back at the man standing in the moonlight.
Hakamadare froze.
The two men regarded one another across the narrow road. The moon illuminated Yasumasa's face with a pale, almost otherworldly clarity, and in that moment Hakamadare understood something that he had not understood while following him: Yasumasa had known.
He had known that someone was behind him.
Perhaps he had known from the beginning.
Yet he had continued walking and playing as though the knowledge were of no consequence whatsoever.
Yasumasa spoke in a calm voice.
"Who are you?"
The question contained neither anger nor fear.
Hakamadare, whose courage had never deserted him in the presence of armed men, found that he could not lie.
"I am Hakamadare," he answered.
The name carried its own reputation. Yet Yasumasa showed no surprise. He simply regarded the bandit for a moment, as though considering what should be done.
Then he said, "Come with me."
He turned and resumed walking.
Hakamadare remained where he was.
For an instant he did not understand.
Then, almost against his own will, he followed.
The intention with which he had begun the pursuit had vanished. He no longer thought of striking Yasumasa. He no longer looked at the fine garments with the eyes of a thief. Something in the man's composure had overturned the entire balance between them. Hakamadare had approached as a hunter, but now he followed like a man who had suddenly discovered himself in the presence of something beyond his understanding.
Yasumasa began playing again.
The melody returned as naturally as though nothing had happened. His footsteps remained steady, and the sound of the flute once more drifted across the moonlit moor. Behind him walked Hakamadare, silent and subdued.
They continued toward Kyoto.
Gradually the wilderness began to give way to signs of habitation. The darkness was no longer completely empty. Here was the faint outline of a wall, there the roof of a distant residence. The road became more familiar, and the sense of desolation slowly diminished. Yet Yasumasa did not change his pace, his hakama still gathered slightly above his feet, his flute resting in his hands whenever he was not playing.
Hakamadare followed him all the way.
At last they reached Yasumasa's residence.
The gate opened, and Yasumasa passed within.
Hakamadare stopped outside.
For the first time since the beginning of the night, he seemed uncertain what to do. He had followed the nobleman this far without resistance, yet now he stood before the entrance to a great courtier's estate, still wearing the apprehension of a thief who had expected to steal and instead found himself standing openly at his victim's gate.
Yasumasa turned and looked at him.
"Come inside."
Hakamadare obeyed.
The residence was quiet. Behind the walls and shutters lay the refined world of the capital: rooms separated by screens and curtains, polished floors, folded garments, incense lingering faintly in the air. The warmth of the household was a startling contrast to the frozen moor from which they had come.
Yasumasa disappeared for a short while.
There was no alarm in his face.
No sudden movement.
No hand reaching for a weapon.
He merely looked back at the man standing in the moonlight.

The warmth of the household was a startling contrast to the frozen moor from which they had come.
Yasumasa disappeared for a short while.
When he returned, he was carrying a fine set of robes.
He held them out to Hakamadare.
"Take these."
The bandit stared at the garments.
They were finer than anything he had expected to obtain that night. The silk was soft beneath his fingers, and the layers had been carefully arranged for the coming cold. Hakamadare accepted them with both hands and bowed deeply.
Yasumasa did not reproach him.
He did not demand an explanation for the attempted robbery, nor did he call for guards. There was no triumph in his manner, though he had defeated the bandit completely. To Yasumasa, the matter seemed already finished.
"If you have need of clothing," he said gently, "there is no need to take it from a stranger upon the road."
Hakamadare remained bowed.
Yasumasa continued, his voice quiet and dignified.
"Do not place yourself in danger through such acts."
There was no threat in the words. They were spoken almost as advice from one man to another.
Hakamadare raised his head.
He had followed Yasumasa into the night intending to rob him. He had believed that strength, cunning, and courage were sufficient to overcome any solitary traveler. Yet the man before him had defeated him without anger, without violence, and almost without acknowledging that a contest had taken place.
Hakamadare bowed once more.
"Yes, my lord."
Yasumasa inclined his head.
"Go safely."
And with that, he turned and went inside.
The door closed behind him.
Hakamadare remained alone beneath the moon, the fine robes resting heavily in his arms. For some time he stood without moving. Beyond the walls of the residence, the wind continued to pass through the autumn grasses, carrying with it the faint scent of the cold earth and the last traces of the night.
He looked back toward Ichiharano.
The moor lay pale beneath the moon, and for a moment he could almost hear the flute again: that clear, haunting voice moving through the susuki, untouched by fear or malice.
He had gone out into the night as a hunter.
He had returned as a man who had been given what he intended to steal.
And the thing that had stopped him was neither sword nor strength.
It was the serene presence of a man who had walked alone through the darkness, playing his flute beneath the autumn moon, with no opening in his heart through which fear could enter.
He held them out to Hakamadare.
"Take these."

Suki and Fudōshin
At the heart of this story is suki (隙), meaning an opening, gap, or vulnerability. In a confrontation, suki can be a physical weakness, but it can also arise in the mind through fear, hesitation, or distraction.
Hakamadare is waiting for such an opening, but Yasumasa gives him none. His mind remains completely calm and undisturbed. This can be understood through the later concept of fudōshin (不動心), or an “immovable mind”: remaining composed even in the face of danger.
Yasumasa's greatest defense is therefore not physical strength, but the absence of a suki. With nothing to exploit, Hakamadare's confidence gradually gives way to awe.
The story offers a fascinating glimpse of how Fujiwara no Yasumasa was remembered: not only as a man of courage, but as a cultured and remarkably self-possessed aristocrat.
