Jitsuroku Nana: The Missing Blade
Original Story A Story of the Otokodate of Yedo from A.B. Mitford's Tales of Old Japan
Afterword & Commentary by Justin Hagen

At this time there lived in the province of Yamato a certain Daimyo, called Honda Dainaiki, who one day, when surrounded by several of his retainers, produced a sword, and bade them look at it and say from what smith 's workshop the blade had come.
“I think this must be a Masamune blade," said one Fuwa Banzayemon
“No,” said Nagoya Sanza, after examining the weapon attentively, “this certainly is a Muramasa.”
A third Samurai, named Takagi Umanojo, pronounced it to be the work of Shidzu Kanenji; and as they could not agree, but each maintained his opinion, their lord sent for a famous connoisseur to decide the point; and the sword proved, as Sanza had said, to be a genuine Muramasa. Sanza was delighted at the verdict; but the other two went home rather crestfallen. Umanojo, although he had been worsted in the argument, bore no malice nor ill-will in his heart; but Banzayemon, who was a vain-glorious personage, puffed up with the idea of his own importance, conceived a spite against Sanza, and watched for an opportunity to put him to shame.
At last, one day Banzayemon, eager to be revenged upon Sanza, went to the Prince, and said, “Your lordship ought to see Sanza fence; his swordsmanship is beyond all praise. I know that I am no match for him; still, if it will please your lordship, I will try a bout with him,” and the Prince, who was a mere stripling, and thought it would be rare sport, immediately sent for Sanza and desired he would fence with Banzayemon
So the two went out into the garden, and stood up facing each other, armed with wooden swords. Now Banzayemon was proud of his skill, and thought he had no equal in fencing; so he expected to gain an easy victory over Sanza, and promised himself the luxury of giving his adversary a beating that should fully make up for the mortification which he had felt in the matter of the dispute about the sword. It happened, however, that he had undervalued the skill of Sanza, who, when he saw that his adversary was attacking him savagely and in good earnest, by a rapid blow struck Banzayemon so sharply on the wrist that he dropped the sword, and, before he could pick it up again, delivered a second cut on the shoulder, which sent him rolling over in the dust. All the officers present, seeing this, praised Sanza 's skill, and Banzayemon, utterly stricken with shame, ran away home and hid himself.
After this affair Sanza rose high in the favor of his lord; and Banzayemon, who was more than ever jealous of him, feigned sickness, and stayed at home devising schemes for Sanza's ruin.
Now it happened that the Prince, wishing to have the Muramasa blade mounted, sent for Sanza and entrusted it to his care, ordering him to employ the most cunning work men in the manufacture of the scabbard-hilt and ornaments; and Sanza, having received the blade, took it home, and put it carefully away.
When Banzayemon heard of this, he was overjoyed; for he saw that his opportunity for revenge had come. He determined, if possible, to kill Sanza, but at any rate to steal the sword which had been committed to his care by the Prince, knowing full well that if Sanza lost the sword he and his family would be ruined. Being a single man, without wife or child, he sold his furniture, and, turning all his available property into money, made ready to fly the country.
When his preparations were concluded, he went in the middle of the night to Sanza's house and tried to get in by stealth; but the doors and shutters were all carefully bolted from the inside, and there was no hole by which he could effect an entrance. All was still, however, and the people of the house were evidently fast asleep; so he climbed up to the second story, and, having contrived to unfasten a window, made his way in. With soft, cat-like footsteps he crept downstairs, and, looking into one of the rooms, saw Sanza and his wife sleeping on the mats, with their little son Kosanza, a boy of thirteen, curled up in his quilt between them .
The light in the night-lamp was at its last flicker, but, peering through the gloom, he could just see the Prince's famous Muramasa sword lying on a sword-rack in the raised part of the room; so he crawled stealthily along until he could reach it, and stuck it in his girdle. Then, drawing near to Sanza, he bestrode his sleeping body, and, brandishing the sword, made a thrust at his throat; but in his excitement his hand shook, so that he missed his aim, and only scratched Sanza, who, waking with a start and trying to jump up, felt himself held down by a man standing over him.
Stretching out his hands, he would have wrestled with his enemy; when Banzayemon, leaping back,kicked over the night-lamp, and throwing open the shutters, dashed into the garden. Snatching up his sword, Sanza rushed out after him; and his wife, having lit a lantern and armed herself with a halberd, went out, with her son Kosanza, who carried a drawn dirk, to help her husband. Then Banzayemon,who was hiding in the shadow of a large pine-tree, seeing the lantern and dreading detection, seized a stone and hurled it at the light, and, chancing to strike it, put it out, and then scram bling over the fence unseen, fled into the darkness.
When Sanza had searched all over the garden in vain, he returned to his room and examined his wound, which proving very slight, he began to look about to see whether the thief had carried off anything; but when his eye fell upon the place where the Muramasa sword had lain, he saw that it was gone. He hunted everywhere, but it was not to be found. The precious blade with which his Prince had entrusted him had been stolen, and the blame would fall heavily upon him. Filled with grief and shame at the loss, Sanza and his wife and child remained in great anxiety until the morning broke, when he reported the matter to one of the Prince's councilors, and waited in seclusion until he should receive his lord 's commands.
It soon became known that Banzayemon, who had fled the province,was the thief; and the councilors made their report accordingly to the Prince, who, although he expressed his detestation of the mean action of Banzayemon, could not absolve Sanza from bla
