The world of "Nansō Satomi Hakkenden" by Kyokutei Bakin

Description

Murasame-maru is the legendary sword that appears in Nansō Satomi Hakkenden (南総里見八犬伝, "The Eight Dog Warriors of the Satomi Clan of Nansō"), the monumental serialized novel by Kyokutei Bakin (1767–1848), written over twenty-eight years from 1814 to 1842. The work spans ninety-eight volumes across one hundred and six books — a scale unprecedented in Japanese literature. Unlike the other blades in this collection, Murasame-maru is not a physical sword: it is a literary creation, born in the imagination of Japan's greatest Edo-period novelist. Yet its place in Japanese cultural memory is secure. No survey of famous Japanese swords would be complete without it.

The story centers on eight warriors — the Hakkenden, or "Eight Dog Warriors" — each of whom carries one of eight sacred beads inscribed with the Confucian virtues: humanity, righteousness, propriety, wisdom, loyalty, faithfulness, filial piety, and brotherly love. These warriors are destined to gather and restore the honor of the Satomi clan of Awa Province (present-day Chiba Prefecture), a real historical clan that Bakin used as his canvas for an elaborate tale of karma, fate, supernatural combat, and moral virtue. Murasame-maru is the blade that enters battle in their hands.

Its most famous property is this: after it cuts, when the blade is returned to its scabbard, water flows down it — a shower of rain, murasame, cleansing the steel of all blood. The name itself means 'scattered rain' or 'passing shower.' The sword does not carry blood. The sword does not carry stain. This detail — small, extraordinary — captures something deep in the Japanese imagination about blades and purity. A sword that kills without being defiled. A weapon that cleanses itself. It is a literary rendering of the idea that the sword in its highest form partakes of the divine.

Bakin was writing in an era of rigid censorship and social constraint, and his novel — ostensibly a historical adventure set in the Muromachi and Sengoku periods — was also a vehicle for moral and Buddhist philosophy. Murasame-maru is an artifact of that world: a sword that does not merely cut, but restores.

Légendes et récits

The legend at the heart of Nansō Satomi Hakkenden begins with a lord's careless jest. Satomi Yoshizane, cornered in his castle by enemies, joked that any man who could bring him the enemy commander's head could have his daughter in marriage. His dog, Yatsufusa — a great beast who understood human speech — took the words literally. He brought the head. He claimed the princess. And so the lord's daughter Fusehime went to live with a dog in the mountains of Awa, where she died — but in dying, the sacred prayer beads she wore shattered and eight glowing spheres flew to the corners of the world. Each bead bore one of the eight Confucian virtues: jin, gi, rei, chi, chu, shin, ko, tei — humanity, righteousness, propriety, wisdom, loyalty, faithfulness, filial piety, and fraternal love. Each bead entered the womb of a woman and was born into a warrior. These were the Hakkenden, the Eight Dog Warriors, and Murasame-maru was the sword they carried into destiny. The sword's name means 'scattered rain,' or more poetically, 'a passing shower.' In classical Japanese poetry, murasame is a word for the brief, sudden rain of autumn — present one moment, gone the next, leaving everything glistening and clean. This is precisely what the sword does. After a kill, when it is slid back into its scabbard, water runs down the blade. Not blood. Water. Rain. The sword refuses to carry stain. Kyokutei Bakin — who wrote the entire ninety-eight volume work over twenty-eight years, and who dictated the final portions to his daughter-in-law Michi after he went blind — created in Murasame-maru a sword that embodies his entire moral vision. A blade of perfect virtue does not remain stained. A life of perfect virtue does not accumulate regret. The rain falls, the water runs clean, and the sword returns to rest.
