Inu-Oh
犬王
A 2022 anime film directed by Masaaki Yuasa, following the friendship between the extraordinary noh performer Inu-Oh and a blind biwa player in Muromachi-period Japan. The recovery of sunken Heike swords at Dan-no-ura drives the supernatural narrative.
Description
Overview
Inu-Oh is a 2022 anime film directed by Masaaki Yuasa, based on Hideo Furukawa's novel about the 14th-century noh performer Inu-Oh and his friendship with a blind biwa player named Tomona. Set in early Muromachi-period Kyoto, it blends historical fiction with supernatural elements and bold rock-musical set pieces to tell the story of two outcasts who create revolutionary art together.
The Swords of Dan-no-ura
At the heart of the story lies the retrieval of Heike clan treasures — including swords — from the seabed of the Dan-no-ura strait where the Taira were defeated in 1185. Tomona's father dies attempting to recover a cursed Heike sword, and Tomona himself loses his sight as part of the price. This motif places Japanese swords at the intersection of history, spirituality, and curse — embodying the belief that a sword retains the soul of its owner beyond death.
Noh Theater and Sword Culture
Noh drama, codified by Zeami in the Muromachi period, draws heavily on warrior themes — the Dan-no-ura battle, armor, and tachi feature prominently in classic pieces like "Funa-Benkei" and "Tomoe." The stylized sword movements of noh are a living archive of warrior aesthetics, making the film a meditation on how sword culture is preserved in performing arts.
Reception
Selected for the Annecy International Animated Film Festival in 2022, Inu-Oh was praised globally for its visual audacity and thematic depth. It stands as one of the most original treatments of Japanese sword mythology in contemporary animation.
Real Swords Featured
The Lost Kusanagi (Sword of the Imperial Regalia)
When the Taira clan fell at Dan-no-ura in 1185, one of the Three Imperial Treasures — the Kusanagi no Tsurugi (Grass-Cutting Sword) — was lost to the sea with the infant Emperor Antoku. The mirror and jewel were recovered; the sword was not. This 'sword sleeping on the ocean floor' legend is the direct prototype for the cursed Heike blade motif in Inu-Oh and represents the apex of Japanese sword mythology.
Ko-Bizen and Ko-Aoe Tachi (Late-Heian Blades)
The swords that would have sunk with the Heike at Dan-no-ura belonged to the oldest surviving schools of Japanese swordmaking — Ko-Bizen (Old Bizen, Okayama Prefecture) and Ko-Aoe (Old Aoe). Blades from these schools, dating to the late Heian and early Kamakura periods, are characterized by elegant shallow curvature and fine wood-grain jitetsu. Several Heike-associated pieces are now designated National Treasures.
