In the sacred heartland of the Japanese sword, one craftsman is breathing new life into the blades of a legendary age.
Hirotugu Manzoku — working under the swordsmith name Hirotugu — was born in 1969 and operates his forge in Osafune, Setouchi City, Okayama Prefecture, a place revered throughout history as the spiritual home of Japanese swordmaking. Under the tutelage of master swordsmith Aoki Moriye, he began his apprenticeship in 1998, earned official recognition from the Agency for Cultural Affairs in 2003, and subsequently established his independence. He honed his early craft within the storied forge of the Bizen Osafune Japanese Sword Museum before opening his own studio, where he continues to pursue his art with tireless dedication.
At the heart of Manzoku's work lies the great tradition of Bizen Osafune — a school of swordmaking that flourished during the golden age of the Kamakura period and produced some of the finest blades in Japanese history. His recreation of swords in the style of the Fukuoka Ichimonji school stands as a crowning achievement: magnificent tachi featuring the bold inokubi kissaki — a powerful, boar-necked tip — adorned with a vivid and lustrous chōji hamon, capturing the very spirit of the master smiths who came before him.
Among his most celebrated works is Seikaiha ("Blue Ocean Waves") — a remarkable blade forged from steel salvaged from the wreck of the Imperial Japanese Battleship Mutsu. A fusion of solemn history and consummate craftsmanship, this sword stands as a testament to what is possible when a swordsmith of rare ability confronts the weight of the past.
Manzoku's signature style is immediately recognizable to the trained eye. His blades are distinguished by a vigorous gunome-choji hamon — a bold, undulating clove-blossom tempering pattern alive with nie activity — and by the elusive, ghostly phenomenon known as utsuri: a faint, luminous reflection that drifts across the surface of the steel like mist on still water. Once thought to be a secret lost to time, utsuri is a hallmark of the ancient Bizen tradition, and its presence in a modern blade is a mark of exceptional mastery.
Beyond the long sword, Manzoku also crafts exquisite small knives (kozuka and utility blades) using the full range of his swordsmithing techniques. Prized for their refined appearance and superb edge retention, these pieces offer a more accessible window into the world of a true sword master.
