Yamatorige
Also known as: Mountain Bird Feather
Description
Yamatorige ('Mountain Bird Feather') is a tachi attributed to Ichimonji Norimune, the founding master of the Bizen Ichimonji school, forged in the early Kamakura period. It was the most beloved sword of Uesugi Kenshin, who is said to have declared it the supreme treasure of Echigo Province and ordered in his final testament that it must never leave the Uesugi family. The name derives from the blade's magnificent hamon — a rich chōji-midare temper pattern said to resemble the splendid feathers of the yamadori (copper pheasant), a bird native to Japan. In 2019–2020, the city of Setouchi in Okayama Prefecture raised over 670 million yen through crowdfunding to purchase and repatriate the sword to its birthplace in Bizen Province — one of the largest cultural property crowdfunding campaigns in Japanese history.
Legends & Stories
Kenshin's dying testament reportedly included the words: 'Yamatorige is the supreme treasure of Echigo Province. It must not pass outside the family.' He died in the spring of 1578, at forty-nine, in the middle of planning another military campaign — sudden, unexpected, leaving the Uesugi domain in chaos. His sword outlasted the civil war that followed, outlasted the reduction of the domain after Sekigahara, and outlasted the Uesugi clan's diminishment from a great power to a minor domain. Then, in 2019, it came up for auction. The city of Setouchi in Okayama — the birthplace of the Bizen tradition — launched a crowdfunding campaign to bring the sword home. Six hundred and seventy million yen flowed in from Japanese people across the country who had never met each other but shared a conviction that this particular object mattered. The sword returned to Bizen. Kenshin's testament said never to let it leave Echigo; instead it returned to the forge that made it. Perhaps that, too, is a form of homecoming.
