Aoi Art\u2019s Comment: This is a Daisho by Tsunahide of Yonezawa, Dewa province, with identical t\u014dranba hamon.
\nBoth blades come with koshirae and sayagaki by Kansan Sensei.
\nThis type of Daisho is extremely rare, with both pieces believed to be made around the same time.
\nWe highly recommend this fine set.
\nThese swords were once registered as a Daimyo’s Daisho under Niigata Registration Numbers 231 and 236, both dated March 31, Showa 26 (1951), and were likely cherished as a pair even before the war.<\/p>\n
Historical Context: The Bunkyu era was marked by exploration, such as Mamiya Rinz\u014d\u2019s expedition to Sakhalin and the discovery of the Mamiya Strait.
\nDuring this time, foreign powers began to pressure Japan to end its policy of isolation, leading to increased visits from overseas.<\/p>\n
