The Haitōrei edict of 1876 ended sword wearing and nearly ended the craft itself. Military demand and imperial patronage kept a remnant alive, and in 1906 Gassan Sadakazu and Miyamoto Kanenori were named Artists to the Imperial Household.
This is a tachi made by Gassan Sadakazu in 1901 for Mizusawa Masao. It features a reverse choji-midare hamon, likely aiming for the Bizen-den Katayama Ichimonji style. The blade comes with a koshirae and is certified as Hozon Token by the NBTHK.
