This kozuka features a Miyako-dori-zu (都鳥図), depicting miyako-dori, birds that have long appeared in classical Japanese poetry and painting as symbols of elegance and nostalgia. The kozuka is made of shibuichi (四分一), a traditional Japanese alloy composed mainly of copper and silver. The birds are rendered in takabori (高彫, high-relief carving) and delicately embellished with zōgan (象嵌, metal inlay) and iroe (色絵, colored-metal decoration). According to the NBTHK appraisal, this kozuka bears the signature of Genki (元輝), a metalworker active during the Edo period. Surviving works attributed to him include refined depictions of birds and hazy moonlit scenes, demonstrating the same delicate use of metal inlay and colored-metal decoration seen in this piece. Authentication Paper They authenticated the Kozuka on October 27th in the 20th year of Heisei (2008). They appraised it as Hozon Tousougu, the Kozuka worth preserving for Japanese society.
