Ichinomiya Nagatsune was born in 1721 in Tsuruga of Echizen. He used the name Kashiwaya Chuhachi and originally started his career as a metal plating craftsman before moving to Kyoto to study under Yasui Takanaga of the Goto School. In his early years, he used the artistic name Setsuzan, and later changed his name to Nagatsune using the artistic name Ganshoshi. He also studied painting under Ishida Yutei, who was the teacher of Maruyama Okyo. While Nagatsune was skilled in the takabori style of Goto, he was most known for combining katakiribori with flat inlay, and was well acclaimed with the reference “Somin representing the east, and Nagatsune the west.” Together with Tetsugendo Shoraku and Otsuki Mitsuoki, he was also known as one of the three great metal craftsmen of Kyoto. At the age of 50, he received the title of Echizen Daijo, and passed away in the 6th year of Tenmei (1786) at the age of 66. This piece features a motif of flocking cranes executed on a polished shibuichi base with various inlayed colored metals. This excellent work features well defined and deep carving, with details of the beak and feathers depicted in a variety of katakiribori, a style hallmark to Nagatsune and attesting to his remarkable skill. This motif is included in Nagatsune’s sketchbook.
