Although it is believed that Nagata Yûji lived during the time of Seitoku (1711-1716) and Kyôhô (1716-1736), this has not yet been concretely established. Old books from the time say that he admired Ogata Kôrin (1658-1716) very much and mastered his styles and techniques. He chose the name, Seseishi (Disciple of Kôrin), as ""Seisei"" was another name for Kôrin. He belonged to the Rinpa School.
This inkstone case has a design of a male and a female deer at the waterside done in <i>makie</i>, plates of tin and lead, and mother-of-pearl inlay. The designs inside also employ the style of the Rinpa School. Although there are a number of works that bear the signature or seal of Yûji, there are very few large-scale works produced by him. For this reason, this inkstone can be counted as one of his masterpieces. Yûji was a unique artist who produced original works in the Edo period (1615-1868).
