An utsushi is a copy of someone else’s work. This kind of copy was not meant to deceive. In most cases the source work is a masterpiece that has achieved some recognition. In creating the utsushi a craftsman is both challenging himself to make a work in the style of the past master, learning about the techniques required to make a work in this style, and as well pay homage to artwork he holds in high esteem.
Some of these copies make alterations or simply draw inspiration from the work that came before them. This kind of work would be done in the style of the predecessor so that it could fit in amongst their repertoire. Others were made exactingly as a note for note rendition of the previous work. In some of these cases the craftsman has the item on hand he is trying to copy. In others, he is working from drawings, or notes of the work. These notes or drawings may be incomplete or may be themselves just approximations of the piece in question.
Some of these utsushi can be quite interesting as the work that they are copying is now lost. In some cases, we can assume that the work was indeed copied but the utsushi copies are now lost.
