What is Uramei in Japanese Katana terminology?

"Uramei" (裏銘) refers to the inscription carved on the reverse side of a Japanese sword, specifically on the ""Sashiura"" (差裏) or ""Hakiura"" (佩裏). These inscriptions typically include information such as the date and location of the sword's creation, the name of the owner, and test cutting inscriptions. In some cases, special inscriptions may also be included, such as the material used for the sword, the names of co-creators, and other unique details. When the inscription includes the date of creation, it is specifically referred to as "Uranenki" (裏年紀).

This practice of inscribing details on the reverse side of the sword serves multiple purposes. It provides valuable information about the sword's history and provenance, aids in the identification and authentication of the sword, and adds to the overall aesthetic appeal of the sword. It is an integral part of the artistry and craftsmanship that goes into the creation of a Japanese sword."
