It is a work of art that is made up of two technologies: "tanning technology" that brings out the appeal of natural leather and "sever coating technology that makes full use of beauty of the leather."
Himeji Black Leather is a fusion of the traditional Japanese technique of "tanning" and "lacquering" using Japanese black beef. The black leather strap, which is synonymous with"black leather diamond", is as beautiful as a large number of small diamond particles. It is also highly resistant to friction and is now used for armor tools such as kendo chest and chest, and during the Warring States period, it is said to have been used for general-class armor.
