HOME > For Himeji Kurozan
Himeji Kurozan leather, made from Japanese Kuroge Wagyu cattle, combines the traditional Japanese techniques of tanning and lacquering. Kurozan, also known as the “Black Diamond of Leather,” is a beautiful type of leather that appears to be strewn with a countless number of small diamonds. Because of its strong resistance against friction, today it is utilized in martial arts equipment such as chest and trunk protectors for Kendo.
It is said that this leather was used to make armor and helmets for generals during the Sengoku (Warring States) Period.
Production of Kurozan leather
SAKAMOTO CORPORATION carries out the entire production process spanning from tanning to processing.
All fur is removed from rawhide of Kuroge Wagyu, which is then tanned to a white color and soaked in plant tannins.
We have used this tanning technique for nearly 10 years.
Next, the leather is soaked in liquid iron.
The liquid itself is not black, but the tannins and iron have a chemical reaction that dyes the light-brown leather to a black shade.
The texture of Kurozan leather includes embossed, hand-rubbed and KIWAMI types.
Lacquer is repeatedly applied to the bumpy texture by hand and then dried.
These multiple layers of lacquer create a sense of luster and volume, and also enhance the glossiness of the black color.
Only a small amount of rare Kurozan leather can be completed via labor of this sort.
Even a dedicated craftsman can only make around 20 pieces per month.
