For Himeji Kurozan

Bring out the charm of natural leather "tanning of technology" and "tough coating technologies that take advantage of the beauty of the leather of Gin-men" It is a work of art that is made from two of the technology.

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.

Kurozan leather Working process

Kurozan leather Working process

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.

Kurozan leather for the『KIWAMI』

At the 2014 Hong Kong Asia Pacific Leather Fair-Materials, Manufacturing & Technology Exhibition (APLF-MM&T), Himeji Kurozan leather KIWAMI was the first Japanese product to win the Best New Leather Prize. In this tanning technique, the leather is not only kneaded by hand but also processed in other ways to create a bumpy texture. To make this Japanese leather—based on the principle of “fluidity and immutability”—we utilize the lacquer’s characteristic drying and hardening properties and leverageour tanning and lacquering techniques to draw out the leather’s charm to the maximum degree. The judges praised the usage of traditional leather, which has existed since the time of Samurai, in the realm of contemporary fashion such as bags, shoes, etc.
