About us

A leather that you can always meet new delight

In order for leather to continue to breathe in the future, we believe that it is important to create products that "have the character of leather".
Leather has been used as a tool long before it was used for fashion.
It is necessary for the original character of leather to become the starting point, not something that exists as a fad in our efficient lives.

MINA blue, based in Japan, seeks to create a rich lifestyle based on "Hand-Matured Chrome Leather" a leather originally developed by MINA blue.
