■What is Himeji KUROZAN leather ?
Himeji Kurozan Leather is a premium leather crafted by combining traditional Japanese tanning techniques with lacquer coating technology. Known as the "Black Diamond of Leather," Kurozan Leather exhibits a mesmerizing shine, resembling countless tiny diamond-like particles scattered across its surface.
This leather is exceptionally durable and resistant to friction, making it a preferred material for kendo armor (dō-mune) and other martial arts equipment. Historically, it was also used for samurai armor worn by high-ranking commanders during the Sengoku period.
A masterpiece born from two essential techniques—the art of tanning that enhances the natural beauty of leather and the precise lacquer coating that maximizes the elegance of the grain surface—Himeji Kurozan Leather stands as a true work of craftsmanship.
Types of Kurozan Leather Grain Patterns
Kurozan Leather comes in three grain variations:
- Embossed (Kataoshi)
- Hand-Rubbed Premium Kurozan (Gokujou Kurozan)
- Ultimate KIWAMI (KIWAMI)
The leather used in this product is Embossed Kurozan, which features a fine and uniform grain, making it an ideal choice for watch straps. Even with the Embossed finish, the material cost is several times higher than that of standard cowhide leather.

It goes perfectly with dress watches, and if you have a domestic watch, strap is also a great item to coordinate with "THE Japanese leather". If you are looking for a unique strap, please try this opportunity.
*For installation widths of 18 and 19 mm, two types of buckle widths are available: 16 mm and 15 mm. When ordering, please specify the buckle width.
*The color and texture of the leather may differ slightly depending on the lot.
*We use leather whose lacquer has completely dried and hardened, but depending on your constitution and physical condition, you may occasionally get a rash. In that case, stop using the strap and consult a specialist.

持っているオメガシーマスターにつけてみました。
シルバーのフェイスになかなか似合っていてよかったです。
が、残念ながら肌が漆に敏感だったせいで、装着初日から遊革(サル革)部分の内側部分の肌がかぶれてしまいました。ベルト自身の裏側は大丈夫なようですが、シボ加工部分だけかぶれちゃいました。残念です。
レビューをご投稿いただき、またオメガ・シーマスターとの素敵なコーディネートをお試しいただきありがとうございます。せっかくデザインを気に入っていただけましたのに、遊革部分で肌かぶれが起きてしまったとのこと、大変心苦しく、深くお見舞い申し上げます。その後お肌の調子はいかがでしょうか。
当商品の「姫路黒桟革」は、伝統的な製法に基づき本漆を使用して仕上げております。漆は乾燥・硬化してしまえば基本的にはかぶれにくい素材ではございますが、体質や体調、または汗などの水分による影響で、稀に敏感な肌が反応してしまうことがございます。特に遊革など、肌に密着して擦れやすい部分は症状が出やすくなる可能性がございます。
貴重なご意見を真摯に受け止め、今後の商品説明(漆に関する注意表記)の改善に努めてまいります。何かございましたら、いつでもショップのお問い合わせ窓口までご連絡くださいませ。
