Armour Society Designation
Kōshū Tokubetsu Kichō Shiryō甲種特別貴重資料
First-Class Especially Valuable Reference Material
›

The first-class (kō-grade) of the especially-valuable rank and the society’s second-highest grade, reserved for armour of exceptional importance.

About the Armour Society›

Japanese armour is not certified by the NBTHK. The Nihon Katchū Bugu Kenkyū Hozon Kai (the Association for the Research and Preservation of Japanese Helmets and Armour), founded in 1961, is the principal body for armour. Its shinsa grades a piece as 資料 (shiryō, "reference material") across five ascending ranks: Hozon, Kichō, Tokubetsu Kichō, Kōshū Tokubetsu Kichō, and the highest, Jūyō Bunka Shiryō. The 資料 framing reflects the society’s purpose of preserving armour as cultural and historical reference, distinct from the NBTHK’s sword paper tiers.
