Authentic Japanese Craftsmanship — KUSAKURA（九櫻）

KUSAKURA is a respected Japanese manufacturer specializing in traditional martial arts uniforms and equipment.

The R3N Black #11 Cotton Uniform reflects the manufacturer's commitment to traditional construction, functional design, and the demanding requirements of Japanese martial arts practice.

Unlike lightweight martial arts uniforms, the R3N features a substantial yet flexible cotton fabric designed to provide comfort and durability during regular training.

Manufactured in Japan, this model is an excellent choice for practitioners who value authentic Japanese martial arts equipment.

Medium-Weight #11 Cotton Canvas — Comfort and Durability

The KUSAKURA R3N is manufactured from 100% cotton, Grade #11 Japanese canvas (11号生地).

The material is particularly suitable for training involving body movement, changes of posture, evasive techniques, and repeated martial arts practice.
