Master the Way of the Daimyo – Wear History’s Strongest Armor

The Okegawa Ni-Mai Gusoku is the quintessential armor style perfected in the final decades of Japan’s Sengoku Era (Warring States Period). Known as tosei (modern) armor, it marked the evolution of samurai warfare—designed to be stronger, more efficient to craft, and better suited for the gunpowder battlefield.

Featuring ito-mono (long steel plates) overlapped and riveted together horizontally, this armor set became the new standard for all ranks of samurai, from ashigaru (foot soldiers) to noble Daimyo. The ni-mai dō (two-piece cuirass) was joined by a pin hinge on one side and tied on the other, allowing for better adjustability, lighter weight, and faster movement without sacrificing protection. Its full traditional name is Tosei Yokohagi Okegawa Ni-Mai Dō—a true innovation of the late Sengoku era.

This Daimyo Class Okegawa armor is handcrafted by our most senior katchû-shi (Japanese armor smiths) at Iron Mountain Armory, blending traditional designs with modern material enhancements to create a more lavish, prestigious appearance. Every gusoku is a tribute to the warrior nobility of feudal Japan, worthy of a Daimyo’s command.

Standard options pre-selected for this set include the powerful hachi goshōzan kabuto (victory mountain helmet), but customization is encouraged. Choose a zunari (head-shaped) kabuto for a classic battlefield look or a momonari (peach-shaped) kabuto for late Sengoku flair. Every detail—paint colors, odoshi (lace), menpō (mask), suneate (shin guards), and more—can be tailored to honor your personal warrior spirit.

This armor set is not only breathtaking in its craftsmanship but fully functional for bujutsu training, reenactment, LARP, cosplay, or to be proudly displayed as the centerpiece of your samurai collection.

Key Features & Benefits:

  • Daimyo Class crafting by senior Iron Mountain Armory artisans

  • Full-sized and fully functional for battle or ceremonial display

  • Overlapping yokohagi (horizontal) plating for enhanced protection

  • Pre-set customization with full ability to further personalize color, kabuto, mask, & more

  • Includes deluxe display box & stand for showcasing your legacy

Shipping Information:

Handcrafted with extreme care by our senior katchû-shi. Please allow at least 1 to 2 months for crafting and preparation before your custom armor set is ready to ship.
