    Extra Design Options


    Gashira (Officer):
    Expertly handmade from a mixture of quality traditional and modern materials, as well as some modern crafting process. This class of armor is crafted with a good attention to detail.


    Crafting Time: 20 to 35 Days.


    Materials Used: Bowl style kabuto, steel construction, traditional brocade, hemp, quality cotton, brass, copper fittings with genuine leather & and some synthetic materials might be used. (materials may differ depending on model)



    Our “Gashira Class” yoroi represents the next level up from our “Kachi Class.” Each suit is meticulously handcrafted by our experienced katchû-shi (armor smiths) at Iron Mountain Armory. These artisans pour their warrior spirit into every piece, using quality materials and traditional crafting methods, complemented by modern techniques, tools, and design advancements. Like the Taisho Class, each suit is heavily researched and crafted with great care for historical accuracy. The principal difference between the Gashira and Taisho classes is that the Gashira Class is crafted with a practical bowl-style kabuto (simulated laminate) and some machine-stamped parts. The Gashira Class also features subtle modern enhancements, such as grommets and spot welding, making the armor more robust and easier to maintain. Our Gashira Class samurai armor is made for collectors, exhibitions, re-enactors, and martial artists who desire an authentic “Gendai” samurai suit of armor without the additional expenses associated with the more traditional design and handcrafting methods of our Taisho Class.




    The Gashira Class features a more traditional Gendai design compared to the Kachi Class and includes features such as real animal hair, genuine leather, a removable or interchangeable nose, brass fittings, shoulder padding with kikko (armor plating), traditional butted mail, opposable thumbs, leg/waist support on haidate, extra materials, fittings, riveting, grommets, additional lacing options, and an included armor storage/display box (yoroi bitsu) with stand. The attention to detail is a significant step up from the Kachi Class. However, due to the handcrafted nature of many parts, there may be some blemishes that pass through our QC process. Although we strive to avoid and correct these blemishes, they are a natural occurrence in handcrafting. Taisho Class suits will have fewer, if any, of these blemishes due to the high standards and meticulous review processes.

Lead with Fearless Honor – The Red Ogre Rises Again

Ii Naomasa Taisho Samurai Armor set has been handcrafted in honor of the legendary Ii (Ē) Naomasa (井伊 直政, 1561–1602) of the Tôtômi Province. Revered as one of the “Four Guardian Kings” who defended the Tokugawa Shogunate, Naomasa stood as a symbol of fearless command and indomitable spirit. Inspired by the fabled Takeda Clan, he and his troops donned armor in rich vermilion, creating a terrifying presence on the battlefield. This earned his elite forces the fearsome name “The Red Devils,” while Naomasa himself was called Akaoni (Red Ogre).

This remarkable yoroi set features Naomasa’s signature “lofty golden horns,” rising from the etchû zunari kabuto (helmet) in place of a traditional maedate (crest). The kiritsuke iyozane okegawa dō (simulated scale plated cuirass with horizontal plates) is both functional and ceremonial, combining protection with regal aesthetics. As with the original, the visual emphasis on fearlessness and authority commands respect both in combat and in presentation.

Our most experienced katchû-shi (Japanese armorers) at Iron Mountain Armory replicate this historically important design using traditional techniques with minimal modern tooling. Whether worn in martial demonstrations or proudly displayed, this Taisho-class armor is a tribute to honor, duty, and the spirit of conquest.

Clients can personalize this armor with changes to the color of the horns, their size, or other available features. Simply note your preference in the “Order Comments” section during checkout.

Key Features & Benefits:

  • Taisho Class craftsmanship – elite hand-forged quality
  • Full-sized, fully functional for training, reenactment, or display
  • Rich vermilion finish with high-quality cotton odoshi (lace)
  • Includes wooden display stand & armor storage box (yoroi bitsu)

Shipping Information:

Our most experienced Taisho katchû-shi will begin handcrafting your custom armor upon order. Please allow at least 2 to 3 weeks for completion. This heirloom-quality yoroi is a true once-in-a-lifetime investment—crafted to perfection, forged in honor.

Command with Courage – Fear None, Earn All
