    Extra Customization 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.

Forge Your Legacy with the Armor of the Arima

The Arima Clan Samurai Armor honors a remarkable warrior lineage descended from Fujiwara Sumitomo and founded by Arima Tsunezumi in the 12th century. Known for their cavalry and deep ties with Portuguese Christian missionaries, the Arima became one of the first Japanese clans to embrace foreign military tactics and weaponry. Their name—“Arima,” meaning “has horse”—is a direct nod to their fierce mounted warriors.

In the mid-16th century, the Arima received military support from Portuguese allies, including firearms and advanced weaponry, increasing their battlefield effectiveness. Though a relatively small clan, their loyalty and foreign alliances helped shape the final years of the Sengoku period. They ultimately aligned with Toyotomi Hideyoshi, playing a vital role in the unification of Japan. The Gashira samurai of the Arima Clan were hand-picked to lead their Kachi warriors and take direct commands from the Taisho in battle.

This suit of yoroi is handcrafted by senior katchû-shi using the traditional Tosei Byō-tōji Yokohagi Okegawa Dō—a two-piece cuirass made with riveted horizontal plating and joined with a pin hinge. It also features kiritsuke iyozane (simulated scale plating), sode (shoulder guards), and kusazari (defensive skirt). These armor elements were common in the later Sengoku period, offering a fine balance of flexibility and protection.

The Arima Clan preferred a suna (sand-textured) finish with black odoshi (lace), projecting both mystery and discipline. Iron Mountain Armory is honored to offer full customization, from paint colors and textures to lace patterns, helmet and mask styles, and shin guards. Make your suit stand out while preserving the integrity of its historical inspiration.

Key Features & Benefits:

  • Gashira Class craftsmanship with traditional Sengoku-era styling
  • Byō-tōji Yokohagi Okegawa Dō and kiritsuke iyozane simulated scale plating
  • Fully customizable helmet, menpō, paint, lace & size
  • Full-sized & fully functional armor
  • Includes display box & stand

Shipping Information:

Each armor set is custom handcrafted by our skilled katchû-shi. Please allow at least 2 weeks for processing & crafting before your armor is ready to ship.
