Sengoku Samurai Armor: Full Sized, Wearable & Functional Armor

Description

Forged for Battle – Armor of the Warring States Elite

The Sengoku Go-Mai Yoroi is a historically significant and visually commanding Taisho-class yoroi (armor set), expertly crafted by the senior katchû-shi (Japanese armor smiths) at Iron Mountain Armory. Inspired by an original piece from the Sengoku Era (Warring States Period), this armor is a testament to innovation and evolution in samurai protection.

Featuring a go-mai dō (five-section cuirass) joined by four robust hinges, this design became one of the most advanced and resilient tosei gusoku (modern armors) of the era. Its segmented structure provided exceptional durability while offering modular flexibility for repairs, upgrades, or size adjustments—making it a favorite among seasoned samurai. The armor is built in the yokohagi-okegawa configuration with ita-mono (solid horizontal plates), delivering both functionality and visual prestige.

The Sengoku Go-Mai Yoroi is traditionally worn without sode (shoulder guards), emphasizing a stripped-down, combat-focused aesthetic; however, we include a matching set of sode for those seeking a more complete look. This set is pictured with an Etchū Zunari Kabuto (helmet) featuring mayu (simulated eyebrows), a detail you can customize along with the style of your kabuto, menpō (face mask), color scheme, and armor fit.

This yoroi is a refined example of late-Sengoku battlefield armor, crafted to convey power, discipline, and nobility. Whether for martial arts use, collection, or ceremonial display, it serves as an iconic reminder of the warrior’s path.

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.
