Sakakibara Yasumasa Samurai Armor – Guardian of Tokugawa

The Guardian King – Loyal to Tokugawa, Unmatched in Honor

The Sakakibara Yasumasa Samurai Armor is a proud tribute to one of the most respected and loyal daimyo of the late Sengoku Jidai through the early Edo period. Sakakibara Yasumasa (1548–1606) stood as the Tokugawa Clan’s most trusted general and strategist. Alongside three other legendary daimyo, he became known as one of “The Four Guardian Kings” – protectors of the Tokugawa legacy and fierce defenders of unification-era Japan.

This Gashira Class gusoku (samurai armor set) is designed with pride and attention to the legacy of Yasumasa. Crafted with a traditional hachi zunari kabuto (helmet with a bowl shape reminiscent of the human head) and a Byō Tōji Yokohagi Okegawa Dō (rivet-embellished horizontal-lame cuirass), this suit balances battlefield strength with refined elegance. The chest and skirt (kusazari) feature kebiki-odoshi (full lacing), demonstrating the warrior’s rank and the detail of our katchû-shi (Japanese armorers).

This armor is finished in a brown suna (sand texture) lacquer with bold red, white, and blue odoshi (lacing) – symbolizing courage, purity, and loyalty. The tall maedate (crest) crowns the kabuto, marking this armor as one belonging to a samurai of vision and valor. Whether for reenactment, martial arts, cosplay, or display, this suit is a fitting legacy piece.

Our Gashira Class armors offer upgraded craftsmanship and detail over our Kachi series. All armor is made with full wearability and authentic display in mind. Customize your set with alternate helmet styles, mask options, and shin protection via our Extra Options menu.

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.
