Various Dignified Belly Warmers (with Helmet and Sleeves)

The Back-Fastening Armor Attributed to Uesugi Kenshin

This armor closes down the back rather than the side. That single feature marks it as a haramaki, a class of Japanese body armor that a warrior could wrap around the torso and tie shut between the shoulder blades. The suit kept at Uesugi Shrine in Yonezawa, Yamagata Prefecture, carries the full name Iro-iro Odoshi Haramaki, complete with helmet and tube sleeves. By tradition it belonged to Uesugi Kenshin (1530-1578), the warlord of Echigo Province whose long contest with Takeda Shingen made him one of the most studied commanders of Japan's Sengoku age.

The term iro-iro odoshi means "various-colored lacing." Armor of this kind was built from hundreds of small scales, or kozane, bound together with braided silk cords called odoshi. When three or more cord colors ran across a single suit, the result took the name iro-iro odoshi. Accounts of this piece cite purple and crimson among its colors, though descriptions differ on the exact palette. At the brow of the helmet sits the front crest, or maedate, shaped as Izuna Gongen, a mountain deity invoked for victory in war. Kenshin's documented religious devotion makes that choice apt, even if the bond with the man himself rests on tradition rather than an inscription.

A Muromachi Form, Designated in 1959

Three main armor types served Japanese warriors through the medieval centuries. The o-yoroi, boxy and heavy, suited the mounted archers of the Heian and Kamakura periods. The domaru wrapped the body and fastened at the right side. The haramaki, lightest of the three, opened and closed at the back.

Early haramaki were the gear of foot soldiers. By the late Muromachi period (1336-1573), high-ranking warriors had adopted the form for its lighter weight and freedom of movement, often dressing it up with a helmet and sleeves for formal occasions. This suit belongs to that later, elevated line of haramaki.

Japan's Agency for Cultural Affairs designated the armor an Important Cultural Property on December 18, 1959, recording it as a single suit of the Muromachi period. An Important Cultural Property ranks one tier below National Treasure in the national protection system; the category gathers objects of high historical or artistic value selected from across the country. A black-lacquered armor chest is registered alongside the suit as an attached item. The Agency's own entry leaves the dimensions and detailed construction blank, so the finer measurements that circulate in popular accounts deserve a measure of caution.

What to Look For

The Izuna Gongen crest repays a close look. The deity is commonly shown as a winged, beaked figure riding a fox, an image that fuses Buddhist and folk-religious traditions. Set above the helmet's peak, it declared the wearer's appeal for divine protection before a single blow fell.

The lacing rewards patience too. Silk cords of contrasting color run in horizontal bands across the scales, and the shift from one shade to the next gives the surface its rhythm. Specialists describe this suit as larger than most surviving haramaki, closer in scale to a domaru, which hints that it was built for a tall or broad wearer rather than reworked from a foot soldier's kit. The tube-shaped sleeves, or tsubosode, and the rear closure read most clearly when the armor stands on a display frame rather than lying flat.

The Keishoden and the Castle Grounds

The armor is housed at the Keishoden, the treasure hall of Uesugi Shrine. The shrine occupies the former main enclosure of Yonezawa Castle, today the green sweep of Matsugasaki Park, and enshrines Kenshin himself. The Uesugi clan settled in Yonezawa in 1601, carrying their founder's relics with them. That relocation is why so much of Kenshin's material survives here, far from his native Echigo on the Japan Sea coast.

The Keishoden building deserves attention on its own. Completed in 1923 to a design by Ito Chuta, the Yonezawa-born architect behind Tokyo's Tsukiji Hongan-ji, it counts among the early reinforced-concrete museum buildings in Japan and is itself a Registered Tangible Cultural Property. Inside, several hundred Uesugi heirlooms rotate through the cases. The most photographed neighbor of the haramaki is the armor of Naoe Kanetsugu, the chief retainer of Kenshin's heir, topped by a helmet bearing the single character "Ai" (love).

Displays change on a schedule, and the hall shuts through the snowbound winter, reopening in spring. Anyone making a special journey to see this particular armor should confirm in advance that it is on view. Yonezawa is reached by train, and the shrine lies a short bus ride or walk from Yonezawa Station.
