Uesugi Shrine Keishoden

Uesugi Shrine Keishoden is a treasure hall on the grounds of Uesugi Shrine in Yonezawa City, Yamagata Prefecture, which opened in 1923 (Taisho 12) alongside the reconstruction of Uesugi Shrine. The multi-tiered building, designed by Yonezawa-born architect Ito Chuta, is registered as a national Tangible Cultural Property. It is a separate facility from the Yonezawa City Uesugi Museum (Denkoku no Mori), operated independently by Uesugi Shrine itself.

Uesugi Family Sword and Armor Collection

Keishoden houses and displays a wide range of materials from the Heian through Edo periods, centered on relics of successive Uesugi lords — Uesugi Kenshin, Uesugi Kagekatsu, and Uesugi Yozan — as well as senior retainer Naoe Kanetsugu. These include armor, weaponry, swords, paintings, calligraphy, Buddhist ritual implements, ceramics, and clothing, and the collection includes items designated as national Important Cultural Properties and prefecture- or city-designated Cultural Properties. The shrine grounds stand on the site of the inner palace of the honmaru of Yonezawa Castle, a location that also carries symbolic significance for tracing the history of the Uesugi family.

Notable Holdings

Highlights include armor said to have been worn by Naoe Kanetsugu, featuring the famous "Ai" (love) crest on its front ornament; the Important Cultural Property "Iroiro-odoshi Haramaki" armor worn by Uesugi Kenshin; and the Yamagata Prefecture-designated "Murasaki-ito Odoshi Iyo-zane Gomai-do Gusoku" armor worn by Uesugi Kagekatsu. These artifacts trace the concrete history of the Uesugi family's warriors, and the Sengoku through Edo period history of the Uesugi family can be followed specifically through the actual objects. The displays are rotated regularly, so visitors can encounter different items depending on the season and special exhibitions, which is another feature of Keishoden.

Architecture and Access

The Keishoden building itself is a highlight, with its multi-tiered roof design counted among Ito Chuta's representative works. The hall closes during winter (late November to mid-March), but it is open during the Uesugi Snow Lantern Festival in February. Located right beside the "Uesugi Jinja-mae" bus stop, reached by community bus from Yonezawa Station, it draws many visitors who combine their visit with worship at Uesugi Shrine. Because it is an independent facility operated by a different entity from the Denkoku no Mori / Yonezawa City Uesugi Museum, visiting both allows a more layered understanding of Uesugi family history.
