Denko-no-Mori Yonezawa Uesugi Museum is a history museum in Yonezawa, Yamagata Prefecture. Located next to Matsugasaki Park, which occupies the former site of the main compound of Yonezawa Castle, the museum houses and displays valuable historical materials related to the Uesugi family and the history and culture of Yonezawa.
The museum’s collections focus particularly on cultural properties associated with the Uesugi family, which ruled Yonezawa from the Sengoku period through the Edo period. Visitors can see historical documents, maps, materials related to samurai culture, and other objects that provide insight into the region’s past.
Among the museum’s highlights are the National Treasures “Uesugi Rakuchu-Rakugai Zu Byobu”, a pair of folding screens depicting Kyoto, and the “Uesugi Family Documents”. Exhibits also introduce the administrative reforms of Uesugi Yozan, the ninth lord of the Yonezawa Domain. The museum therefore offers a broad introduction not only to the Uesugi family but also to the culture and development of Yonezawa.
One of the museum’s most important cultural treasures is the National Treasure known as “Rakuchu-Rakugai Zu”, or the “Uesugi Rakuchu-Rakugai Screens”. The work is traditionally said to have been presented by Oda Nobunaga to Uesugi Kenshin in 1574. It was subsequently passed down within the Uesugi family after they became lords of the Yonezawa Domain.
The screens are traditionally attributed to Kano Eitoku, one of the leading painters of the Momoyama period. The composition provides a panoramic view of Kyoto, depicting scenes from both the city and its surrounding areas throughout the seasons. Temples and shrines, famous landmarks, festivals, animals, plants, and everyday activities are rendered in remarkable detail.
The screens are said to contain approximately 2,500 individual figures. Aristocrats, samurai, merchants, craftsmen, and ordinary townspeople appear throughout the composition, providing clues about society and daily life in Kyoto during the period.
In addition to the people, the screens depict temples, shrines, buildings, religious festivals, animals, and plants with great attention to detail. The work is an especially valuable source for understanding the appearance and atmosphere of Kyoto during the Momoyama period and is regarded as an important example of Japanese art.
The museum normally displays a carefully reproduced replica of the National Treasure. On special occasions, including exhibitions held in spring and autumn, the original screens may be displayed for a limited period.
In addition to permanent and special exhibitions, the museum hosts lectures, workshops, and other educational programs. These activities provide visitors with different ways to explore the world depicted in the Uesugi Rakuchu-Rakugai Screens.
A large screen inside the museum presents explanatory videos about the streets of Kyoto and the lives of the people depicted in the Uesugi Rakuchu-Rakugai Screens.
Some of the visual presentations are based on figures actually portrayed in the folding screens. This makes it easier for visitors to imagine how people lived and interacted within the intricate scenes depicted in the artwork.
A byobu, or Japanese folding screen, is a traditional furnishing made of connected panels that can be folded and unfolded. It was originally used to block wind and create privacy or divide interior spaces.
By the early Muromachi period, the “rokkyoku-issho” format, consisting of two sets of six connected panels, had become an established form. Folding screens were decorated with many different subjects, including landscapes, people, flowers, and birds.
During the Edo period, artists also produced numerous battle-scene folding screens, which depicted famous military campaigns and historical events.
Another major highlight is the National Treasure known as the “Uesugi Family Documents.” This collection consists of historical documents that were passed down through the former lords of the Yonezawa Domain. The documents cover a broad period from the Kamakura period through the Edo period.
The collection comprises 2,018 individual documents, four albums, and 26 bound volumes. In 2001, it became the first collection of samurai-related documents to be designated a National Treasure.
The Uesugi Family Documents include not only records from the period of Uesugi Kenshin and his successors, but also documents inherited by the Yamauchi-Uesugi clan, which was based in the Kanto region, and the Nagao clan, which was based in Echigo.
These materials provide valuable information for tracing the history of the Uesugi family. They also offer insights into politics, society, and relationships among samurai families from the Sengoku period through the Edo period.
One of the most notable features of the Uesugi Family Documents is that many were preserved without being remounted or reformatted into scrolls or other presentation styles in later generations. As a result, they retain forms relatively close to those in which they were originally transmitted.
Details such as the way documents were folded and wrapped have also survived. These features make the collection valuable for understanding how written documents were handled within samurai society and for studying traditional rules of letter writing and document etiquette.
The museum’s permanent exhibition area, known as the Uesugi Bunka-kan, introduces selected materials from the Uesugi Family Documents. Because the displayed items are regularly changed, visitors may encounter different documents depending on when they visit.
The museum also features the “Yozan Theater,” an exhibition space introducing the life and administrative reforms of Uesugi Yozan, the ninth lord of the Yonezawa Domain.
The displays combine a variety of presentation methods, including dramatic videos featuring actors, graphics incorporating techniques associated with Yonezawa’s textile industry, and dioramas recreating the Okitama region and the castle town of Yonezawa as they might have appeared in the past.
The exhibition explains how Yozan attempted to rebuild the financially troubled Yonezawa Domain through administrative and economic reforms. The presentation is designed to make the subject accessible even to visitors who are not familiar with Japanese history.
Yonezawa Uesugi Museum introduces a wide range of cultural properties related to the Uesugi family as well as materials documenting the history and culture of Yonezawa and the wider Okitama region.

Through these cultural properties, visitors can follow the long historical development of the Uesugi family, from the Sengoku-period warriors to the Uesugi lords who governed the Yonezawa Domain during the Edo period.
Upon entering the museum, visitors encounter a Noh stage displayed in the entrance hall. This stage is not merely a museum exhibit. During Noh and Kyogen performances, it can be raised slightly from the floor using an air-floating system and moved into the hall to serve as the performance stage.
The Okitama Cultural Hall is a performance venue with approximately 500 seats. It hosts concerts, theater performances, and other cultural events and is equipped with a movable Noh stage.
The ability to move the Noh stage displayed in the entrance area to the main stage using an air-floating system is one of the distinctive features of Denko-no-Mori.
An observation room is located beyond the permanent exhibition galleries. From here, visitors can look out toward the surrounding facilities and landscape. It provides a pleasant place to take a short break after exploring the exhibitions.
The museum also has a museum shop selling original goods inspired by historical figures associated with Yonezawa, including Uesugi Kenshin, Uesugi Yozan, and Naoe Kanetsugu.
The selection includes items for history enthusiasts as well as souvenirs that make memorable keepsakes of a visit to Yonezawa.
The museum also displays a “Gyoya,” a traditional building associated with the mountain-worship traditions of the Okitama region.
Mountain worship centered on places such as Mount Iide and the Dewa Sanzan mountains once flourished in Okitama. In the past, boys around 13 to 15 years old traditionally climbed these sacred mountains as part of a rite of passage into adulthood. Before making the pilgrimage, they would use buildings such as the Gyoya to purify themselves.
A Gyoya was used as a place where pilgrims stayed for a certain period before their mountain pilgrimage and performed purification rituals such as water purification. The building on display at the museum was originally used in Kirihara, Rokugo, Yonezawa, during the late Edo period and is designated as an Important Tangible Folk Cultural Property of Japan.
Visitors exploring cultural properties associated with the Uesugi family should also consider visiting Keishoden at nearby Uesugi Shrine.
Keishoden houses and displays armor, weapons, personal belongings, and other objects associated with figures such as Uesugi Kenshin and Uesugi Kagekatsu. Among the best-known objects associated with the Uesugi tradition is the helmet of Naoe Kanetsugu, a famous retainer of the Yonezawa Domain, featuring the distinctive character “愛” on its front crest.
The two facilities offer different approaches to Uesugi history. The Uesugi Museum focuses on historical documents, artworks, and cultural properties, while Keishoden allows visitors to explore the world of samurai through armor, weapons, and personal belongings. Visiting both provides a broader perspective on the Uesugi family and its history.
Matsugasaki Park, adjacent to Denko-no-Mori Yonezawa Uesugi Museum, was developed on the former site of Yonezawa Castle.
The park is home to Uesugi Shrine, which enshrines Uesugi Kenshin, as well as a bronze statue of Uesugi Yozan and various monuments connected with the Uesugi family.
After learning about the Uesugi family’s history and cultural heritage inside the museum, visitors can walk through Matsugasaki Park and explore the actual historic landscape associated with the clan. This combination makes it easier to visualize the history of Yonezawa Castle and the Uesugi family’s connection with the city.
Denko-no-Mori Yonezawa Uesugi Museum provides an excellent introduction to the history of the Uesugi family and Yonezawa through valuable cultural properties, including the National Treasures “Uesugi Rakuchu-Rakugai Screens” and the “Uesugi Family Documents.”
Visitors can learn about important figures ranging from Uesugi Kenshin during the Sengoku period to Uesugi Kagekatsu, who established the Uesugi family’s connection with Yonezawa, and Uesugi Yozan, who pursued major reforms of the Yonezawa Domain.
With Matsugasaki Park, Uesugi Shrine, and Keishoden all located nearby, the museum is also a convenient starting point for exploring Yonezawa’s historic sites. A visit offers travelers an opportunity to connect museum exhibits with the actual landscapes and places associated with the long history of the Uesugi family.
