The Denkoku-no-Mori Yonezawa City Uesugi Museum is a museum adjacent to Matsugasaki Park which is also the site of the honmaru (inner citadel) of Yonezawa Castle. It holds valuable articles relating to the Uesugi Clan that flourished as warriors.
The highlight of the museum is without doubt the Uesugi Rakuchu Rakugai Zubyobu (Folding Screen) national treasure. It is said that this folding screen that depicts everyday life in Kyoto was sent by Oda Nobunaga to Uesugi Kenshin. It depicts approximately 2,500 people regardless of their social status. Furthermore, you can understand what it was like to be in Kyoto in those days because it also depicts animals, plants, famous places and festivals. Usually, a replica is on display. However, the original is exhibited for a limited time in the spring and fall when a special exhibition is held.
In addition to this, there is an exhibition that looks back at the achievements of Uesugi Yozan - the ninth feudal lord of the Yonezawa Domain who left behind the wise saying of, ""Everything that can be done must be done."" You can learn about the history of the Uesugi Clan and the culture of Yonezawa. There is a museum shop that sells original goods of Uesugi Kenshin, Uesugi Yozan and Naoe Kanetsugu. There are also items you can only purchase here.
The adjacent Matsugasaki Park is home to Uesugi Shrine where Uesugi Kenshin is enshrined and many monuments relating to the Uesugi Clan (e.g., a bronze statue of Uesugi Yozan). Please make sure to stop by when exploring the park.
