Uesugi Clan Archives

The Uesugi Clan Archives is a collection of documents and manuscripts spanning several centuries, housed in the Yonezawa City Uesugi Museum. The records date from the Kamakura and Edo periods and include administrative papers, correspondence, and daily notes that document how the clan operated.

The archives were designated a National Treasure in 2001 and preserve records from when a major samurai clan controlled an entire region in northern Japan. These documents show how administration evolved over hundreds of years and reflect the clan's response to changing circumstances.

The collection shows how the Uesugi family governed their lands and interacted with neighboring clans through everyday documents and official records. These papers reveal the practical ways people organized their communities and made decisions during feudal times.

You can view the documents at the Uesugi Museum in Yonezawa, which is accessible from the city center. It helps to check ahead which parts of the collection are on display, since the materials are often rotated and not everything is shown at once.

Many of the original manuscripts were donated to the museum by Takanori Uesugi and provide deep insights into how a single family shaped northern Japan's regional development. These personal materials reveal the practical strategies the clan used to maintain power and influence across generations.
