The Uesugi Museum holds clan documents, armour, and historical material that help make sense of the shrine and castle ruins next door. It is the place to go if the names Uesugi Kenshin and Date Masamune are more than passing curiosities.
The permanent displays are compact, and special exhibitions change through the year. Pair it with Uesugi Shrine for a fuller picture of why this small town mattered.
