Matsumoto City Museum, City history and folk museum in Ōte, Matsumoto, Japan

Matsumoto City Museum is a history and folk museum in Ōte, Matsumoto, holding about 100,000 objects related to Matsumoto Castle and donated by citizens. It opened in a new building in October 2023, with permanent exhibits on the third floor arranged around eight themes such as "a castle town" and "a bustling commercial city."

The museum's predecessor, the Meiji 37-38 War Memorial Hall, opened on 21 September 1906 inside the old Kaichi School building. Renamed Matsumoto Memorial Hall, it passed to city control on 1 June 1931, moved to Matsumoto Castle's ninomaru in 1937, and became Matsumoto City Museum in 1948. Registered under the Museum Act in 1952, it reopened in a new building in Ōte on 7 October 2023.

The permanent exhibition is organised into eight themes, among them "a castle town", "a bustling commercial city" and "mountains we live with", and works as an index to the whole of Matsumoto, pointing visitors to sites elsewhere in the city. The museum also holds folk materials donated by residents, including a collection of 45 Tanabata dolls and 293 items of folk religion.

The location is near Matsumoto Castle and accessible on foot from the town center. Plan time to walk through the galleries and explore the different exhibition spaces at a comfortable pace.

The museum's collection includes the Peacock-patterned kei, a Buddhist percussion instrument designated an Important Cultural Property, along with roughly 100,000 objects, among them a 45-piece Tanabata doll collection and 79 farming tools. Many were donated by citizens of Matsumoto.
