The collection originated from the 'Sanada House Treasure,' which was donated to the city of Nagano by the 12th head of the Sanada family in 1966.
The archives include the 'Sanada-ke Bunsho,' a vast collection of documents providing a detailed look at administrative life in the Edo period.
The museum serves as the primary repository for the Aoyagi and Sanada family heirlooms.
The site acts as a research center for scholars specializing in the Sengoku period's transition to the relative stability of the Edo era.
The Sanada Treasure Hall preserves the personal archives and artifacts of the Sanada clan, who governed the Matsushiro Domain during the Edo period. The collection features over 50,000 items, including armor, swords, calligraphy, and historical documents once held by the Sanada lords. Key highlights include the 'Seirai-ki' record and various weapons used during the Sengoku and Edo eras. The museum structure was built to commemorate the 400th anniversary of the clan's entry into Matsushiro. The facility is situated within the historic Matsushiro castle town district. Exhibits are rotated regularly to display different aspects of the clan's cultural and military history.
