The Yoshinaka Museum, established in 1992, is dedicated to preserving the legacy of Kiso Yoshinaka and Tomoe Gozen, pivotal historical figures from the Kiso region. Following nearly three decades of enriching local and cultural heritage, the museum underwent a significant renovation and reopened in 2021. This transformation aims to enhance community engagement and deepen pride in local history.

At the heart of the museum’s offerings is the concept of "Letters from Yoshinaka and Tomoe," featuring a diverse array of exhibits such as paintings, videos, sculptures, and interactive artworks, all crafted by various artists. These unique displays invite both newcomers and those familiar with Yoshinaka and Tomoe to explore their enigmatic lives and the daily scenes of Kiso Town. The museum also houses a library filled with resources about these historical figures, complemented by internet access for further research.

Visitors to the Yoshinaka Museum can look forward to not only an enriching experience but also the opportunity to explore the many sites related to Yoshinaka in and around Kiso Town.
