The 'udatsu' walls were originally built as fire-prevention barriers between wooden townhouses, but evolved into status symbols indicating a merchant's wealth.
The town served as a mandatory stop for the Matsudaira clan and other daimyo processions traveling to Edo.
Remnants of the town's medieval fortifications are still visible in the defensive layout of the street corners.

Unno-juku is a remarkably preserved post town located on the historic Hokkoku Kaido road, which served as a vital route connecting the Nakasendo and Zenko-ji temple. The town retains its medieval atmosphere through a dense concentration of Edo-period structures, including traditional machiya townhouses with lattice work and udatsu decorative firewalls. The site is anchored by the Shiratori Shrine, a medieval foundation featuring distinctive architecture and ancient cedar trees. Unlike many modernized historic districts, Unno-juku maintains an authentic residential character with functional irrigation canals running along the street edges. The town gained prominence during the Edo period as a stop for high-ranking officials and travelers on their way to the coast of the Sea of Japan. Much of the original urban layout and building facade patterns from the 17th to 19th centuries remain intact today. It serves as a rare example of a Japanese post town that survived rapid industrialization.
