Kiso no Kakehashi

Kiso no Kakehashi was once considered one of the three most difficult passages along the Nakasendo Road, alongside the Ota Ferry Crossing and Usui Pass, as reflected in the old saying: "If only Kiso no Kakehashi, the Ota Ferry Crossing, and Usui Pass did not exist."
It is also counted as "Asagiri no San" (Morning Mist at the Shore), one of the Eight Views of Kiso Hakkei, and is widely known as a verse in the "Kisobushi" folk song and the Nagano Prefecture anthem, "Shinano Province."
In 2016, it was certified as a "Japan Heritage" by the Agency for Cultural Affairs.
Kiso no Kakehashi is not a bridge spanning to the opposite bank, but a walkway built horizontally parallel to the cliff.
At the time, it was a simple bridge made of logs as pillars and planks laid sideways.
However, in 1647, a passerby dropped a torch and it burned down.
Therefore, by order of Bishu Domain, a stone wall measuring 102m in length, 6.7m in width, and 13m in height was constructed, and a 14.5m bridge was built across the center.
(Later, the bridge section was also made into a stone wall.)
It is now designated a Nagano Prefecture historic site, and part of the stone wall remains preserved beneath the national highway, remaining a vestige of its former glory.

Furthermore, as exemplified by Basho Matsuo's poem "The vines that entangle life on the fence" (Sarashina Travelogue), many literary figures composed poems about it.
Currently, stone monuments to Basho Matsuo, Shiki Masaoka, and Santoka Taneda stand near the inn.
