Going beyond Inume-shuku, there is another post station that retains the atmosphere of the olden days. Shimorotisawa-shuku functioned jointly with the next station, Kamitorisawa-shuku. Kamitorisawa-shuku opened from the 1st to 15th of the month, and Shiromotorisawa-shuku opened from the 15th to the last day of the month. A short way from Kamitorisawa-shuku is Saruhashi Bridge. It is one of the three unique bridges in Japan. Well known as a scenic beauty from the olden days, its rare structure is supported by four-layered posts stretching out from both sides of the cliff, and it has no piers. It is featured in “A Painting of the Koyo Saruhashi Bridge” by Utagawa Hiroshige. Saruhashi-shuku is on the other side of Saruhashi Bridge. The landscape created by Saruhashi Bridge and the Katsura River are a treat for travelers passing along the road. Visitors enjoy the landscape along the walking path leading from Saruhashi Bridge. The Otsuki City Local Museum also shows the structure of Saruhashi Bridge, and the circumstances of post stations in the olden days.
