The Sayabashi Bridge is a bridge over the Kanakura River in Kotohira-cho, Kagawa Prefecture. This arched wooden bridge with copper roof in Kara-hafu style (undulating bargeboards) is said to have been constructed during the Genroku era (1688-1703). The deck of this bridge is 4.2 m above the water and 24 m in length.

It was named Sayabashi (Scabbard Bridge) because its curved shape is similar to the scabbard of a sword. It is also known as the “Uki Bashi (Floating Bridge)” because it no bridge legs. It was registered as a Registered Tangible Cultural Property in 1998.

The bridge had been washed away by floods several times and removed to the present place in the Meiji period (1868-1912). Since then, it is opened only once a year for the Otaisai festival of Kotohira-gu Shrine in October every year.
