Tsujun Bridge

Built in 1854 to solve water shortages in the terraced rice fields, this stone arch aqueduct bridge is one of the largest of its kind in Japan, with an aqueduct length of Approx. 119 m, a height of Approx. 21.3 m, and a bridge length of Approx. 78 m. It was designated an Important Cultural Property of Japan in 1960, and in 2023 it became the first civil engineering structure in the country to be designated a National Treasure.

Inside the bridge is a mechanism that draws up water through three stone water pipes, applying the principle of the siphon. It is still in active use today, sending 15,000 cubic meters of water in 24 hours and continuing to irrigate the terraced rice fields.

Water is released Approx. 120 times a year, and visitors can watch the powerful streams burst from both sides of the bridge from the surrounding embankments up close. By paying the crossing fee, it is also possible to watch from the top of the bridge. The schedule for release days is updated regularly on the official website.
