About this spot
Tsujun Bridge in Yamato, Kumamoto Prefecture, is one of Japan's largest stone arch aqueduct bridges, built in 1854 at the end of the Edo period. Constructed to carry water to the water-starved Shiraito Plateau, it is a precious heritage that conveys the advanced stone construction techniques of its time, and in 2023 it became the first civil engineering structure designated a National Treasure. The main highlight is the "water discharge," in which water shoots out forcefully from the discharge ports at the center of the bridge. Originally a maintenance function to flush out mud that collects in the channel, this dynamic spectacle has become a sightseeing highlight that captivates many visitors. On discharge days you can also walk across the top of the bridge, where the peaceful countryside seen from a height of about 20 meters is simply spectacular. At the adjacent Michi-no-Eki Tsujunkyo roadside station, you can enjoy fresh local vegetables, regional specialties, and local cuisine. Come and experience up close this magnificent structure that embodies history, nature, and ingenuity.
