Yamato, Kumamoto / 通潤橋
Tsujun Bridge
One of Japan's largest stone arch aqueduct bridges, built in 1854 (Kaei 7) by Futa Yasunosuke, a village headman of Yabe, to carry water to the Shiraito plateau, which suffered from water shortages. It is the only stone arch bridge that can "discharge water", about 78 m long and 21.3 m high, and still waters the terraced rice fields of the plateau. In 2023 it became the first civil-engineering structure in Japan to be designated a National Treasure; its water discharges, about 120 a year, can be seen up close.
