Tsujunkyo Bridge 通潤橋 - Yamato

Kumamoto's unique aqueduct

Tsujunkyo Bridge is one of Kumamoto’s lesser known treasures. Built in 1854 it is not only Japan’s largest stone aqueduct but also it’s most unusual due to it’s dramatic water release designed to remove silt from the water channels. On certain days it’s also possible to walk on top of the bridge and watch the water release close up.

Tsujunkyo bridge background

Tsujun Bridge is located in the rural town of Yamato on the outer southern edge of the Aso caldera. Built to carry water to irrigate the difficult to reach rice fields of the Shiraito plain. After several years of repairs due to damage from the Kumamoto earthquakes of 2016 and torrential rain of 2018, the bridge is now back in full working order and has recently been designated a national treasure.
