Tsujunkyo Bridge is Japan’s largest stone-arch aqueduct bridge and is used to pump water into the region’s rice paddies. A giant stone bridge, built in 1854, that releases over 15,000 square meters of water from it’s sides, Tsujunkyo is active every weekend and holiday from late spring to late fall (approximately May to November). The impressive discharge of water lasts about 20-25 minutes.
Although the bridge itself is currently closed to tourists because of ongoing assessment of damage after the Kumamoto Earthquake, the discharge of water can still be viewed.
