Yamato, Kumamoto (熊本県山都町) – Tsujun Bridge (通潤橋 – Tsūjun-kyō) water discharge 2025 Nov. 29
Sujimbashi Bridge in Yamato Kumamoto. You can see there’s water coming out on two uh holes from each side. And you can see people over here. So, they release this about twice a day, most days of the week, one and 3:00 I I believe. But anyways, check your time. Huh? I just put it on. Get enough. So, we’re from a slightly lower vantage point. The first 15 minutes is when the water is most prolific. Sujun Bridge.
We arrived just in time to see the water discharge from Tsujun Bridge (通潤橋 – Tsūjun-kyō in Japanese), a stone arch bridge and a Japan-designated “National Treasure” (国宝) that was built in 1854. This engineering marvel is not only Japan’s largest stone aqueduct but also its most unusual due to its dramatic water release designed to remove silt from the water channels. The structural purpose was to supply water to the Shiraito Plateau where farmers and residents suffered from water shortage at that time.
The water release takes place on from April to November from 1PM for 15 minutes. As you can see from the clip, a giant spray of water gushes out from each side of the bridge, although the discharge is at its peak for about the first 10 minutes. In general you can see the water release from Thursday to Sunday, on public holidays and sometimes on Wednesdays. Make sure to check their site for the planned discharge dates and times.
