Every April,residents clear the waterways together.
Every year in early April, the Joshiki: waterways are cleared of silt all at once, from riverbeds to irrigation channels. The Ministry of the Environment calls it unique to Tsuru, with some 9,000 residents joining in each year. In 2026 it was held on 5 April, when sediment was removed from the city’s waterways.
