Research on Irrigation custom and the order of villages

我研究了长野泽市灌区的灌溉风俗“大田原”。长野泽基是一条运河，灌溉着高崎市的许多水田。Otaharai是旱灾发生时向下游村庄分发灌溉水的习俗。下游村民临时冲毁上游堤坝，取灌溉用水，直到上游村子修好了堤坝。至少在长野泽市的四条支渠中都有小田原的习俗。它的基础是在严重干旱期间均匀分配灌溉水的原则。上游村落与下游村落的关系各不相同。一些人是敌对的，另一些人是友好的。它们是由大量的水和历史细节造成的。

I researrched the irrigation custom called "Otaharai" in Naganozeki irrigation area. Naganozeki is the canal, irrigating many paddy fields in Takasaki city. Otaharai was the custom to distribute irrigation water to the lower reaches villages at the time of the drought. People of the lower reaches temporarily broke dams of the upper reaches, and got irrigation water until the dams repaired by people of the upper reaches village. Otaharai custom were being practiced in four branch canals of Naganozeki at least. It was based on the principle of equal distribution of irrigation water during the critical drought. Relations between the upper reaches villages and the lower reaches villages varied. Some were antagonistic and the others were friendly. They were caused by amounts of water and historical details.
