Summary

This survey attempts to grasp the actual circumstances of irrigated paddies and cistern water used in irrigation at groundwater recharges in Nanao Hill and the Tama River and Asakawa River basins in the earty 21st century in the City of Hino,Tokyo from a humanities perspective,as well as to RAISE future issues aimed toward conservation and utilization.

In this research, we first collected and organized literature and data from Hino City Hall and libraries on previous research conducted on irrigated paddies in the city of Hino as part of preliminary research into the actual circumstances.

Next, we went to around 40 planted paddies around the city of Hino to verify location and,to the extent possible, conducted interviews with paddy owners.

Then, we created a ground plan of 28 of the 40 planted paddies using levels and rangefinders and measured the elevation of major points. At the same time, we observed and recorded methods and routes for bringing irrigation water in from cisterns.

We created an individual file for each paddy with attached research records including Photographs, ground plans and cross-sectionals showing elevation, and irrigation water routes based on the data obtained during these field surveys.

We also created individual files with sketches and photographic material for the paddies we were unable to survey due to time restrictions.

We then compiled these individual files into the “Register of lrrigated Paddies in Hino".

Doing so has made it possible to understand the location environment and water routes of all remaining irrigated paddies within the city.
