This study aimed to analyze the primary factors affecting the actual intake water of agricultural water use from water facility. The study was conducted on 19 locations of water user association called Land Improvement District (LID) which were operated under traditional water right in Kyushu Island, Japan during irrigation period of 1997. Quantitative analysis I, developed by Hayashi, was applied for the analyses. The explanatory variables consisted of 6 items and 18 categories. Each explanatory variable (item and category) was given as dummy variable such as 1 or zero. Results showed that the intake water was affected by the location of beneficiary area, the intake water for another purposes and the size of beneficiary area. The intake water varied to the concerning LID. The observed intake water ranged from 26.10 mm/day to 212.10 mm/day and the predicted intake water ranged from 24.53 mm/day to 210.53 mm/day (Case 1, r=0.96). The obtained results were reasonable to explain the characteristics of the factors affecting the actual intake water of agricultural water use in those areas
