The purpose of this study is to develop the new calculating method for water supply demands in the restaurants. In this paper, the measurements of water consumption were carried out in the 21 restaurants and the basic data about the store characteristics were obtained from the management company. First, the relationship between store characteristics and number of customers was analyzed. From the result of the Hayashi's Quantification Theory Cluster III, the restaurants were classified by three main explanatory axes related to store characteristics. Next, the water consumptions were analyzed by using the measurement data in each restaurant. As a unit requirement, the daily water consumption per store area and the daily water consumption per customer were calculated. Finally, by using the multiple regression analysis, it was obtained that the prediction formula for unit requirement of daily water consumption adapted two explanatory variables concerned with three explanatory axes showed by the Hayashi's Quantification Theory Cluster III
