Promoting labor saving for water management during rice cultivation by utilizing information and communication technology (ICT) is stated as one of the government policies, including “Basic plan for food, agriculture and rural areas”. Studies have not been sufficiently conducted to develop a device to attain the water management system utilizing ICT, and verify the effects on the contribution of this device to labor-saving. In this study, a water management using auto-irrigating devices operating with personal digital assistance, was compared with the conventional water management by using simplified GPS trackers fitted on farmer's cars. In the case of using auto-irrigating devices, the operating time per device and area were reducing by 27% and 41%, respectively. In the case of conducting the water management in an intensified area, the reduction of operating time of valve manipulation can be thought to have a profound effect because the percentage of the operating time of valve manipulation is approximately half of the total whole water management time, including the transfer.
