Abstract To investigate water resources problem under climate change condition, one of the main river basin in Japan, the Tone River basin was modeled and simulated. The Tone River is the main water source to the metropolitan Tokyo, Japan, and upstream of the basin is in snow-dominated regions. Future climate condition was set by output of a super high-resolution atmospheric model (AGCM20) that was developed by the Japan Meteorological Agency (JMA) and the Meteorological Research Institute (MRI), Japan. Evaluation for the future water resources condition in this study considering reservoir operation shows that reproducing current dam release pattern is able to realize even with the shifted snowmelt inflow under the future climate condition. In this case, the water level regulations should be revised, and the shortage of the reservoir water in summer season should be carefully considered. At the outlet of the study basin, Kurihashi station, effects of the controlled water release from the dam reservoirs was negligible, and the shifted snowmelt effect was also not severe and therefore the future water resources condition at the station may not be very different to the current condition.
