Reanalysis data necessary to climate modeling research are numerous available now. In this study, we checked the performance of river discharge simulation by using a regional climate model output produced with NCEP/NCAR (ds090.0), ERA-Interim and JRA25 reanalysis datasets in two decades, 1980s and 1990s. The Weather Research and Forecast model (ver. 3.2.1) was used in this study. The horizontal resolutions were 18km and 4.5km for outer and inner domains, respectively. The period of simulation is 20-year from Oct. 1980 to Oct. 2000. Five river basins (Agano River, Jinzu River Mogami River, Shinano River and Tone River) were selected to compare the observed and calculated river discharges.
