Plain Language Summary: An overview of the newly developed operational seasonal forecasting system JMA/MRI-CPS3 is presented. Improvements in forecast initialization methods, model resolution, and physical processes have resulted in superior forecast performance over the previous system on sub-seasonal to seasonal time scales. To enhance its application to shorter forecast lead times, the operational schedule was modified to update forecasts on a daily basis.
