Plain Language Summary: The Himawari-8 Rainfall estimation Algorithm (HRA) was developed by using the Random Forest (RF) machine-learning method. Training data is obtained from an Infrared (IR) radiometer of a third-generation geostationary meteorological satellite (GEO), Himawari-8, and Ku-band precipitation radar on board the Global Precipitation Measurement (GPM) core observatory. HRA could estimate heavy rainfall from warm-type precipitating clouds in Kanto-Tohoku heavy rainfall events although the Global Satellite Mapping of Precipitation (GSMaP_NRT) could not estimate such heavy rainfall when microwave satellites were unavailable.
