The Calorimetric Electron Telescope (CALET) is carrying out direct measurements of high energy cosmic rays up to ~1 PeV in order to obtain systematic understanding of cosmic ray acceleration and propagation. The detector consisting of a charge detector, an imaging calorimeter, and a total absorption calorimeter, is located on the International Space Station. Data taken by the CALET onboard the International Space Station is transferred to JAXA and is immediately send to Waseda CALET Operations Center. Data taking started in October 2015 and continues stably without any serious troubles. We have taken data for 10 years so far. We report the summary of the detector operation for 10 years observation. Also, we report the detector calibration based on the time-dependent correction.
