The Calorimetric Electron Telescope (CALET) is conducting direct measurements of high-energy cosmic rays up to ~1 PeV to achieve a systematic understanding of cosmic ray acceleration and propagation. The detector, which consists 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 are transferred to JAXA and immediately forwarded to the Waseda CALET Operations Center. Data acquisition began in October 2015 and has continued stably without any major issues. We have collected data for 10 years so far. We summarize the detector operation for the 10-year observation. We also report the detector calibration based on the time-dependent corrections.
