We developed Aerogel RICH (ARICH) detector as a forward endcap PID detector in the Belle II spectrometer. ARICH consists of 248 aerogel tiles as radiators and 420 Hybrid Avalanche Photodetectors (HAPDs) as photon detectors. Belle II conducted the commissioning operation in 2018, and then started the physics run this year. In this presentation, the operation and experience as well as the initial performance of the ARICH detector is reported.
