After its construction during 2009 to 2013, the first CW beams of 20 MeV were successfully transported through the recirculation loop in February 2014*. Since then, various accelerator studies have been carried out. We have so far succeeded in recirculating CW beams of 30 uA through the loop with very-small beam losses. Initial emittance measurements were carried out in the recirculation loop. We also carried out commissioning of a X-ray source using the laser Compton scattering**. During these studies, both a photocathode DC electron gun and superconducting cryomodules have been worked very stably. We present our results of cERL commissioning, measured beam properties, operational status, and future prospect.
