We present the performances of direct imaging with adaptive optics, coronagraph, and imaging-polarimetry of the coronagraphic imager with adaptive optics (CIAO) for the Subaru telescope. Combining with the 36-element adaptive optics system, CIAO produces high-resolution images with a full width at half maximum of ${0\rlap {.}{}^{\rm {\prime \prime }}072}$ and a Strehl ratio of 0.28 in the $K$ band...
