We present potential detections of H-band scattered light emission around four young stars, selected from a total sample of 45 young stars observed with the Coronagraphic Imager with Adaptive Optics coronagraph of the Subaru telescope. Two Classical T Tauri stars, CI Tau and DI Cep, and two weak-lined T Tauri stars, LkCa 14 and RXJ 0338.3+1020, were detected. In all the four cases, the extended emission is within the area of the residual point-spread function halo, and is revealed only through careful data reduction. We compare the observed extended emission with simulations of the scattered light emission to evaluate the plausibility and nature of the detected emission.
