We update the light curve of Type II SN 2009js. We confirmed the broadly brightening in I-band light curve, comparing with those of other bands. Since the rapid decline of the luminosity in bluer bands is not seen, we suggest that the brightening luminosity in I-band would not be caused by contributions from the near-infrared radiations of low temperature due to forming the dust in the SN ejecta. But, the B-band luminosity may be affected. In order to clarify the origins of the brightening in the I-band, we encourage the photometric observations in the near-infrared wavelength.
