We observed the optical afterglow of the bright gamma-ray burst GRB 030329 on the night of 2003 March 29 using the Kiso Observatory (University of Tokyo) 1.05 m Schmidt telescope. Data were taken from March 29 13:21:26-17:43:16 UT (0.072-0.253 days after the burst) using an R_C-band filter. The obtained R_C-band light curve has been fitted successfully by a single-power-law function with a decay index of 0.891±0.004. These results remain unchanged when incorporating two early photometric data points at 0.065 and 0.073 days, reported by Price et al. using the Siding Spring Observatory 40 inch (1.0 m) telescope, and when also including data from the Russian-Turkish 1.5 m Telescope (Burenin et al.) covering about 0.3 days. Over the period of 0.065-0.285 days after the burst, any deviation from the power-law decay is smaller than ±0.007 mag. The temporal structure reported by Uemura et al. does not show up in our R-band light curve.
