We performed the optical and near-infrared photometric observations of V5587 Sgr (Nova Sgr 2011) since Feb. 3. The light curves exhibit the rebrightening by 0.6 mag during a week. This nova has already undergone the rebrightening three times until this. The first one had a longer timescale of 30 days with the amplitude of 0.5 mag than other two ones. Other two ones show rather shorter timescale within 10 days and sharp variations. This phenomena may be similar to be oscillation seen in O-class novae (e.g., V603 Aql), whose classification is suggested by Strope et al. 2010.
