After the inspiraling phase in a binary coalescence, black hole formation and emission of ringdown gravitational waves are expected. Their waveforms are well expressed by quasi-normal modes of black holes. To search for such signals in TAMA300 data, matched filtering technique is implementated. We employ a new template construction method for ringdown filters recently proposed by Nakano. With a Monte-Carlo study by injecting ringdown waveforms into TAMA300 data, we examine detection efficiency of our method and detection probability for Galactic ringdown events. We also discuss vetoing techniques for spurious event reduction.
