Description
We present an inclusive study on the measurement of the branching fraction of the radiative B meson decay B \to X_s \gamma, using the full data sample collected with the Belle detector at the KEKB asymmetric-energy e^{+}e^{-} collider, corresponding to 753\times10^6$ B\bar{B} pairs. One of the B mesons in the \Upsilon(4S) \to B\bar{B} decay is fully reconstructed in hadronic modes, and the radiative photon is sought in the decay of the other B meson. We plan to obtain the CP asymmetry and the isospin asymmetry according to the measured photon energy spectrum.
