Overview of flavor physics results at Belle

We will present recent topics of the flavor physics in decays of the heavy mesons at the Belle experiment. Most of the results are based on a full data set which corresponds to 772 million BB̄ pairs collected at the ϒ(4S) resonance with the Belle detector at the KEKB asymmetric energy e+e− collider. We also discuss about prospects of the studies in the future B-factory experiment
