Abstract
I review the recent progress in lattice QCD, which will be useful in heavy quark physics in the near future. Reviewing the theoretical developments in lattice QCD first, I focus our recent unquenched QCD with dynamical overlap fermion as implemented by JLQCD collaboration. I also introduce some of our recent studies on the B^*B\pi coupling and on the determination of |V_{ub}| through the dispersive bound.
