  We report on our on-going effort to calculate the properties of light nuclei
directly from quarks and gluons based on lattice QCD. After briefly introducing
our motivations and aims, we describe our strategy of fixing the strange quark
mass at its physical value and approaching the physical point for the up and
down quark masses step by step from the region of heavy quark masses. A
successful calculation for the pion mass of 0.51GeV is reviewed, and the status
for a lighter pion mass of 0.30GeV is reported.
