Abstract. Recent
results on CP-violation measurements in $B$ decays
from energy-asymmetric $B$-factory
experiments are reported.
Thanks to large accumulated data samples, CP-violations in
$B$ decays in mixing-decay interference and direct
CP-violation
are now firmly established. The measurements of three angles of the
unitarity triangle from
CP-violations of $B$ decays are quite consistent with the
Standard
Model expectations. These results
strongly support the validity of the
Kobayashi--Maskawa
prescription of CP-violation.
Keywords. CP-violation; $B$ decays; flavor
physics.
