The measure of {ital CP} violation {ital J} in the Kobayashi-Maskawa (KM) model is estimated by expansion around {vert bar}{ital V}{sub {ital u}{ital b}}{vert bar}=0. We obtain that {vert bar}{ital J}{vert bar}{congruent}{vert bar}{ital V}{sub {ital u}{ital s}}{vert bar}{vert bar}{ital V}{sub {ital c}{ital b}}{vert bar}{vert bar}{ital V}{sub {ital u}{ital b}}{vert bar} and the KM asymmetry parameter {omega}{congruent}{minus}{vert bar}{ital V}{sub {ital u}{ital s}}{vert bar}{sup 2}{vert bar}{ital V}{sub {ital c}{ital b}}{vert bar}{sup 2}. We discuss the implication of imposing this condition on the KM matrix elements, on the top-quark mass using the measurements of {var epsilon}{sub {ital K}}, {ital B}{sub {ital d}}{sup 0}-{ital {bar B}}{sub {ital d}}{sup 0} mixing, {vert bar}{ital V}{sub {ital c}{ital b}}{vert bar}, and {vert bar}{ital V}{sub {ital u}{ital b}}{vert bar}/{vert bar}{ital V}{sub {ital c}{ital b}}{vert bar}. A comparison with the symmetric KM matrix is made.
