  The nearly right unitarity triangle can be simply obtained if a quark mass
matrix is written as a linear combination of real rank-1 matrices and the
coefficient which gives the mass of the second generation is pure imaginary.
Supposing that the source of the CP violation is in the Yukawa coupling to an
additional Higgs field which provides a factor for the strange quark and muon
mass ratio, we obtain that the angle $\alpha= \phi_2$ of the unitarity triangle
shifts from $90^{\rm o}$ by units of $V_{ub}/V_{us}$, and is postdicted as
$\alpha \simeq 87^{\rm o}$ or $91^{\rm o}$. The Dirac CP phase $\delta$ which
appears in the three-flavor neutrino oscillations is obtained to be $|\delta|
\simeq 80^{\rm o}$ if the neutrino mass matrix gives tri-bimaximal-like mixing
form. If the factor 3 for the muon and strange quark mass is considered in a
simple manner in the quark-lepton unification, we obtain three distinctive
prediction of $\delta$ for nearly right-angled phase as $|\delta| \simeq
70^{\rm o}$, $90^{\rm o}$, or $110^{\rm o}$ in an idealistic orthogonal
structure of the neutrino mass matrix. The deviation from $90^{\rm o}$ is
roughly given by $\arcsin(1/3)$ by inputting the experimental measurements.
