  We present charm CP violation and mixing measurements at Belle. They are the
first observation of $D^0-\bar{D}^0$ mixing in $e^+e^-$ collisions from
$D^0\rightarrow K^+\pi^-$ decays, the most precise mixing and indirect CP
violation parameters from $D^0\rightarrow K^0_S\pi^+\pi^-$ decays, and the
time-integrated CP asymmetries in $D^0\rightarrow\pi^0\pi^0$ and
$D^0\rightarrow K^0_S\pi^0$ decays. Our mixing measurement in $D^0\rightarrow
K^+\pi^-$ decays excludes the no-mixing hypothesis at the 5.1 standard
deviation level. The mixing parameters
$x=(0.56\pm0.19^{+0.03+0.06}_{-0.09-0.09})%$,
$y=(0.30\pm0.15^{+0.04+0.03}_{-0.05-0.06})%$ and indirect CP violation
parameters $|q/p|=(0.90^{+0.16+0.05+0.06}_{-0.15-0.04-0.05})$,
arg$(q/p)=(-6\pm11\pm3^{+3}_{-4})^{\circ}$ measured from $D^0\rightarrow
K^0_S\pi^+\pi^-$ decays, and the time-integrated CP asymmetries
$A^{D^0\rightarrow\pi^0\pi^0}_{CP}=(-0.03\pm0.64\pm0.10)%$ and
$A^{D^0\rightarrow K^0_S\pi^0}_{CP}=(-0.21\pm0.16\pm0.07)%$ are the most
precise measurements to date. Our measurements here are consistent with
predictions of the standard model.
