We report the measurements of $CP$ violation in $B$ meson decays focusing on the recent studies obtained using a data sample of 772 million $B\bar{B}$ collected by the Belle detector running at the $\Upsilon (4S)$ resonance at the KEKB $e^+ e^-$ collider. We measure the $\phi_1$ and $\phi_2$, that are angles of the unitary triangle of Cabibbo-Kobayashi-Maskawa (CKM) matrix. Obtained results are consistent with expectations from the Standard Model (SM). Further studies using more statistics in the upgraded $B$-factory experiment are needed for more precise verification and search for the contribution from the new physics.
