I describe the recent measurement of the CP violating parameter $\sin 2 \phi_1 =(0.99\pm 0.14\pm 0.05)$ from the Belle experiment at KEK.
We present a measurement of the time-dependent $CP$ asymmetry in $B^0 \to K_{\rm S}^0 \: \pi^{+} \pi^{-} \gamma$ decays using a data set of 365 fb$^{-1}$ recorded by the Belle II experiment and the final data set of 711 fb$^{-1}$ recorded…
We present a measurement of CP-violating asymmetries in B0 -> pi+pi- decays based on 41.8 fb-1 data sample collected at the Y(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. From the asymmetry in the…
We report the first measurement of CP-violation parameters in $B^0\to\rho^0\gamma$ decays based on a data sample of $657\times 10^6 B\bar{B}$ pairs collected with the Belle detector at the KEKB asymmetric-energy $e^+ e^-$ collider. The…

In this report we summarize the most recent results of measurements of the angle $\gamma/\phi_3$ of the Unitarity Triangle.
The Belle experiment has measured branching fractions and CP asymmetries for the charmless decays B0->pi+pi- and B0->rho+-pi-+. From these measurements, constraints upon the CKM angle phi_2 can be obtained. These constraints indicate that…

We report on $CP$ violation measurements at Belle and Belle II, focusing on improving the precision of observables sensitive to the Cabbibo-Kobayashi-Maskawa matrix parameters. We present recent measurements of the CKM unitarity angle…
I will review the latest developments in determining the CP-violating phases of the CKM matrix elements from measurements by the BaBar and BELLE experiments at the high-luminosity B factories (PEP-II and KEKB). The emphasis will be on the…

The Belle II collaboration operates a substantially upgraded Belle detector at the SuperKEKB energy-asymmetric e+ e- collider. Belle II will start recording collisions at the Upsilon(4S) energy in 2018, aiming to collect by 2025 50 ab^{-1}…
