In this proceeding, we report the recent measurements of the CKM angle ϕ1(β) using large data samples collected by the Belle and BaBar experiments. The experiments have collected more than 1 billion B anti-B pairs of data sample at the Υ(4S) resonance using the facilities of the asymmetric-energy e+e- colliders KEKB and PEP-II.
