The lepton mixing angle theta_13, the only unknown angle in the standard three-flavor neutrino mixing scheme, is finally measured by the recent accelerator and reactor neutrino experiments. We perform a combined analysis of the data coming from T2K, MINOS and Double Chooz experiments and find that theta_13 = 0 is rejected at a significance level higher than 3.5 sigma CL. We also discuss the near future expectation on the precision of the theta_13 determination by using expected data from these ongoing experiments as well as another reactor experiment RENO.
