We measure the branching fractions of B0?J/??(') decays with the complete Belle data sample of 772×106 BB¯ events collected at the ?(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. The results for the branching fractions are: B(B0?J/??)=(12.3±1.71.8±0.7)×10-6 and B(B0?J/??')
