We search for the process B0→π-τ+ντ using the full Belle data set of 711 fb-1, corresponding to 772×106BB¯ pairs, collected at the (4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. We reconstruct one B meson in a hadronic decay and search for the B0→π-τ+ντ process in the remainder of the event. No significant signal is observed and an upper limit of B(B0→π-τ+ντ)<2.5×10-4 is obtained at the 90% confidence level.
