We present a measurement of the Cabibbo-Kobayashi-Maskawa matrix element data collected by the Belle detector at the KEKB e+e-asymmetric collider. Events are tagged by fully reconstructing one of the B mesons, produced in pairs from Υ(4S). The signal for b→u semileptonic decay is distinguished from the b→c background using the hadronic mass MX, the leptonic invariant mass squared q2 and the variable P+≡EX-|p→X|. The results are obtained for events with pℓ*≥1GeV/c, in three kinematic regions (1)MX<1.7GeV/c2, (2)MX<1.7GeV/c2 combined with q2>8GeV2/c2, and by (3)P+<0.66GeV/c. The matrix element |Vub| is found to be (4.09±0. 19±0.20-0.15+0.14±0.18)×10-3, where the errors are statistical, systematic including Monte Carlo modeling, theoretical, and from shape function parameter determination, respectively.
