✦ Synopsis

In this paper, we present preliminary measurements of |V ub | from exclusive semileptonic decay B 0 → π -+ ν and hadronic decay B 0 → D + s π -using data sample of asymmetric e + e -collision recorded at Υ(4S) resonance with Belle detector at KEKB collider. Also presented are preliminary measurement of B(B + → ω + ν ) and upper limits on B + → + ν ( = e, µ).
