In this paper, we present preliminary measurements of |Vub| from exclusive semileptonic decay B0 → π- ℓ+ νℓ and hadronic decay B0 → Ds+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+ → ωℓ+ νℓ) and upper limits on B+ → ℓ+ νℓ (ℓ = e, μ).
