      abstract     = {We present two recent measurements of semileptonic B decays
                      at Belle, offering valuable insights into the determination
                      of the Cabibbo-Kobayashi-Maskawa (CKM) matrix element
                      $|V_{ub}|$. These analyses use the full Belle dataset,
                      comprising $772 \times 10^6$ $B\bar{B}$ pairs collected at
                      the $\Upsilon(4S)$ resonance. With an innovative strategy,
                      the inclusive $B \to X_u \ell \nu$ and exclusive $B \to \pi
                      \ell \nu$ decays are simultaneously analyzed for the first
                      time, and the $|V_{ub}|$ ratio is extracted as
                      $|V_{ub}^{\mathrm{excl.}}|/|V_{ub}^{\mathrm {incl.}}|=0.97
                      \pm 0.12$. Furthermore, we provide preliminary results for
                      the inclusive branching fractions ratio of $B \to X_u \ell
                      \nu$ and $B \to X_c \ell \nu$ decays, accompanied by
                      additional interpretations aimed at deriving the inclusive
                      $|V_{ub}|/|V_{cb}|$ ratio.},
