Abstract
The Belle and Belle$~$II experiments have collected a 1.1 ab$^{-1}$ sample of collisions at the $\Upsilon(4S)$ resonance. These data, with low particle multiplicity and constrained initial state kinematics, are an ideal environment to study semileptonic and leptonic decays of the $B$ meson. Combined with theoretical inputs, measurements of both inclusive and exclusive decays yield information about the Cabibbo-Kobayashi-Maskawa matrix elements $V_{cb}$ and $V_{ub}$. We review our latest results, which include the first Belle$~$II results with fully leptonic and inclusive semileptonic decays.
