| 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. |
