The first measurements of differential branching fractions of inclusivesemileptonic ${B \to X_u \, \ell^+\, \nu_{\ell}}$ decays are performed usingthe full Belle data set of 711 fb$^{-1}$ of integrated luminosity at the$\Upsilon(4S)$ resonance and for $\ell = e, \mu$. Differential branchingfractions are reported as a function of the lepton momentum, thefour-momentum-transfer squared, light-cone momenta, the hadronic mass, and thehadronic mass squared. They are obtained by subtracting the backgrounds fromsemileptonic ${B \to X_c \, \ell^+\, \nu_{\ell}}$ decays and other processes,and corrected for resolution and acceptance effects. The measured distributionsare compared to predictions from inclusive and hybrid ${B \to X_u \, \ell^+\,\nu_{\ell}}$ calculations.
