Abstract: The Belle II experiment at the SuperKEKB $e^+e^-$ collider is one of the few facilities that can efficiently study the bottomonium spectroscopy and the only one where bottomonium is produced in formation. In 2021 Belle II has taken data around $\sqrt{s} = 10.75$ GeV to better study the Y(10753), a bottomonium-like state discovered by Belle and whose nature is still unclear. This talk will present all the most recent results obtained from this dataset on hidden- and open-beauty final states, and will briefly discuss the future opportunities offered by Belle II in the quarkonium sector.
