Abstract: The Belle experiment has given a substantial contribution in the field of heavy quarkonia. Several new states were announced by Belle for the first time, in both charmonium and bottomonium spectrum, or the confirmation from Belle corroborated former observations. Belle II is a next-generation experiment, which aims to continue and expand further the Belle physics program. We report in this document about the current status of the experiment and early physics results. Particular attention is devoted to the results of the analyses of the data sets collected during the energy scan (Nov 2021).
