The Belle experiment is an experiment with focus on the physics of B-mesons (similar to the LHCb experiment, see also the BaBar experiment).
After the discovery of the Higgs field at the two major other detectors of LHC, these B-meson experiments currently stand out as seeing hints for physics beyond the standard model of particle physics with considerable statistical significance: the flavour anomalies (see Adamczyk 19)

Outlook for Belle II to confirm the flavour anomalies, if they are real:
With … Belle II, we are at the brink of a new era in quark flavour physics we present a phenomenological study of the potential for Belle II to reveal possible new physics in the inclusive decay channel.
(p. 15:) We see that anomalies in the exclusive sector can be confirmed at the 5σ level by inclusive measurements if the true values of are at the current best-fit point of the exclusive fits
(p. 16:) After including , the reach in the plane improves considerably. Exclusive anomalies could be confirmed at the 6σ level.
(p. 20:) Should the true value of and be at the current best-fit points of the global fits, an analysis of inclusive at Belle II with of data will exclude the SM point at the level of σ. This again underlines the necessity of a full angular analysis of at Belle II.
