000004589 520__ $$aBelle and Belle II experiments gathered around 1.5 ab$^{-1}$ of dataset near $\Upsilon(nS)$ resonances, which have constrained kinematics and low multiplicity suitable for dark sector searches. Both experiments have excellent sensitivity for dark sector searches in the few MeV - 10 GeV range. The latest dark sector searches performed by both collaborations, which constrain a variety of dark mediators, are discussed.
