Abstract : Many astronomical and astrophysical observations strongly suggest the existence of dark matter, but the Standard Model of elementary particle physics does not accommodate it. The dark sector is a hypothetical sector of dark matter particles along with the interactions amongst them. Therefore, it is of utmost importance to experimentally confirm and understand the dark sector. In this lecture, we present the studies of the dark sector from the Belle and the Belle II experiments. The Belle II is a high-luminosity e+ e- collision experiment using the energy-asymmetric collider SuperKEKB, while Belle is the predecessor experiment of Belle II. Currently, the SuperKEKB holds the world record of collider luminosity at 4.7x10^34 / (cm s). The lecture will start with a brief introduction of the two experiments along with a few key physics achievements, then conclude with the recent studies of the dark sector.
