Abstract
The Belle II experiment will operate with SuperKEKB $e^+ e^-$ energy-asymmetric collider on
or near the $\Upsilon (4S)$ resonance energy region, and aims at obtaining an integrated luminosity of
$50 ~\rm ab^{-1}$, which is approximately 50 times that of KEKB. The Belle II detector is fully upgraded
from the Belle detector for much higher luminosity and contains new trigger system for single
photon and low multiplicity events. The new trigger system allows to search for new physics related
with hidden portal or axion-like particles. We briefly review the existing dark sector studies
by BaBar and Belle, and report on the status of Belle II studies of dark sector, in particular for
vector and axion portals.
