SuperKEKB aims at obtaining the integrated luminosity of $50~{\rm ab}^{-1}$, which is approximately 50 times that of KEKB. The Belle II detector is fully upgraded from Belle detector for the high 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. In this talk, we 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.
