Abstract	We report recent results from Belle and Belle II related to exotic hadrons. We discuss the possibility that there are two states in the region near Upsilon(5S) [Energy dependence of the e+e- --> Bs()Bs()bar cross section at Belle]. We point out to some evidence that there exist a P-wave BBbar molecular state near the BBbar threshold [Energy dependence of the e+e- --> BBbar, BBbar and BB*bar cross sections at Belle II]. We also report new results on the properties of the recently observed vector state Upsilon(10753).
