  Quarkonium is the bound state of a heavy quark and its anti-quark
counterpart. The study of this system has experienced a renaissance thanks to
results from e+e- collider experiments, including discoveries of long-predicted
conventional quarkonia, and unusual states consisting of four quarks. The Belle
Experiment operated at KEK in Japan from 1999-2010. Analysis of the collected
data continues to produce new findings. The Belle II experiment is a
substantial upgrade of both the Belle detector and the KEKB accelerator, aiming
to collect 50 times more data beginning in 2018. This talk presented recent
Belle results related to hadronic and radiative decays in the bottomonium
system. It described the capabilities of Belle II to explore these topics, with
a particular focus on the physics reach of the first data, where unique
opportunities exist to make an immediate impact in this area.
