Study of Transitions and Decays of Bottomonia at Belle
  We review the studies of transitions and decays of bottomonium states from the e+ e- data recorded by the Belle detector at various Upsilon-resonances. We also report a recent study of the branching fractions of \chi_{bJ}(1P) to 41 hadronic final states in the Y(2S) data sample. In the same study, a 90% confidence-level upper limit is set for the first time on the width of \chi_{b0}(1P) at \Gamma_{total} < 2.4 MeV.
