Description
The Belle and Belle II experiments have collected a unique sample of data at centre-of-mass energies above the $\Upsilon(\text{4S})$ resonance. We present several results related to hadronic transitions between bottomonium states such as $\Upsilon(\text{5S}) \to \Upsilon(\text{1S,2S})\eta$, $\Upsilon(\text{5S, 10753}) \to \Upsilon(\text{1S,2S})\pi^+\pi^-$, $\Upsilon(\text{5S}) \to h_b(\text{1P,2P})\pi^+\pi^-$, and $h_b(\text{1P,2P}) \to \Upsilon(1S)\eta$.
