Abstract: The Belle and Belle II experiments have collected a 1.1 ab$^{-1}$ sample of collisions at the resonance. We present results on the radiative decays $B^0 \rightarrow \gamma \gamma$, $B \rightarrow \rho \gamma$ and $B \rightarrow K^* \gamma$. CP and isospin asymmetries are presented for the latter two decays We also present results from decays involving $b \rightarrow s \ell^+ \ell^-$ and $b \rightarrow d \ell^+ \ell^-$ transitions, where $\ell$ is an electron or muon.
