Description
The Belle and Belle$~$II experiments have collected a $1.4~\mathrm{ab}^{-1}$ sample of $e^+e^-$ collision data at centre-of-mass energies near the $\Upsilon(nS)$ resonances. This sample contains approximately 1.3 billion $e^+e^-\to \tau^+\tau^{-}$ events, which we use to search for lepton-flavour violating decays. We present searches for tau decay to three charged leptons, $\tau^-\to K_{\rm S}^0\ell^{-}$, $\tau^-\to\Lambda\pi^-$, $\tau^-\to \bar{\Lambda}\pi^-$ and $\tau^-\to \ell^-\alpha$, where $\alpha$ is an invisible scalar particle.
