Tau physics at Belle and Belle II

Abstract

We present here the major results obtained in $\tau$ physics by the Belle and Belle II experiments. For the Belle II experiment, we also discuss prospects for improved measurements of the $\tau$ lepton properties, new results in Michel parameters determination, and searches for $CP$ and lepton flavor violation in $\tau$ decays.
