Belle II is a next generation B-factory experiment at the SuperKEKB collider. In early 2019 the fully operational detector will start taking data. The goal is to collect a statistics 50 times larger than the one collected by its predecessor Belle, namely an integrated luminosity of $50~\mathrm{ab^{-1}}$.
The Belle II tracking detectors are designed to reconstruct charged particles trajectories whose momentum can be as small as $50~\mathrm{MeV/c}$ with excellent resolution on both impact parameters and momentum. In this contribution, the tracking and vertexing algorithms implemented in the Belle II software framework are presented, together with the performances on simulated $\Upsilon (4S) \rightarrow B\bar{B}$ events and on data collected during the detector commissioning phase.
