Understanding early thermalization is a theoretical challenge in relativistic heavy-ion collisions. In this talk, we investigate the thermalization problem by using the Husimi-Wehrl (HW) entropy defined by the Husimi function which is a coarse-grained quantum-distribution function. We propose numerical methods to calculate the HW entropy from the semi-classical time evolution of the Yang-Mills field. We show the HW-entropy production from the phenomenological initial configuration motivated by the McLerran-Venugopalan model in a static box and discuss the relation to the isotropization of the pressure and the relaxation of the local energy distributions.
