The famous exotic hadron $X(3872)$ (a.k.a. $\chi_{c1}(3872)$) is observed not only in $J/\psi \pi \pi$ but also in $D^0\bar{D}^{*0}$, and the observed mass and width are larger in the latter decay mode with sizable uncertainties. In this presentation, we report a new measurement on
$X(3872) \to D^0\bar{D}^{*0}$ decay using the full data of the Belle experiment and show the result of an analysis on the obtained spectrum shape with the Flatte-like model used in the $X(3872) \to J/\psi \pi^+ \pi^-$ by LHCb [PRD102(2020)092005].
