Abstract	The Belle II experiment has accumulated data corresponding to 89.99 fb-1 integrated luminosity in the past 2 years, and is performing very well. We present here the analysis of B -> K J/psi pi pi and B -> K psi(2S): in the former for the first time the evidence for the X(3872) --->Jpsi pi pi has been found at Belle II, which is consistent with the observation at Belle of the same resonant state.
