We report the result from the first search for D0 decays to invisible final states. The analysis is performed on a data sample of 924 fb-1 collected with the Belle detector at the KEKB collider. The absolute branching fraction is determined by using an inclusive D0 selected by the charm tagger method. The analysis procedure and measurement result will be reported.
