Abstract	We report a study of the rare decay B0 → γγ, using data accumulated by the Belle and Belle II experiments and corresponding to integrated luminosities of 694 fb−1 and 362 fb−1, respectively. The datasets were collected through electron-positron collisions at center-of-mass energy corresponding to the Υ(4S) resonance. The combined measurement of the branching fraction will be presented in this talk.
