The present invention is to provide a highly safe method for producing hydrogen peroxide by the anthraquinone method and a production system. The present invention provides a method for producing hydrogen peroxide comprising: (A) a hydrogenation step of supplying a working solution comprising a solvent and anthraquinone, a hydrogenation catalyst, and a hydrogen-containing gas into a hydrogenation reaction vessel, reducing the anthraquinone, and producing anthrahydroquinone (B) an oxidation step of producing hydrogen peroxide by converting the anthrahydroquinone contained in the working solution from step (A) into anthraquinone in an oxidation tower (C) an extraction step of separating the hydrogen peroxide, which is contained in the working solution from step (B), from the working solution (D) a finishing step of purifying and concentrating the hydrogen peroxide from step (C) and (E) a circulating step of returning at least a part of the working solution from step (C) to step (A) the method further comprising: (F) a step of withdrawing an oxidation drain and a part of the working solution generated in step (B) from a bottom part of an oxidation tower as a withdrawn liquid, separating the withdrawn liquid into a working solution and hydrogen peroxide, and sending the separated working solution into step
