In this situation, can you turn right without stopping before the signalling device?

No. The S-2 traffic light with a green arrow, the so-called 'conditional arrow', permits a right turn, but only on the condition that you stop before the traffic light. Stopping is mandatory in order to give way to other road users (e.g., vehicles on the intersecting road and pedestrians) who have a green light. Proceeding without stopping is an offence.
