Does the visible sign indicate that you are entering a one-way traffic?

The circular blue sign visible under the "give way" sign is C-12 "roundabout," which mandates movement around an island or square in the direction indicated by the arrows. Entry into a one-way street, however, is signaled by the rectangular sign D-3 "one-way street." Sign C-12 is a mandatory sign defining the traffic layout at the intersection, not an information sign about a one-way road.
