In 1707 when a residence of a bugyo officer moved to an area within the gate of Sukiya-bashi Bridge on the southernmost side from an area within the gate of Tokiwa-bashi Bridge, the new residence became to be called the minami-bugyo-sho office due to its location.
宝永4年（1707年）に本来北町奉行所であった常盤橋門内の役宅が一番南側の数寄屋橋門内に移転した際には、その場所ゆえに南町奉行所と呼ばれるようになった。
