For the Karasuma Line, placed at the level immediately under the gate-installed level, two separate platforms with two tracks served between them, the structure of this type being used only here on the Karasuma Line, are provided (having been designed to allow passengers to change trains with Tozai Line here), while an island platform serving two tracks is provided for the Tozai Line placed at the level immediately under the Karasuma Line level.
プラットホームは、改札階の下にある烏丸線ホームが同線で唯一の相対式2面2線（開業時から東西線との乗り換え駅となる事を見越しての設計であった）、そのさらに下層にある東西線ホームが島式1面2線となっている。
