South of the platforms there is another station building beneath the platforms of the Kintetsu Line and the Shinkansen, which was constructed when the Shinkansen went into operation; however, it underwent a slight change during the renovation due to its small size except for the construction of the Nanboku-Jiyu-Tsuro and the complete separation of the ticket wicket of the JR Line from that of the Kintetsu Line.
なお、ホーム南側にも駅舎があるが、これは新幹線開通時に建設されたもので近鉄・新幹線のホーム下にあり、規模は小さく、新駅ビル建設の際も南北自由通路の設置やJR線と近鉄線の改札を完全分離化した事以外は大きな変更はなかった。
