The Suzakumon (朱雀門, Suzakumon or Shujakumon?) was the main gate built in the center of the south end of the imperial palaces in the Japanese ancient capitals of Fujiwara-kyō (Kashihara), Heijō-kyō (Nara), and later Heian-kyō (Kyoto). The placement followed the ancient Chinese palace model requirements at the time, where Suzaku (朱雀, Suzaku?), the Vermilion Bird was the Guardian of the South. (See Four Symbols for more.)
