During the period of approx. 100 years from 592, when Emperor Suiko ascended the throne at Toyura no miya Imperial residence, to 694, when Empress Jito transferred the capital to Fujiwara-kyo (the ancient capital of Fujiwara), Imperial palaces were located in a concentrated manner in and around the Asuka region, which was in the south of Nara, so it is sometimes called Asuka-kyo (the ancient capital of Asuka).
592年に推古天皇が即位した豊浦宮から694年持統天皇が藤原京へ遷都するまでの約100年間は、奈良の南の地飛鳥周辺に宮殿が集中したので飛鳥京と呼ぶことがある。
