The Asuka-Fujiwara cluster consists of 19 archaeological sites dating from the late sixth to the early eighth century. Major sites include the ruins of the Asuka Palace (飛鳥宮跡 Asuka-kyū Ato) and Fujiwara Palace (藤原宮跡 Fujiwara-kyū Ato), both linked to the formation of Japan's early centralised state, as well as the remains of Fujiwara-kyō (藤原京), considered Japan's first full-scale planned capital. The nomination also includes Buddhist temple ruins and ancient burial mounds (kofun 古墳). Among the best-known tombs are the Takamatsuzuka Mounded Tomb (高松塚古墳 Takamatsuzuka Kofun), famous for its vividly coloured wall paintings, and the Kitora Mounded Tomb (キトラ古墳 Kitora Kofun), which contains what is regarded as the oldest astronomical chart discovered in East Asia. According to UNESCO's World Heritage Centre, the ruins demonstrate strong cultural and technological influences from mainland China and the Korean Peninsula, reflecting the close contacts that existed between Japan and other parts of East Asia during the formation of the early Japanese state.
