Aya clan
Aya clans (漢氏, Aya-shi) were collectively known immigrant clans from Korea that were active in Japan since the Kofun period according to the Kojiki (712), Nihon Shoki (720), and Shoku Nihongi (797). The three main branches of the Aya clan included the Yamato no Aya clan, Kawachi no Aya clan, and the Ayahito clan; though claiming different founders, they all shared the same character of "Aya" in their names and are considered ethnically related.
