In the "Shinsen Shojiroku" (Newly Compiled Register of Clan Names and Titles of Nobility), Nigihayahi was Tenjin (a deity from Takamagahara, who was not in the imperial line) while Amenohoakari was Tenson (the Imperial lineage, a descendant of Amaterasu).
『新撰姓氏録』ではニギハヤヒは、天神（高天原出身、皇統ではない）、天火明命（アメノホアカリ）は天孫（天照大神の系）とし両者を別とする。
