His name is written as "安萬侶" in "Kojiki" (The Records of Ancient Matters) and on his epitaph, but it is written as "太安麻呂" in other history books such as "Shoku Nihongi" (Chronicle of Japan Continued), "Koninshiki (one of Nihonshoki Shiki [The Private Record of Chronicles of Japan] written in the Konin Period)" and "Nihongi kyoen waka (The Poems at the Completion Banquet for the Lectures on Nihon Shoki)".
『古事記』や墓誌銘には「安萬侶」とあるが、『古事記』以外の史書（『続日本紀』、『弘仁私記』、『日本紀竟宴和歌』など）では「太安麻呂」となっている。
