The name of the king of Wa (written as 俀 in Japanese, but it is generally said that the Chinese character of 俀 should actually be 倭), whose last name was Ame, was Tarashihiko (written as 多利思北孤 in Japanese, but it is generally thought that the character 北 had been originally 比 and his name should be written as 多利思比孤), and it is thought that his full name, Ametarashibiko, meant a noble man who was originally from heaven.
俀王（通説では俀は倭の誤りとする）姓の阿毎はアメ、多利思北孤（通説では北は比の誤り多利思比孤とする）はタラシヒコ、つまりアメタラシヒコで、天より垂下した彦（天に出自をもつ尊い男）の意とされる。
