His clan was also known as Omiwa, which could either be written as '大三輪' or '大神'in Chinese characters, and by the modern kana usage (as laid out by the Japanese government in 1946) it becomes 'Omiwa,' and with the old Japanese syllabary charaters, it is read 'Ohomiwa.'
氏は大三輪、大神ともいい、現代仮名遣いで「おおみわ」、旧仮名遣いで「おほみわ」となる。
