Although the year of her death was unknown, according to Nagaya-o gankyo (the transliterated text of handwritten sutra of Nagaya-o [also known as the Jinki sutra]) that was believed her son, Nagaya-o dedicated in 728 (to hold a memorial service of his parents), it is considered that she died before 728.
没年は未詳であるが、息子・長屋王が神亀5年（728年）に奉納したと言われる長屋王願経（神亀経）の釈文（写経の目的は父母の菩提を弔う、とする）から、神亀5年以前には亡くなっていたものと考えられる。
