Although his graveyard is not known exactly, according to the section on the second year of the Tenan era (858) in "Nihon Sandai Jitsuroku", there is mention that 'Tonomine's grave shall be made the grave of FUJIWARA no Kamatari, as one of Four Graves of Ten Imperial Mausoleums,' and according to "Tonomine Ryakuki" (Brief Records of Tonomine), there is a theory that he was buried in Ai, Settsu Province (present-day Ibaraki City, Osaka Prefecture) at first, but reburied later in Tonomine, Yamato Province.
墓処は定かではないが、『日本三代実録』天安(日本)2年（858年）条には「多武峰墓を藤原鎌足の墓とし、十陵四墓の例に入れる」という記述があり、平安時代中ごろ成立と見られる『多武峯略記』などに「最初は摂津国安威（現在の大阪府茨木市）に葬られたが、後に大和国の多武峯に改葬された」との説が見える。
