Kokushi genzaisha
The Rikkokushi or the Six Official Histories, includes Nihon shoki, Shoku nihongi, Nihon kōki, Shoku Nihon Kōki, Montoku jitsuroku, and Sandai jitsuroku. Kokushi gensaisha are also called kokushi shozaisha or "shrines that appear in the Official Histories". These shrines are important because they have a historical significance and are regarded as ancient shrines. Some of the shrines listed in the Jinmyōchō (Register of Deities) in Engishiki, also known as Myojin Taisha also overlap with the kokushi genzaisha, but the term usually refers to shrines that are only mentioned in the Official Histories.
