Emperor Kōbun
Kōbun's reign lasted only a few months in 671–672. Traditional narrative. Emperor Kōbun was named the 39th emperor by the Meiji government in 1870; and since the late 19th century, he is known by the posthumous name accorded to him by Meiji scholars. In his lifetime, he was known as Prince Ōtomo (大友皇子, "Ōtomo no ōji"). He was the favorite son of Emperor Tenji; and he was also the first to have been accorded the title of "Daijō-daijin." Contemporary historians now place the reign of Emperor Kōbun between the reigns of Emperor Tenji and Emperor Tenmu ; but the "Nihongi", the "Gukanshō", and the "Jinnō Shōtōki" do not recognize this reign. Prince Ōtomo was only given his posthumous title and name in 1870. The actual site of Kōbun's grave is known. This emperor is traditionally venerated at a memorial Shinto shrine ("misasagi") at Shiga. The Imperial Household Agency designates this location as Kōbun's mausoleum. It is formally named "Nagara no Yamasaki no misasagi". Non"-nengō" period. The years of Kōbun's reign are not linked by scholars to any era or "nengō". The Taika era innovation of naming time periods – "nengō" – languished until Mommu reasserted an  imperial right by proclaiming the commencement of Taihō in 701. In this context, Brown and Ishida's translation of "Gukanshō" offers an explanation about the years of Empress Jitō's reign which muddies a sense of easy clarity in the pre-Taiho time-frame: Section::::"Kugyo". The top during Emperor Kōbun's reign included: Consorts and children. Empress Consort: Princess Tōchi (十市皇女), Emperor Tenmu’s daughter Empress: Fujiwara no Mimimotoji (藤原耳面刀自), Fujiwara no Kamatari’s daughter Emperor Kōbun had another son named Prince Yota (興多王), whose mother is unknown.
